m If you have additional equipment for your computer, see Chapter 2, “Using

Expansion Bay Modules and PC Cards,” and Chapter 3, “Connecting Additional Equipment,” for instructions. (If you are a new Macintosh user, you should complete “Learning the Basics” in Mac OS Help before connecting additional equipment.)

Chapter 1

Read this chapter for

information on using expansion

bay modules and PC Cards.

Using expansion bay modules

The floppy disk drive and the CD-ROM drive for your Macintosh PowerBook are removable modules, which you can easily switch or replace with another module. The place in your computer where modules go is called the

expansion

bay. (The floppy disk drive is installed in the expansion bay at the factory.)

You can switch the modules, such as the floppy disk drive, CD-ROM drive or PC Card storage case, or remove a module while the PowerBook is turned on, in sleep, or shut down. All expansion bay modules are inserted and removed in the same way.

To protect your work and to be sure that the computer recognizes which module is in use, first quit any programs that may be using files on the disk i n that module. T hen select the disk’s icon and choose Put Away from the File menu or drag the icon to the Trash.

IMPORTANT

Don’t switch modules while the computer is starting up. Also take care not to remove a module if a floppy disk or CD-ROM disc is inserted and in use.

If you purchase an expansion bay module from an independent supplier, b e sure to follow the instructions that came with the device. Some modules may have special requirements, such as shutting down the computer before inserting or removing the module. At least one manufacturer makes an internal power adapter for use in the expansion bay.

Using Expansion Bay Modules and PC Cards

Removing an expansion bay module

To remove a n expansion bay module from your Macintosh PowerBook, follow these steps:

1 Quit any application programs or files that are using the floppy disk or compact disc

(CD) or other medium inserted in the expansion bay module.

Remember to save your work.

2 If a floppy disk or CD is inserted in the module, click its icon to select it and drag its icon

to the Trash (or choose Put Away from the File menu).

You should not remove the module if a disk is in use. If you have any other kind of optional expansion bay module, make sure you drag the icon for its media to the Trash or select the icon and choose Put Away from the File menu.

3 Unlock the expansion bay module by sliding the module release latch on the bottom of

your Macintosh PowerBook in the direction of the arrow.

To unlock the module, slide the latch on the underside of the computer.

Chapter 2

4 Hold the module by the gripping surface and pull it out of the computer.

IMPORTANT

You should not remove an expansion bay module if it is in use or you may lose data. If you try to remove the module when it is in use, you’ll see a message telling you to reinsert it. Reinser t the module, quit any files or programs that may be using the floppy disk (or other medium inserted i n the module), then select the disk’s icon and choose Put Away from the File menu or drag the disk’s icon to the Trash. (If the module contains the startup disk, you can’t remove the module or drag the disk to the Trash.)

To be sure that you don’t get another in-use message, wait 5 seconds after quitting programs and ejecting a disk before you remove the module.

If you put your computer to sleep while a floppy disk or other medium is inserted, the green i n-use light to the left of the module will flash (similar to the sleep indicator light on your computer’s display). You should not remove the module while the in-use light is on or flashing.

Hold the module by the gripping surface and pull it completely out of the computer.

The module release latch automatically slides back into its proper position as you remove the module.

Gripping surface

Using Expansion Bay Modules and PC Cards

Inserting an expansion bay module

To reinsert the expansion bay module, slide the module in. Make sure the gripping surface is facing down. The release button automatically returns to the locked position.

Be sure the module is completely inserted. If it does not insert properly, reset the module release latch to the unlocked position (as in step 3 earlier) before reinserting the module.

The expansion bay can use a wide component, such as the 5.25-inch CD-ROM drive, or a narrower component, such as the 3.5-inch floppy disk drive. When a narrower device is in the expansion bay, a small flap covers the empty part of the bay. When a wider drive is inserted, the flap folds into the bay.

Note: A plastic storage case for PC Cards is provided with your PowerBook. This case fits into the expansion bay. If you want to make the computer as light as possible, you can remove the module in the expansion bay and insert the PC Card storage case. Always keep a module or the PC Card storage case in the expansion bay to protect the connectors inside the bay.

Flap for narrow module

Chapter 2

Using a CD in the CD-ROM drive

You i nsert or remove the CD-ROM drive in the same way as any other module.

Inserting a disc

To load a compact disc in the drive, follow these steps:

1 Start up the PowerBook, if it’s not already on. 2 Press the Open button on the outside of the CD-ROM module to open its tray.

The tray opens part way. (If the tray doesn’t open, a disc may already be in the drive. Drag its icon to the

Trash to open the tray. You’ll see a message if the disc is in use; in that case, quit the program in use or close the disc’s window if no program is in use.)

3 Pull the tray all the way open and place a CD-ROM disc in the tray, with the label facing up.

Make sure the disc is lying flat in the tray and is seated firmly on the spindle. Avoid touching the drive’s lens.

Insert the disc, label side up.

Using Expansion Bay Modules and PC Cards

4 Push the tray in to close it.

When the CD-ROM drive is in use, you may notice some vibration and noise as the compact disc spins rapidly. Certain discs can cause the drive to vibrate because they have heavily inked artwork or a label that creates an imbalance.

Variations in speed of CDs is normal. Different types of disks run at different speeds; for example, audio CDs all r un at a low speed.

The high-speed CD-ROM drive for your PowerBook contains an intelligent sensor that detects an unbalanced disc and adjusts the disc speed to minimize vibration. Even when the speed changes, the CD still functions normally, but it may transfer information at a somewhat slower rate.

Some vibration is not unusual for a high-speed CD-ROM drive, in part because there is no specification for balance of compact discs. To mi nimize vibration from unbalanced compact discs, do not put labels on your CDs. Place the computer on a flat, solid surface when using the CD-ROM drive.

Keep the CD-ROM drive’s tray closed except when loading discs. This prevents dust from getting inside the mechanism. Also be sure to keep the CD’s recorded surface (the side opposite the label) free of contamination such as fingerpri nts, dust, and grease. T he performance of the drive depends on the optical quality of the CD media.

Chapter 2

Ejecting a disc

Follow these instructions to open the tray and eject a CD-ROM disc from the drive:

1 Open the tray.

There are several ways to open the tray of your CD-ROM drive.

If a CD-ROM disc icon appears on your screen, do one of the following:

m Select the disc icon on your screen and drag the icon to the Trash. m Click the disc icon and choose the Put Away command i n the File menu. m While the CD player’s window is active, choose Eject CD from the File

menu, or simultaneously press the x and E keys. (Do not remove the module if you use this method of ejecting the disc.)

m Use the pop-up menu in the CD section of the Control Strip to eject a CD.

If no CD-ROM disc icon appears on your screen, do this:

m Press the Open button on your CD-ROM drive.

2 Take the disc out of the tray.

Store your disc in a safe place, away from heat, dust, and moisture.

3 Push the tray in to close it.

To avoid possible damage to the tray or the drive, keep the tray closed when you are not using it.

Using Expansion Bay Modules and PC Cards

If you still can’t eject a disc, try this method:

If the standard methods of ejecting a CD do not work (or the computer is shut down), you can eject the disc manually. Carefully insert the end of a straightened paper clip into the small hole near the CD-ROM drive’s opening, and push firmly until the tray disengages. Pull the tray open, remove the disc, and close the tray.

Insert the end of a large, straightened paper clip into this hole.

Chapter 2

Locking an expansion bay module

You can purchase a security cable and lock to protect your Macintosh PowerBook. With a lock, you can do the following:

m secure your computer to a desk or table m lock the expansion bay module and battery in your computer

See your Apple-authorized dealer or computer retailer for details on what security devices are available.

Using Expansion Bay Modules and PC Cards

Using PC Cards (PCMCIA cards)

PC Cards (also known as PCMCIA cards) are about the size of a thick credit card and have a 68-pin connector at one end. They come in many varieties, such as fax/modem cards, mass-storage cards, Ethernet connection cards, and wireless communication cards. You can use PC Cards to expand your Macintosh PowerBook’s capabilities.

This section describes how to insert and eject PC Cards and how to set up your communications software to use PC Card modems. For information on using PC Cards, see the “Using PC Cards” topic area of Mac OS Help, available in the Help menu.

Your Macintosh PowerBook has two PC Card slots: an upper slot and a lower slot. You can insert a card into either slot, or you can use both slots simultaneously.

There are three types of PC Cards. T h e different types refer to the thickness of the card. A Type I card is 3.3 millimeters (mm) thick, a Type II card is 5 mm thick, and a Type III card is 10.5 mm thick. Make sure you check the documentation that came with your PC Card to verify that it is compatible with your Macintosh PowerBook.

You can place a Type I or Type II card in either the upper or lower slot. You can place a Type III card only in the lower slot. When a Typ e III card is in the lower slot, you cannot use the upper slot. You may find it useful to get in the habit of always using the lower slot to make sure the card you are using is properly inserted.

A special type of PC Card supports “Zoomed Video,” a method of showing full-motion video images in a window on the computer’s screen. Your PowerBook is designed to use a Zoomed Video card, but this type of card must be placed in the lower PC Card slot.

WARNING

Make sure you only use cards that are designated by the PC Card manufacturer as compatible with your Macintosh PowerBook. If you use an incompatible card, you may damage the card or your PowerBook. If you are not sure whether a PC Card is compatible with your PowerBook, contact the PC Card manufacturer.

Chapter 2

Inserting a PC Card

To insert a card, do this:

Insert the card, connector first and label up, into the slot. Make sure the card is level.

A Type III PC Card or a Zoomed Video card must be inserted in the lower slot.

A Type I or Type II PC Card can be inserted in either the upper or lower slot.

Using Expansion Bay Modules and PC Cards

You’ll feel some resistance as you slide the card in. When the card is firmly seated, you will feel it click into place. Consult the card’s documentation for details of its use.

An icon for the PC Card appears on the desktop. You are now ready to use the card.

Ejecting a PC Card

Your computer must be on or off to eject a PC Card. You cannot eject a PC Card when the computer is in sleep.

IMPORTANT

Before you eject a card, make sure that nothing is blocking the card’s slot. If you want to use the card again immediately, pull it out about an inch more and then push it back in. (If you don’t follow this procedure and you try to push the card back in to use it again, the card will not engage properly.)

To eject a PC Card when the computer is on, follow these steps:

1 If the computer is in sleep, press the Power key (or any key on the keyboard except Caps

Lock) to wake it.

2 Click the PC Card’s icon to select it. 3 Choose Put Away from the File menu. 4 Pull the card out of the slot.

IMPORTANT

Do not pull or force a PC Card out of the slot. Doing so may damage your computer or PC Card.

Other ways to eject a PC Card when the computer is on include the following: m Click the card’s icon to select it. Drag the card’s icon to the Trash. After the

card is ejected, pull it out of the slot.

m Click the card’s icon to select it. Open the Special menu and choose Eject

PC Card. After the card is ejected, pull it out of the slot. (If a dimmed icon of the card remains on the desktop, you can drag it to the Trash.)

Chapter 2

To eject a PC Card when the computer is on or off, do this: m Press the eject button next to the slot containing the PC Card you want to

eject. (The eject buttons do not work if your computer is in sleep.) If the card is not in use, it will usually be ejected. If the card won’t eject, you’ll see an alert message.

Try to use the eject buttons only when the computer is turned off. Many PC Cards won’t eject when the button is pressed if the computer is on.

If you can’t eject a card

If you are unable to eject a card, follow these steps:

1 Straighten one end of a paper clip.

Press the eject button next to the slot with the PC Card in it.

Using Expansion Bay Modules and PC Cards

2 Insert the end of the straightened paper clip into the hole next to the slot that contains

the card, and press gently but firmly until the card is ejected.

3 Pull the card out of the slot.

Setting the computer not to eject storage PC Cards at startup

If a you have a storage PC Card, such as an SRAM card or an ATA hard disk, in either slot, the card will be ejected when the computer starts up. To prevent excessive wear on PC Card connectors and slots, you can use the Startup Disk control panel to keep storage PC Cards from ejecting when you turn on the computer. (Other typ es of PC Cards, such as a modem or Ethernet card, are not ejected at startup.)

Follow these steps to avoid having a storage PC Card eject at startup:

1 Open the Startup Disk control panel.

If you need instructions for opening the control panel, see “How do I make a disk the startup disk?” in the Disks topic area of Mac OS Help, available in the Help menu.

2 Click the icon for the computer’s hard disk to select it.

If you can’t eject a card, insert the end of a straightened paper clip into the hole next to the slot. This hole is for the upper slot.

3 Close the control panel.

The PC Card storage device will no longer eject at startup.

Using a Zoomed Video PC Card

The lower PC Card s lot in your Mac int osh PowerBook has circuitry for handling vi deo signals, called “Zoomed Video. ” Some independent manufacturers off er PC Cards to which you can provide a video signal or connect a video camera. The Zoomed Video PC Card is a Type II card; it can only be used in the lower slot (because the special circuitry needed for video signals is located in that slot).

With a Zoomed Video card in the lower PC Card slot, the PowerBook ca n display video on the computer’s screen or on an external monitor. Video signals are sent directly to the video controller, so that the computer can display full-motion video while performing other tasks at the same time.

If you purchase a Zoomed Video PC Card, be sure that it has software that works with your PowerBook.

Using a PC Card modem

When you are using a PC Card modem, make sure you do the following:

1 Install the communications software you want to use, as well as any software that came

with your modem.

See the documentation that came with your modem and your communications software for instructions on setting up a PC Card modem for each application. Check to see if PC Card modem files for your software were included. You can get other modem files from the manufacturer of your modem or your communications software.

2 Insert the PC Card modem.

When a PC Card modem is inserted, an icon like the one pictured below appears on the desktop:

Some card manufacturers may use a custom icon.

For information on connecting and using a PC Card modem, see the documentation that came with your modem, as well as “Using a PC Card Modem” in the section “Using PC Cards (PCMCIA Cards)” in Chapter 2 of this manual, and the “Using PC Cards” topic area of Mac OS Help, available in the Help menu.

You can also connect an external modem to the modem/printer port on the back panel of the computer. The modem/printer port is GeoPort-compatible.

To connect an external modem, follow these steps:

1 Make sure the computer is in sleep or shut down. 2 Connect the modem to a power source and to the phone line. 3 Make sure the modem is turned off. 4 Connect the modem cable to the port marked with this icon:

5 Turn on the modem. 6 Wake or restart the computer. 7 Open the Chooser and select the icon for a network printer (such as LaserWriter).

You must select a printer to be sure that the modem/printer port is available for the modem.

8 Turn off AppleTalk in the Chooser.

If you see a message, click OK.

Note: If you are using an Ethernet or infrared connection, you don’t need to turn AppleTalk off.

The external modem is ready to use.

Connecting SCSI devices

A SCSI device is any product—including hard disk drives, CD-ROM drives, and scanners—that communicates with your computer by means of a standard electronic interface. (SCSI stands for Small Computer System Interface.) You can attach up to seven SCSI devices to your computer by linki ng them together in a chain that starts at your computer’s SCSI port.

To connect a SCSI device to your Macintosh PowerBook, you need an Apple HDI-30 SCSI System Cable or equivalent. T his cable is light gray, is about 19 inches long, and has 29 pins (one “missing” pin).

Refer to the manuals that came with your SCSI devices for instructions on installing any necessary software, setting SCSI ID numbers, and connecting SCSI cables and SCSI terminators. Refer to the illustrations on the next page for the proper positioning of SCSI terminators. A SCSI chain of devices must include a terminator attached to the first and last devices in the chain (but nowhere else in the chain). Some devices include internal terminators. Your Macintosh PowerBook is internally terminated.

The names and the part numb ers of the cables mentioned in this chapter are the following:

Type of connection Name of part Part number

From your computer to Apple HDI-30 SCSI System Cable M2538**/A a SCSI device

From a SCSI device to Apple SCSI Peripheral Interface Cable M0207 a SCSI device

For SCSI disk mode Apple HDI-30 SCSI Disk Adapter Cable M2539**/A

WARNING

When connecting SCSI equipment, always turn off power to all devices in the chain, including your computer. If you don’t, you could lose information and damage your equipment.

Using your Macintosh PowerBook as a hard disk

You can purchase a cable called the Apple HDI-30 SCSI Disk Adapter that lets you connect your Macintosh PowerBook to another computer as a hard disk. The PowerBook’s internal hard disk drive appears on the desktop of the other computer as a hard disk icon, and you can transfer information between the computers by dragging files. T his feature is called SCSI disk mode.

The Apple HDI-30 SCSI Disk Adapter cable is dark gray, is about 10 inches long, and has 30 pins.

IMPORTANT

Whenever you use your PowerBook in SCSI disk mode, be sure that the power adapter is plugged in. If you connect the PowerBook as a SCSI disk under battery power, the battery’s low-power warni ng will not be displayed and the computer may shut down because the battery is drained.

Connecting Additional Equipment

Connecting your computer as a hard disk

Before making any connections, you need to assign a unique SCSI ID number to the PowerBook. (The unique ID number allows the computer to communicate with several connected devices.)

1 Choose Control Panels from the Apple (

) menu of your PowerBook.

2 Open the PowerBook Setup control panel.

3 In the SCSI disk mode section of the control panel, click the ID number you want

to assign.

If you are connecting the Macintosh PowerBook to an existing SCSI chain, make sure to give it an ID number different from those of the other devices. (Many devices include an ID number indicator on the back panel.)

4 Close the PowerBook Setup control panel. 5 Press the Power (π) key on the PowerBook once to get the Shut Down dialog box and

click Shut Down to turn the PowerBook off.

6 Shut down the computer you are connecting to and turn off any other devices in the

SCSI chain.

7 Connect the small connector on the Apple HDI-30 SCSI Disk Adapter to the SCSI port on

your PowerBook.

WARNING

Always shut down the PowerBook before connecting or disconnecting the SCSI disk adapter cable. Connecting the adapter cable while the computer is turned on can damage the computer.

Chapter 3

8 If you are connecting the Macintosh PowerBook directly to the other computer

(rather than to an external device in the SCSI chain), attach a SCSI system cable to the other computer.

9 Connect the large connector on the Apple HDI-30 SCSI Disk Adapter cable to a SCSI

cable attached to the SCSI port on the last device in the SCSI chain, or to the SCSI system cable on the other computer.

10 Turn on the PowerBook by pressing the Power key.

After a few seconds a SCSI icon appears on the screen, showing the ID number you assigned in step 3.

11 Turn on the other SCSI devices in the chain, if any. 12 Turn on the other computer.

The PowerBook’s internal drive appears as a hard disk icon on the screen of the computer you connected it to. You can now transfer and use files as if the Macintosh PowerBook were an external disk drive.

WARNING

If you do not see the SCSI icon, and the computer starts up normally or displays an error message, press the Power key to shut down (if you can) and then immediately disconnect your computer from the SCSI chain. (If you can’t choose Shut Down, try pressing the reset button. If you cannot shut down your Macintosh PowerBook, you should disconnect the cable anyway, or you may lose information.) Then go bac k and repeat steps 5 through 10, making sure to use t he proper cables.

You may not be able to have password protection turned on in the Password Security control panel while using your PowerBook in SCSI disk mode. Turn password protection off if you experience problems. See “How do I turn password security on and off” in the “Setting Options” topic area of Mac OS Help, available in the Help menu.

Connecting Additional Equipment

Drawing battery power in SCSI disk mode

Your Macintosh PowerBook continues to draw battery power when you use it as a hard disk. Therefore, it is preferable to connect the power adapter whenever you use the computer in SCSI disk mode.

In some instances a low power indicator may be displayed. This symbol is a blinking low-power warning on the PowerBook’s screen, like the icon below.

If you see this warni ng while using your computer as a hard disk, either plug in the power adapter or quit SCSI disk mode, as described in the next section, so you can recharge the battery.

Quitting SCSI disk mode

1 Shut down the computer your PowerBook is connected to. 2 Press the Power (π) key once on the PowerBook to get the Shut Down dialog box. 3 Turn off any other SCSI devices in the chain. 4 Disconnect the PowerBook from the adapter cable.

IMPORTANT

Do not leave the adapter cable attached to the PowerBook. If you do, the computer will behave as though it is still in SCSI disk mode when you try to restart.

5 If necessary, disconnect the adapter cable from the other computer or its SCSI chain.

Your equipment is now ready for normal use. If you disconnected the adapter cable from the other computer or SCSI chain, make sure that the SCSI chain is properly terminated.

Chapter 3

Using an external monitor

You can connect an external monitor to your Macintosh PowerBook. If you are familiar with other PowerBook models, you will note that the types of monitors you can use with this model and the way images are displayed on an external monitor differ somewhat from other PowerBook computers.

To make the best choice of an external monitor, keep in mind the following characteristics of your PowerBook’s hardware.

m Your PowerBook can support a variety of external monitors, including

17-i nch and 20-i nch multiple-scan displays. Resolutions supported range from 512 x 384 pixels to 10 24 x 768 pixels.

m The monitor port’s connector on the computer’s back panel is a VGA-style

connector. You can connect the cable for a VGA- or SVGA-style monitor directly to your PowerBook.

m To connect an Apple (or Apple-compatible) monitor to your PowerBook,

you must use the adapter that came with the computer (it has the number 590-0289 molded into it).

m Images can appear on the internal display, the external monitor, or both

screens, depending on your choice of resolution on the external monitor.

m When an image appears on both screens, it is exactly the same (known as

“simulscan” or mirroring). You cannot move the pointer or menu bar from one screen to the other (as you can when an external monitor is connected to other PowerBook models or to most Macintosh desktop models).

m When an external monitor offers the same resolution as the PowerBook’s

internal display (800 x 60 0 pixels at 60 hertz [Hz] refresh rate), the image appears on both screens the first time you turn on the computer (unless the PowerBook’s display is closed).

m The PowerBook is designed to be “plug-and-play” when an external

monitor is attached. If the monitor is Apple-compatible, the PowerBook tries to use the highest resolution possible. If the external monitor is not Apple-compatible but provides a list of its capabilities, the system uses that list of resolutions. If no list of resolutions is provided by the monitor, the system uses a resolution of either 800 x 600 pixels or 640 x 480 pixels as the default for that monitor.

Connecting Additional Equipment

m If the PowerBook starts up with the display closed (called “do cking mode”)

and an external monitor is attached, the PowerBook’s display do es not turn on and the display’s resolution (800 x 60 0) is not listed in the resolution section of the Control Strip.

For complete instructions on adjusting the resolution for an external monitor, see the “Monitors” topic area of Mac OS Help, available in the Help menu.

The list below shows the external monitors and the resolutions, refresh rates, and number of colors supported by your PowerBook.

Note:

Your PowerBook supports the Video Electronics Standards Association (VESA) Display Data Channel (DDC) Standard. Specifically, it supports the DDC2B transfer protocol. When a monitor supporting this standard is connected, the PowerBook automatically recognizes the resolutions the monitor can display. You use the monitor resolution section of the Control Strip or the Monitors & Sound control panel to change resolution.

Connecting Additional Equipment

Connecting an external monitor

To connect an external monitor to your PowerBook, follow these steps. Also consult the documentation that came with the monitor.

1 Press the Power (π) key once to get the Shut Down dialog box. 2 Click Shut Down or Sleep.

If you connect a monitor with your computer turned on, the computer will not recognize the monitor.

3 Place the monitor near the PowerBook.

Keep the computer and the monitor at least 8 inches apart. Interference between the monitor and your computer’s floppy disk drive can cause errors on your floppy disks.

Arrange the monitor so the top of the screen is slightly below eye level while you work. Position the monitor to minimize glare and reflections on the screen from lights and windows.

4 Make sure the monitor’s power cord is attached to the monitor. Plug the other end into a

grounded outlet or power strip.

If your monitor’s power cord is design ed to plug into the power receptacle on the back of a computer, rather than into an electrical outlet, you can obtain a cord with the correct plug from your Apple-authorized dealer.

If you are using a power strip, make sure it is turned on.

5 If you are connecting an Apple or Apple-compatible monitor, locate the adapter that

came with your computer and attach it to one end of the external monitor’s cable.

The monitor adapter is a small plastic and metal device that is the same color as the computer. Th e number 590-0289 is on the adapter.

If you are connecting a VGA or SVGA monitor, skip this step.

Chapter 3

6 Make sure the other end of the monitor’s cable is attached to the monitor. Then attach

the end of the cable (with the monitor adapter, if it’s an Apple-compatible monitor) to the external monitor port on the back of the PowerBook.

If you are c onnecting a VGA or SVGA monitor, do not use the adapter. Connect the monitor cable directly to the external monitor port on the PowerBook.

7 Turn on the external monitor. 8 Press the Power (π) key to turn on your computer. (You can press any key if your

PowerBook is in sleep.)

The external monitor is automatically activated. You can use the Control Strip to change the resolution on the monitor. See the “Monitors” topic area of Mac OS Help, available in the Help menu, for i nstructions.

Trouble with the external monitor?

Nothing happened when you tried to turn on the PowerBook.

Make sure that all your equipment is connected properly. Then try pressing the Power (π) key again.

Make sure that the battery is charged, or that the power adapter is plugged into both the computer and an electrical outlet. If you are using a power strip, make sure it is turned on.

Connecting Additional Equipment

The computer is on, but the external monitor is dark.

Make sure that the monitor’s power cord is connected and that its power switch is on. Try adjusting the monitor’s brightness and contrast settings. If this doesn’t work, try restarting your computer.

The external monitor will be dark if the PowerBook display is active and simulscan is not active. The external monitor’s resolution must be set to 800 x 600 at 60 Hz for both screens to display the computer’s image; when the external monitor is set to any other resolution, only one display is active.

Note: The screen-dimming feature in the PowerBook control panel turns the screen brightness down to a low level when you haven’t used the computer for a few minutes. (You can think of dimming as “screen sleep.”) Dimming also affects the external monitor. When you move your finger on the trackpad or press a key on the keyboard, the brightness is restored on both screens.

Disconnecting an external monitor

1 Make sure your computer is shut down or in sleep. 2 Make sure your monitor is switched off. 3 Disconnect the monitor cable (for a VGA-style monitor) or monitor adapter (for an Apple

or Apple-compatible monitor) from the external monitor port on the computer’s back panel. The port is marked with this icon:

Connecting sound input and output devices

Your computer has a built-in microphone. In addition, you ca n connect a PlainTalk microphone to the sound input port. (You can also connect a standard line-level input microphone, although it is not suitable for speech recognition.)

For information on using the microphone to record sounds, see the “Sound” topic area of Mac OS Help, available in the Help menu.

Your Macintosh PowerBook also has a stereo sound input port (on the left side of the computer’s case, marked with the √ icon) for connecting external sound input devices that provide lin e-level output. You cannot use the internal microphone and an external sound input device, such as a PlainTalk microphone, at the same time. For instructions on selecting a sound device, see the “Sound” topic area of Mac OS Help, available in the Help menu.

Microphone

Connecting Additional Equipment

IMPORTANT

Although the inter nal microphone is deactivated when an external sound input device is in use, it’s possible to record sound from more than one sound device at the same time. This can occur because the computer merges sound from devices in the expansion bay, such as an audio CD, with sound from the PC Card slots, such as a television tuner card, and from the internal expansion card slot (called PCI). If two or more devices in these locations produce sound, the sound from all of the devices may be recorded when you use the SimpleSound program or the Monitors & Sound control panel to record. To eliminate the sounds you don’t want to record, remove or turn off the device producing those sounds.

The Macintosh PowerBook also has a stereo sound output port (on the left side of the computer’s case, marked with the - icon) to which you can connect externally powered speakers, an amplifier, headphones, or other audio output devices. The sound output port accepts a standard stereo miniplug, like that used to attach headphones to a portable tape player.

Your computer also has four stereo speakers, which play sound from an audio CD in the CD-ROM drive, from an external stereo device connected to the computer through the sound in put port, from a Zoomed Video card in the lower PC Card slot, or from a file on your hard disk.

√

Sound input port

Chapter 3

You can adjust sound output quality in the Monitors & Sound control panel. (For instructions, see the “Sound” topic area of Mac OS Help, available in the Help menu.) The computer automatically selects the sound output source. If an external device, such as headphones, is connected, sound is routed there; if no external output device is connected, sound plays through the computer’s four speakers.

You can also use the Control Strip to adjust sound volume.

Connecting a mouse, keyboard, or other ADB device

You can connect a mouse, keyboard, graphics tablet, or other Apple Desktop Bus (ADB) device to the ADB port on the left side of the computer’s case, behind the PC Card slots. The ADB port has a small cover, which you open to connect the device.

IMPORTANT

You must shut down the computer or put it in sleep before

connecting an ADB device.

Connecting other devices

For instructions on connecting a device not discussed in this chapter—for example, networking hardware—refer to the manuals that came with the device.

Adding memory to your computer

Your Macintosh PowerBook comes with 32 megabytes (MB) of randomaccess memory (RAM). You can increase your computer’s memory by adding a RAM expansion card. You can find out how much memory your computer has by choosing About This Computer from the Apple (K) menu in the Finder.

You can purchase memory upgrades from Apple-authorized dealers. For complete instructions on installing a RAM expansion card, see Appendix C.

Your Macintosh PowerBook also supports virtual memory, a feature that uses hard disk space as if it were RAM. Your computer comes with virtual memory turned on. For information on using vi rtual memory, see the “Memory” topic area of Mac OS Help, available in the Help menu.

Using infrared file transfer

Your Macintosh PowerBook has built-in infrared (IR) communication features that allow you to send and receive data without wires. You can exchange files with another PowerBook or with a desktop Macintosh that is using an external IR module such as Farallon’s AirDock. In addition, you can use IR to make a wireless connection to a network by means of a specialized local area network (LAN) access device, such as Hewlett-Packard’s NetBeamIR or Extended Systems’ JetEye, that is compatible with the Infrared Data Association (IrDA) Standard specifications.

To transfer files, your computer and the other IR device must be within range of each other with the IR windows facing. The range depends on the devices and the method of communication.

Two PowerBook computers must be within 5 feet of each other to exchange files using the IRTalk tra nsfer protocol (at 230 kilobits per second). Your computer must be within 3 feet of a LAN access device or another PowerBook computer that complies with the IrDA Sta ndards to make a connection (at a transfer rate of 1 megabit per second).

You use the Infrared control panel to select the method of IR communication you want to use or to view the status of an IrDA connection. For instructions on IR file transfer, see “How do I use infrared communication?” in the “Organizing Your Files” topic area of Mac OS Help, available in the Help menu.

Chapter 3

Power sources

Your computer can draw its operating power from three sources.

Main battery

Your computer came with a lithium ion (LiIon) battery. This battery provides power for 2–4 hours of work time (you may get longer work time, depending on the Macintosh PowerBook model you have and the battery conservation features you use).

Optional battery

Your computer can also use a nickel-metal-hydride (NiMH) battery. This battery provides somewhat less work time than the LiIon battery supplied with your computer. The precise amount of work time with a NiMH battery depends on the Macintosh PowerBook model you have and the battery conservation features you use.

AC power

You can r un your computer from a grounded electrical outlet by plugging in the external power adapter that came with your computer. The installed battery will automatically be charged whenever the external AC adapter is connected. The external adapter will charge the battery more quickly if the computer is shut down or in sleep, rather than turned on or operating.

IMPORTANT

Use only the external power adapter that came with your computer (model number M4895) or one made specifically for this PowerBook model.

Power Management

Read this chapter for

information about your

Macintosh PowerBook’s battery.

In addition, the PowerBook contains a rechargeable backup cell to keep system i nformation such as date and time. T he backup cell is automatically recharged whenever the external AC adapter is connected. The backup cell also provides up to 4 minutes of power during system sleep while you change the main battery. (See “Removi ng or Replacing the Battery” later in this chapter for more information about changing batteries.)

Monitoring the battery charge

There are four ways you can determin e the charge level of your battery: m Look in the battery monitor portion of the Control Strip.

For information on the battery monitor, see the “Batteries & Power” topic area of Mac OS Help, available in the Help menu.

m See low-power messages on your display. m Look at the battery level icon next to the clock in the menu bar. m Look at the battery level indicator lights on the battery, visible when the

battery is out of the computer.

Responding to low-power messages

When the battery runs low, the computer displays a series of low-power messages. The work time remaining after you see the first message varies depending on how you are using the computer. It’s a good idea to act promptly.

What you should do

When you see a low-power message, you should do the following:

1 Plug in the power adapter, or 2 Save your work and shut down the computer, then 3 Quickly replace the empty battery with a charged one (within 30 seconds, if possible).

IMPORTANT

Always save your work when you see a low-power message.

Chapter 4

What you should know

When the first low-power message appears, the screen dims automatically to save power.

If you continue to work without plugging in the power adapter or changing the battery, the computer displays a second low-power message indicating that the computer is about to put itself to sleep. Within a few seconds, the computer goes to sleep automatically to protect the contents of RAM. All activities are interrupted. It’s a good idea to save your work when you see the first low-power message to make sure you don’t lose information.

If you continue working until the computer goes to sleep automatically, you can wake it again as soon as you plug in the power adapter or replace the battery with a charged battery.

If you can’t plug in the power adapter, the contents of RAM are retained in sleep for about a day (as long as you don’t remove the battery).

IMPORTANT

Recharge a depleted battery as soon as possible. Leaving a depleted battery in the computer for a length of time (especially in a hot location, such as the trunk of a car) may damage the battery so that it can’t be recharged. If this happens, you need to replace the battery.

Using the battery icon

There is a battery icon in the menu bar that tells you the charge left in your battery.

Power Management

The amount of black in the icon indicates the charge level. (full here)

When a lightning bolt appears in the icon, the battery is charging.

Using the battery level indicator lights (on a lithium ion batter y only)

You can tell the charge left in your LiIon battery by looking at the battery level indicator lights on the battery itself. Follow these steps to determine the charge level:

1 Save your work and then shut down the computer or plug in the power adapter. 2 Pull the battery out of its compartment.

For instructions on removing the battery, see “Removing or Replacing the Battery” later in this chapter.

3 Push the battery level indicator button to activate the battery level indicator lights.

The lights show whether the battery is fully charged, three-fourths charged, one-half charged, one-fourth charged, or empty (not shown in the illustration). A lighted square i ndicates that the battery has power; an unlighted square (black in the illustration) indicates lack of charge. T he indicator lights remain lit for a few seconds.

IMPORTANT

If the battery lights are blinking, there’s a problem with the

battery. See an Apple-authorized service provider for assistance. You can purchase a second battery from an Apple-authorized dealer, so that

you have a backup source of power when you can’t use the AC adapter.

Recharging the battery

To recharge the battery, plug in the power adapter. Your computer’s batteries may be charged inside the computer. You may also use an external battery charger designed specifically for your model of the Macintosh PowerBook.

Note: It is normal for the computer to start up when power is applied and the PowerBook has been in storage or the battery is discharged or has been removed from the computer.

A lightning bolt icon appears in the battery monitor portion of the Control Strip when the power adapter is plugged in and a battery is recharging.

The battery is recharged regardless of whether you are using the computer, or the computer is off or in sleep; however, it will recharge more quickly if the computer is off or in sleep.

WARNING

Use only the external power adapter that came with your computer or one made specifically for this PowerBook model. Adapters for other electronic devices (including other portable computers) may look similar, but they may damage your computer.

6 If you are inserting another battery, remove the battery cap from the new battery to

expose the contacts, then slide it into the battery compartment.

You cannot insert a battery if the battery cap is still on the battery. You can replace the battery with another LiIon battery. Make sure you only use a battery that is designed for your Macintosh PowerBook. You should store the battery cap in case you want to remove and transport the battery later.

IMPORTANT

If you take out the main battery while the computer is in sleep and it is not connected to an external power adapter, you must insert another battery within 30 seconds or you may lose any unsaved work.

7 If you just inserted a new battery, it’s a good idea to plug in the power adapter in case

the battery is not fully charged. You can look at the indicator lights on the battery to see the level of charge.

IMPORTANT

Lithium ion (LiIon) and nickel-metal-hydride (NiMH) batteries contain metals and other substances which are hazardous when released in the environment. It is inappropriate, and in some cases unlawful, to throw batteries away with your household or business trash. Instead of throwing away your spent batteries, dispose of them as described here

In the United States

Return spent batteries to your Apple-authorized service provider, who will make sure they are included in Apple’s battery recycling program.

Elsewhere

Many locations have government or Apple-sponsored collection or recycling programs for spent batteries. Dispose of spent batteries in accordance with the mandatory or voluntary battery collection programs in your location. Contact your Apple-authorized service provider for information about the recommended disposal procedures in your area.

Maximizing work time

Your Macintosh PowerBook’s battery can provide 2–4 hours of work time before you need to recharge. The actual work time available depends on which model of Macintosh PowerBook you have, what equipment you’re using with your computer, and what steps you take to conserve power while you work.

Some battery-saving measures you can take include the following:

m Minimize backlighting of the display. m Turn off AppleTalk if your PowerBook is not connected to a network. m Set the hard disk to spin down after a very short interval. m Remove PC Cards and CDs when they are not in use. m Take advantage of the sleep feature of your PowerBook whenever your

work is interrupted (such as when the cellular phone rings). You just need to close the display to put the computer in sleep.

8) “freezing” on the screen. If you have trouble with your computer, take a few minutes to read the information in this chapter and Chapter 6. If your problem is related to a particular procedure, you should also look for information on that procedure in Mac OS Help, available in the Help menu. If you are unable to access Mac OS Help (for example, if your screen is “frozen”), refer to this chapter to see if you can resolve the problem.

This chapter and Chapter 6 describe solutions to problems you may experience with your computer. If the suggestions in these two chapters don’t solve your problem, contact a local Apple-authorized service provider or call the Apple Assistance Center. (See the service and support information that came with your computer for the telephone numb er.) If your problem is with third-party software or equipment, please call the software or equipment manufacturer for help.

Tips and Troubleshooting

Consult this chapter if you have

questions or experience

problems using your computer.

Problems starting up the computer

The computer doesn’t start up.

m The battery may need recharging. Plug the power cord into a working

outlet and then plug the power adapter into the computer. Let the battery recharge for a few minutes.

m Check that the power cord is plugged into a working outlet. If it’s plugged

into a power strip, make sure the power strip is turn ed on. Th e power adapter should get warm after being plugged in for 10 mi nutes. If it is cold, make sure the adapter is securely plugged in a nd attached to the power cord.

m The screen brightness may be turned down. Adjust the brightness control

(marked with the icon ¤) located above the top row of keys on the keyboard, to the right of center.

m Make sure the battery is properly seated in its compartment. m If none of these measures helps, you may need to reset the computer. T h e

method of resetting you should always try first is to press the Command (x), Control, and Power keys simultaneously. If the computer does not start up, connect the power adapter (if it is not already connected) and press the reset button (marked with the icon I) on the back panel.

m If the reset described in the previous paragraph does not start up the

computer, remove the battery and unplug the power adapter and hold in the reset button for 30 seconds. Then reconnect the power adapter and put in the battery and try starting up again.

Reset button

Chapter 5

The sleep indicator light at the top of the display glows a steady green.

You must reset the computer using the reset button. Connect the external power adapter (if it is not already connected) and press the reset button (marked with the icon I) on the back panel.

When the reset procedure is used the computer will thoroughly test the RAM, so it may take a few moments (about 1 second per megabyte of RAM) before the screen lights. Be patient if you have added expansion RAM.

The computer makes an unusual sound at startup, or you see a “sad Macintosh” icon.

m If you hear the sound of breaking glass when you turn on the computer or

you see a “sad Macintosh” icon, start up the computer with the PowerBook CD that came with your computer. If the computer does not start up, or if the hard disk icon does not appear, the hard disk may n eed repair. Contact an Apple-authorized service provider or call the Apple Assistance Center. If the hard disk icon does appear, see Chapter 6 for information about reinstalling the system software.

m There may be a problem with the information stored in the area called

parameter RAM (PRAM). Reset the PRAM (also called “zapping the PRAM”).

Resetting the PRAM erases the contents of your RAM disk, if you have one. Resetting the PRAM also restores the default settings in most control panels. After you reset the PRAM, be sure to check any custom settings you made for the desktop pattern, memory, network, AppleTalk, trackpad, power conservation, and so forth. Resetting the PRAM also resets the power manager.

Follow these steps to reset the PRAM:

1. Locate the keys Command (x), Option, P, and R.

2. Make sure the Caps Lock key is not down.

3. Restart your Macintosh (using the Command [x], Control, and Power keys or the reset button, if necessary). Immediately after hearing the startup sound, press the Command (x), Option, P, and R keys simultaneously.

If you don’t hold down the key combination within 5–10 seconds after you restart, you may need to repeat steps 1–3.

4. Hold down the keys until you hear the startup sound again.

Tips and Troubleshooting

5. If the computer shuts itself off, press the Power key to turn it back on.

6. When the computer has finished starting up, restore any custom control panel and network settings.

m If nothing happens after you reset the PRAM, there may be a problem with

a RAM expansion card. If you installed a RAM expansion card in your computer, check Appendix C to make sure the card is properly installed. If you purchased an expansion card from a third-party manufacturer, contact the manufacturer for help.

See also “The Computer Makes Unusual Sounds” in the section “Other Problems While Working” later in this chapter.

The computer starts up, but the desktop doesn’t appear.

m The screen brightness may be tur n ed down. Adjust the brightness control

(¤), located above the top ro w of keys on t he k eyboard, to the ri ght of center.

m The computer may be trying to start up using an external hard disk that

does not contain the correct system software. Disconnect the external hard disk and restart your computer. (This can also happen with PC Card drives and expansion bay drives.)

m Start up the computer, holding down the Shift key until you see the

message “Extensions off” in the “Welcome to Macintosh” box. If the computer starts up, turn to Chapter 6 and try the steps given in the section “Checking Your System Software Extensions.” You can go directly to the Extensions Manager control panel by holding down the Space bar during startup.

When you start up the computer, you see a message about the system software.

m The system software on the startup disk you’re using may be incomplete or

damaged, or may be the wrong version. Make sure you’re using the correct disk as a startup disk. (You can start up from the CD that came with your computer by pressing the letter “c” as the computer starts up.)

m If you’re sure you’re using the correct startup disk, you may need to

reinstall system software. See “Reinstalling System Software” in Chapter 6.

Chapter 5

The computer displays a flashing question mark icon.

m This icon usually means that the computer can’t find system software on

any disks attached to the computer. If the computer is connected to any external hard disks, make sure they are turned on. Then restart the computer. If the problem recurs, the hard disk or its system software may be damaged. See Chapter 6.

m Turn off the computer, disconnect all external devices except the power

adapter, and restart the computer. If the computer starts up, turn to “Problems with Equipment Connected to Your Computer ” later in this chapter.

The computer freezes or displays an error message during startup.

m Tur n off the computer, disconnect all external devices except the power

adapter, and restart the computer. If the computer starts up, turn to “Problems with Equipment Connected to Your Computer” later in this chapter.

m Start up the computer, holding down the Shift key until you see the

message “Extensions off” in the “Welcome to Macintosh” box. If the computer starts up, turn to Chapter 6.

About the codes in error messages: The number codes in error messages are used in software development. Sometimes they can help a technician narrow down the source of a problem. However, the codes are usually too general or technical in nature to help you diagnose a problem yourself.

When the computer starts up, a message says there is not enough memory.

There may not be enough memory to load all the system software extensions you’ve installed. Restart the computer, holding down the Shift key until you see the message “Extensions off” in the “Welcome to Macintosh” box. Then try the following to increase available memory:

m Turn on virtual memory in the Memory control panel, or increase the

virtual memory size if it’s already on. Your PowerBook can deliver good performance with virtual memory set to two to three times the amount of actual RAM in the computer.

Tips and Troubleshooting

m Reduce the size of the disk cache in the Memory control panel. m If you use a RAM disk, reduce its size or turn it off in the Memory

control panel.

m Use the Extensions Manager control panel (in the Control Panels folder

inside the System Folder on your hard disk) to turn off extensions you don’t need. Then restart the computer. (You can use Extensions Manager to

create different sets of extensions for special situations.) You n eed to restart the computer for these changes to take effect. If these suggestions don’t work, you can increase memory by installing a

RAM expansion card in your computer. See Appendix C for information.

The computer won’t restart.

m If the computer freezes, you can try to “force” the program you’re using

to quit by simultaneously pressing the keys Command (x), Option, and

Esc on your keyboard. Then click Force Quit in the dialog box that

appears. (Note: Unsaved changes in your current documents will be

lost.) Immediately save all open documents, quit all other open programs,

and restart the computer. m You may need to reset the computer. The method of resetting you should

always try first is to press the Command (x), Control, and Power keys

simultaneously. If the computer does not start up, connect the power

adapter (if it is not already connected) and press the reset button (marked

with the icon I) on the back panel.

Note: You will lose any work you have not saved. m If the problem recurs, reset the parameter RAM (see “The Computer

Makes an Unusual Sound at Startup, or You See a ‘Sad Macintosh’ Icon,” in

the section “Problems Starting Up the Computer” earlier in this chapter). If

the problem still occurs, see Chapter 6.

Every time the computer starts up, it rebuilds the desktop.

There may be a folder on your hard disk that has the same name as a file the computer uses to keep track of information on your disks. Manually search for a folder named “Desktop” or “Desktop file.” If you find on e, rename it “Storage.” Then restart the computer. (Do not use the Find File feature to search for the desktop file. It may find it but you may not be able to access it.)

Chapter 5

When you start up the computer, the display lights up for a moment, then shuts down.

m Make sure you are using the correct power adapter for your

computer model.

m If the computer is running on the battery, make sure the battery is charged.

Or connect the external power adapter.

The computer won’t wake after the battery was replaced with the computer in sleep and without the power adapter plugged in.

m Connect the power adapter and press the Power key (or any other key

except Caps Lock) to wake the computer. Tip: Leave the power adapter plugged in and charging the system for at

least 24 hours to ensure that the backup battery is charged enough to allow battery replacement during computer sleep.

Problems working with programs

The computer freezes or displays a system error message.

m There may be a temporary software problem. To reset the computer, try the

following suggestions in order until the computer starts up normally:

1. If the computer freezes, you can try to quit the program you’re using by pressing the keys Command (x), Option, and Esc on your keyboard. Click Force Quit in the dialog box that appears. (You’ll lose unsaved changes in that program’s do cuments.)

Immediately save all open documents and quit all op en programs, then restart the computer.

2. If you see a message about a system error, you may need to reset the computer. T he method of resetting you should always try first is to press the Command (x), Control, and Power keys simultaneously. If the computer does not start up, connect the power adapter (if it is not already connected) and press the reset button (marked with the icon I) on the back panel.

Note: You will lose any work you have not saved.

Tips and Troubleshooting

3. Reset the PRAM (see “The Computer Makes an Unusual Sound at Startup, or You See a ‘Sad Macintosh’ Icon,” in the section “Problems Starting Up the Computer” earlier in this chapter for instructions).

m If the problem recurs, it may involve one or more of your application

programs. See “The Computer Exhibits Odd Behavior, Such as Many Unexplained System Failures,” next.

The computer exhibits odd behavior, such as many unexplained system failures.

m Check for multiple System Folders on your startup disk, using the Find File

command. Throw away extra System Folders (but do not throw away any System Folders from your RAM Disk Backup folder). The System Folder that your computer is using has a Mac OS logo on it.

m Check for viruses on all your disks, using a vi rus-detection program.

Eliminate any viruses the program finds.

m If a problem recurs when you are using a particular program, try

the following: m Consult the documentation that came with the program to make sure you

are using it correctly.

m Check for multiple copies of the program on your hard disk. Use the Get

Info command to check the programs’ version numbers. Keep one copy of the latest version and throw away all other copies.

m Reinstall the program from a known good source (such as the original

program disks or the CD that came with your computer).

m Increase the program’s memory. Quit the program, select its icon, choose

Get Info from the File menu, and type a larger number in the Preferred Size box.

Chapter 5

m Contact the manufacturer or vendor of the program to find out whether

the program contains software er rors or “bugs” and whether an upgrade is available.

m Check that the program is compatible with the version of system

software your computer is using. (See the program’s documentation, or contact the manufacturer or vendor.) You can find out which version of software you have by c hoos in g A bout This Computer in the Apple (K) menu.

m Make sure your control panels and system software extensions

(especially a ny that you recently added) are compatible with your programs. See Chapter 6.

A program won’t open.

m The application program may already be open. Check the Application

menu to see which programs are running.

m There may not be enough memory available to open the program. Quit any

programs you’re not using and try again. If that doesn’t work, try restarting the computer.

m If the program is on a floppy disk, make sure the disk is unlocked. (You

unlock a disk by sliding the tab at the corner of the disk so that it covers the hole.)

m The program may be damaged, or it may not be compatible with PowerPC

technology. Check to make sure the software is PowerPC-compatible, and install it from a known good source (such as the original program disks).

m Contact the manufacturer or vendor of the program to see if the program is

compatible with the version of system software your computer is using. (Choose About This Computer from the Apple [K] menu to see which version of system software you have.)

A program suddenly quits or disappears, or a message says a program has quit.

m There may be a temporary software problem. Restar t the computer, then

try opening the program again.

m The program may have run out of memory. See the suggestions in

“A Message Says There Is Not Enough Memory,” next.

m If the problem occurs when you are trying to print, there may not be

enough memory for pri nting.

Tips and Troubleshooting

m Contact the manufacturer or vendor of the program to see if the program

contains software errors or “bugs” and if it is compatible with the version of system software you’re using.

A message says there is not enough memory.

m There may be a temporary software problem. Save your work, quit all open

programs, a nd restart the computer. If you can’t use the Restart command, see the suggestions in “Th e Computer Freezes or Displays a System Error Message,” earlier in this section.

m If you get this message when you are trying to open or use a program,

follow these steps:

1. Choose About This Computer from the Apple (K) menu. Take note of the number in the Largest Unused Block section. This number tells you how much memory is available to open programs.

2. Quit the program if it’s open, select its icon, and choose Get Info from the File menu. Take note of the numbers in the Minimum Size and Preferred Size boxes.

3. If the number in the Minimum Size box is larger than the largest unused block, not enough memory is available to use this program. To free memory, quit open programs or restart the computer. You can also type a smaller number in the Minimum Size box if you want to open the program using less memory. (But some programs don’t work well if you assign them less memory.)

4. If the number in the Preferred Size box is smaller than the largest unused block, you may n eed to assign more memory to the program. (A program may need more memory if you are working with complex documents.) Type a larger number in the Preferred Size box.

m If you frequently want to open more programs than memory allows, try

the following: m Turn on virtual memory in the Memory control panel or increase the

amount of virtual memory if it is already on.

m Use the Memory control panel to reduce the size of the disk cache or

remove or reduce the size of your RAM disk.

m Install a RAM expansion card in your computer. See Appendix C

for instructions.

Chapter 5

When you try to open a document, a message says the program can’t be found.

m The document may have been created with a program that is not on your

hard disk, or with a different version of the program.

m You can also open a document from within a program by using the Open

command in the File menu. For more information, see the documentation that came with your programs.

m If you know the correct program is on your hard disk, there may be a

problem with the information that the computer uses to keep track of files. Restart the computer and hold down the Command (x) and Option keys until you see a message asking if you want to rebuild the desktop. Release the keys and click OK.

Note: If you have Macintosh Easy Open installed, you must use the Extensions Manager control panel to turn off all extensions except the Macintosh Easy Open control panel, and then follow the previous steps to rebuild your desktop.

A window has disappeared.

m Another open window may be covering the one you’re looking for. Move,

resize, close, or hide windows until you see the one you wa nt.

m The program the window is associated with may be hidden. Choose Show

All from the Application menu, then click the window you wa nt, or choose the program from the Application menu.

Problems with hardware

RAM or cache diagnostic error

You see a message that a problem was detected with RAM or cache memory.

If you see this type of error message, take your computer to a n Appleauthorized service provider. Ignoring this condition could lead to random errors and failure that could result in your losing data. (Although the error message may not reappear, the problem detected during the computer’s selfcheck probably has not gone away.)

Floppy disk drive

You can’t eject a floppy disk.

The disk may be stuck. Restart the computer, holding down the trackpad button. If the disk is not ejected, you ca n eject it manually. Carefully i nsert the end of a straightened paper clip into the small hole near the disk drive’s opening, and push firmly until the disk is ejected.

not be recognizing the disk. See “Problems With Equipment Connected to Your Computer,” later in this chapter.

m There may be a problem with your startup disk or with its system software.

See “Testing Your Hard Disk” in Chapter 6.

Trackpad

The pointer won’t move.

m A program may be doing some work. Wait a few moments and then

try again.

m A temporary software problem may have caused the computer to “freeze.”

See “The Computer Freezes or Displays a System Error Message” in the section “Problems Working With Programs,” earlier in this chapter.

Tips and Troubleshooting

The pointer sticks or jumps when you use the trackpad.

Make sure to use only on e finger on the pad and that your finger is dry.

Keyboard

Typing on the keyboard produces nothing on the screen.

m Make sure the program you’re using is set to accept text input. Usually you

need to set an insertion point or select some text before typing. If you’re using a communications program, you may need to turn on the “local echo” setting.

m Open the Easy Access control panel and make sure Slow Keys is

turned off.

m Open Key Caps in the Apple (K) menu and check whether the computer is

recognizing keyboard input. If so, the keys in the Key Caps window will indicate when keys are pressed on the keyboard.

A key won’t stop repeating.

Open Key Caps in the Apple (K) menu. If any keys in the window are darkened, keys may b e stuck down on your keyboard.

PowerBook display

The screen went blank.

m Screen dimming may be on. Move the pointer to restore the

screen’s brightness.

m The computer may have gone to sleep. Press any key (except Caps Lock)

on the keyboard to wake it.

m The battery may need recharging. Plug in the power adapter, let the

battery charge for a few minutes, and then try to wake or start up the computer again.

m If an external monitor is connected, the image may be displayed on that

monitor and not on the PowerBook’s display. (If the external monitor is set to a different resolution from the 800 x 600 pixels of the PowerBook display, the computer’s image only app ears on the external monitor.)

Chapter 5

The screen flickers.

m Adjust the brightness control (¤). m Open the Monitors & Sound control panel or use the Control Strip to set

the computer to display fewer colors or grays.

m If tilting the display affects the flickering, there may be a loose cable.

Contact an Apple-authorized service provider, or call the Apple Assistance Center at the number provided in the resource materials that came with your computer.

The computer freezes when screen dimming takes effect.

Screen dimming does not work with some programs. Contact the program’s manufacturer to see if there is a newer version of the program that is compatible with dimming. If the problem persists, you can open the PowerBook control panel and turn off screen dimming.

External monitors

The monitor remains dark.

Shut down the PowerBook, then make sure the monitor is connected to the PowerBook, plugged into an active outlet, and turned on. (Most monitors have a light on the front panel to show whether they are on.)

The monitor is on, but no image appears.

m Use the Monitors & Sound control panel to select a resolution that will

display on the external monitor. If the resolution is not 800 x 600 at 6 0 Hz, the PowerBook’s screen goes blank when the external monitor is in use.

m Screen dimming may be on. Move the pointer to restore the

screen’s brightness.

m Adjust the monitor’s brightness and contrast controls. m Use the Control Strip to change the resolution on the external monitor. If

you still don’t see an image, there may be a problem with the monitor.

m If you are using an Apple monitor with a 15-pin connector, be sure that the

video adapter that came with your computer is connected (between the monitor cable and the PowerBook’s external monitor port).

Tips and Troubleshooting

The monitor goes dark after a few minutes.

Screen dimming may be tur n ed on. Move the pointer to restore the screen’s brightness. You can change the interval before screen dimmi ng takes effect in the PowerBook control panel.

The computer freezes when screen dimming takes effect.

There is wavy or jittery interference on the external monitor.

This interference may be generated by a magnetic field. If the monitor is near another piece of equipment (such as a TV, speakers, or another monitor), move the monitor away from the equipment.

You connected a different external monitor and it turns on but doesn’t display an image.

Once you set the resolution for an external monitor, any other external monitor subsequently connected to your PowerBook will attempt to use that resolution. If you cannot set a resolution for the new external monitor that results in an image on the screen, you may need to detach the second monitor, discard the Display Preferences file (in the Preferences folder inside the System Folder), reconnect that monitor, and choose a resolution over again to see a satisfactory image. For instructions, see the Monitors topic area of Mac OS Help, available in the Help menu.)

Printers

The computer can’t find the printer.

m Make sure the printer is connected and turned on.

IMPORTANT

Make sure that all equipment is turned off before connecting or

disconnecting cables. m The printer may not be selected in the Chooser. Open the Chooser and

select the printer you want to use. If the printer is connected to a port, make sure the correct port is selected.

Chapter 5

m Reset the parameter RAM. (See “The Computer Makes an Unusual Sound

at Startup, or You See a ‘Sad Macintosh’ Icon,” in the section “Problems Starting Up the Computer” earlier in this chapter for instructions.) Then select the printer in the Chooser and try printing again.

The printer does not appear in the Chooser.

m Make sure you’ve selected the correct kind of printer on the left side of the

Chooser window. For example, if you’re using a StyleWriter II, make sure to select StyleWriter II, not StyleWriter.

m Use the scroll bars to look through all the selections in the Chooser windows. m Check the connections between your computer and the printer, including

relevant sections of the network if appropriate. (See “Problems With Networks and File Sharing” later in this chapter.)

m Make sure the correct printer software is in the Extensions folder inside

your System Folder.

m If you’re using a network printer, make sure that AppleTalk is active in the

Chooser. If you are using a printer connected directly to your computer, make sure AppleTalk is inactive, or the Printer/Exter nal modem port is not selected in the AppleTalk control panel.

m If your network has zones, make sure the zone containing your printer

is selected.

Nothing happens, or an error message appears, when you try to print.

m There may not be enough memory for printing. Try the following:

m Quit the program immediately after sending the Print command. m Increase the amount of memory that Desktop PrintMonitor uses. (Locate

Desktop PrintMonitor in the System Folder, select it, choose Get Info from the File menu, and type a larger number in the Preferred Size box.)

m Reduce the amount of memory the program uses.

m Make sure the printer is turned on. Some printers need to warm up for a

few minutes after you turn them on.

m The printer may be out of paper or may need attention. Check the printer

status lights and any messages on your screen.

m Open the current printer (its icon has a bold outline) and check for

status messages.

Tips and Troubleshooting

m Reinstall your printer software. m Reset the parameter RAM. (See “The Computer Makes an Unusual Sound

m You may not be able to use password protection with your PowerBook in

SCSI disk mode. Turn password protection off in the Password Security control panel.

m Check that all cables are connected securely, that the devices are plugged

into working outlets, and that the devices are turned on.

IMPORTANT

Make sure that all equipment is turned off before connecting or

disconnecting cables. m Make sure that you turn on SCSI equipment before you start up the

PowerBook.

m Check that each connected SCSI device has a unique ID number

between 0 and 6.

m Make sure that SCSI cable terminators are correctly positioned. Follow the

instructions in “Connecting SCSI Devices” in Chapter 3.

You can’t turn on the computer after connecting a SCSI device.

m Tur n on the SCSI equipment first, and then turn on the computer. m Try disconnecting the SCSI equipment to determine if the computer will

start up. If not, see the beginning of this chapter.

When you start up using SCSI disk mode, the desktop appears.

When you use SCSI disk mode, the computer should display an icon with a number in it.

Chapter 5

If the computer starts up normally, immediately press the Power key to shut down (if you can) or tur n off the computer. If you don’t, you might damage your information or equipment.

m Make sure you are using the correct cable for SCSI disk mode. The HDI-30

SCSI Disk Adapter is about 10 i nches long, is dark gray, and has 30 pins in the connector (no “missing” pins). Do not use the HDI-30 SCSI System Cable, which is light gray, is about 19 inches long, and has 29 pins in the connector (one “missing” pin). That cable is for connecting SCSI equipment to your PowerBook.

m Check that all cable connections are secure. m The PowerBook’s battery may be drained. Plug in the power adapter and

let the battery charge for a few minutes. Then press the Power key on the PowerBook’s keyboard to restart it, and restart the other Macintosh.

m Start up the other Macintosh with the CD or Disk Tools floppy disk that

came with it (do not use the CD that came with your PowerBook). If the connection works, then a system software extension on the other Macintosh may be causing the problem.

When you start up using SCSI disk mode, you see a flashing question mark icon.

m Make sure you are using the correct cable for SCSI disk mode. The HDI-30

SCSI Disk Adapter is about 10 i nches long, is dark gray, and has 30 pins in the connector (no “missing” pins). Do not use the longer, light gray HDI-30 SCSI System Cable.

m Make sure terminators are placed correctly in the SCSI chain. For more

information, see “Connecting SCSI Devices” in Chapter 3.

The Macintosh you are connected to in SCSI disk mode doesn’t see the PowerBook.

m You cannot use the PowerBook in SCSI disk mode if password protection

is turned on. Turn password protection off in the Password Security control panel.

Tips and Troubleshooting

m Make sure you are using the correct cable for SCSI disk mode. The HDI-30

SCSI Disk Adapter is about 10 i nches long, is dark gray, and has 30 pins in the connector (no “missing” pins). Do not use the longer, light gray HDI-30 SCSI System Cable.

m Make sure terminators are placed correctly in the SCSI chain. For more

information, see “Connecting SCSI Devices” in Chapter 3.

m Check that there is no conflict between SCSI ID numbers among all

devices in the SCSI chain. If necessary, you can change the ID for your computer in the PowerBook control panel.

m Start up the other Macintosh with the CD or Disk Tools floppy disk that

came with it (do not use the CD that came with your PowerBook). If the connection works, then a system software extension on the other Macintosh may be causing the problem.

Problems with equipment connected to your computer

If a problem occurs while your Macintosh PowerBook is connected to equipment such as SCSI equipment, an external monitor, a modem, a pri nter, a mouse, or a keyboard, these steps may help you determine the source of the trouble:

1 Shut down or turn off your Macintosh PowerBook and anything that’s connected to it.

Disconnect everything connected to your Macintosh PowerBook (except the power adapter) and restart it.

Note: If you’re connected to a network, contact your network administrator or warn other users before disconnecting from the network, because it may interrupt network services.

If the problem does not recur, it is likely related to equipment connected to your PowerBook.

2 Shut down the Macintosh PowerBook. 3 Reconnect one device. 4 Make sure that the device is plugged into a working outlet and turned on, if applicable. 5 Start up the Macintosh PowerBook. 6 Repeat steps 2–5 until the problem recurs. The last device you connected may be

causing the problem.

Chapter 5

Problems with networks and file sharing

Solutions to common problems

If you are having problems using the network or file sharing, try the following before attempting further solutions:

m Make sure that AppleTalk is turned on i n the Chooser. m Open the AppleTalk or TCP/IP control panel and make sure the correct

network connection is selected.

m Whenever you make a change in the AppleTalk or TCP/IP control panel,

be sure to close that control panel so that the change takes effect.

m Make sure that all the network software is installed. If you aren’t certain

that all networking software is installed, you can use the Custom option of the Installer program on the CD that came with your computer to reinstall all network software.

m Make sure the network is working by opening the Chooser and checking

for the shared disks and printers you usually use.

m Try connecting to the network from a different location, or connecting a

printer or another computer directly to the PowerBook using network cables. If that works, the problem is likely to be in the network. If it doesn’t work, the problem may be in the PowerBook or its network software.

Solutions to other problems

The computer you want to connect to doesn’t appear in the Chooser.

m Make sure the computer you’re trying to connect to is turned on. m Make sure file sharing is active on the computer you’re trying to connect to.

(That computer’s File Sharing control panel should say that file sharing is on.)

You connected to another computer, but the shared disk you want to use is not available.

m You may already be connected to the shared disk. Check for its icon on

your desktop.

m You may not have the access privileges you need to use the shared disk.

Ask the network administrator or the owner of the shared item to give you access. (See the “Sharing Files” topic area of Mac OS Help, available in the Help menu.)

Tips and Troubleshooting

Tips and Troubleshooting

Problems with Apple Remote Access

The Remote Access Setup control panel won’t open.

m Make sure that AppleTal k is turned on in the Chooser. m If you still can’t open the control panel, reinstall the Apple Remote

Access software.

The modem is not listed in the Remote Access Setup control panel.

m Reinstall the modem software. If that doesn’t help, then reinstall the Apple

Remote Access software.

m If you are using a PC Card modem, make sure the modem file for your

modem is in the Modem Scripts folder inside the Extensions folder (in the System Folder). If it is not, check the software that came with your modem. If you locate a file for your modem, put it in the Modem Scripts folder.

m Contact the modem manufacturer to see whether your modem can use the

settings for a nother type of modem.

The modem didn’t dial the phone number.

m Check that the phone cord is plugged into the computer and into a working

phone line.

m Try dialing the number again. Sometimes there is a temporary

connection problem.

m Quit the program and restart it. Sometimes this procedure solves

temporary problems with the modem.

m Another program may be using the modem. Quit all other programs that

use the modem.

m Try using another communications program. If that works, the problem

may be in the Apple Remote Access software. Reinstall the software.

Chapter 5

The modem dialed the phone number, but the connection failed.

Tips and Troubleshooting

This chapter provides a step-by-step approach to diagnosing and solving problems involving system software and hard disks. Try the steps listed in each section in the order they are given until your problems are fixed.

Checking your system software extensions

System software extensions are files that add features to your system software. Some extensions are incompatible with one another or with certain programs. To check whether an extension is causing problems, follow these steps:

1 Start up the Macintosh PowerBook while holding down the Shift key. Keep it held down

until you see the message “Extensions off” in the “Welcome to Macintosh” box.

This procedure tur ns off extensions. If this procedure solves your problem, then continue with this section. If not,

then turn to the next section, “Testing Your Hard Disk.”

Diagnostic Techniques

Consult this chapter before you

call the Apple Assistance Center

to solve problems with system

software and your hard disk.

2 Restart the computer while holding down the keys Command (

), Option, P, and R until

you hear the startup sound repeat itself three times. Then release the keys.

This procedure resets the parameter RAM. For more information, see “The Computer Makes an Unusual Sound at Startup, or You See a ‘Sad Macintosh’ Icon,” in the section “Problems Starting Up the Computer” in Chapter 5.

If the problem does not recur, it may involve file sharing, virtual memory, or the disk cache. Turn these features back on one at a time (restarting the computer each time) until the problem recurs. You may be able to fix the problem by making the disk cache smaller or using a smaller amount of virtual memory. If the problem involves file sharing, contact your network administrator to make sure there are no network problems.

3 Turn off troublesome extensions using the Extensions Manager control panel.

Tips for locating problem extensions: m If you recently installed a new item in the System Folder, it may b e causing

the problem. If you recently installed a new application program, a new extension may have been installed along with it. Check for new items in the Extensions folder and Control Panels folder. Also check for items of the kind “extension” or “control panel” in the System Folder itself.

m If two of your extensions provide similar features (such as two screen

savers or two clocks), they may be incompatible with each other. Remove one of the extensions.

m If the computer is freezing or displaying an error message before it finishes

starting up, restart the computer and take note of the icons that appear at the bottom of the screen. Many extensions display a n icon as they start up, and extensions start up alphabetically. The last extension that displays an icon, or the one after it alphabetically, may be the problem extension.

4 Turn extensions back on, one extension at a time, in the Extensions Manager control

panel. Restart the computer after turning on each extension and test to see if the problem recurs.

When you have located the problem extension, remove it from the System Folder and contact the developer or vendor for compatibility information.

5 Go to the next section if you are still having problems.

Chapter 6

Testing your hard disk

The following steps will help you determine whether you have a problem with your hard disk or a problem with the system software on your hard disk.

1 Start up the Macintosh PowerBook with the system software CD that came with your computer.

If the computer starts up normally, you may have a problem with the system software on your hard disk. If the computer starts up but you don’t see the hard disk icon, you may have a problem with the hard disk.

If the computer doesn’t start up normally, you may have a problem with equipment connected to your Macintosh PowerBook. See “Problems With Equipment Connected to Your Computer” in Chapter 5.

If nothing is connected, your computer may n eed repair. Contact an Appleauthorized service provider, or call the Apple Assistance Center.

2 Open the Drive Setup icon.

You may need to look in a folder called Utilities to find Drive Setup.

Note: You can get onscreen help using the Drive Setup application program by choosing the Drive Setup Guide, available in the Help menu when Drive Setup is runni ng.

3 In the list of drives, click the disk you want to test.

Diagnostic Techniques

4 Open the Functions menu and choose Test Drive. 5 When a message tells you that testing is complete, click Quit.

If you cannot repair the disk, you may need to reinitialize the disk using the Drive Setup program.

6 If testing indicates that no repair is necessary, but you’re still having a problem with your

computer, go to the next section.

Reinstalling system software

When should you install system software?

Your computer came with all the necessary system software installed on its internal hard disk, so you don’t need to install system software on that disk unless you encounter software problems.

If you have a new hard disk or a newly i nitialized hard disk that doesn’t contain system software, or if you want to upgrade to a more recent version of system software on a hard disk, follow the instructions in “Installing Mac OS 8” later in this chapter.

If you have a problem with your system software, you may see this icon in the middle of the screen:

If this icon appears, follow the instr uctions in “Testing Your Hard Disk” earlier in this chapter to test your startup hard disk a nd repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing Mac OS 8” to reinstall system software on your startup hard disk.

WARNING

Reinitializing the hard disk erases all the information on it. If you don’t have a recent backup of your information, an Appleauthorized service provider may be able to recover some of the information before you reinitialize the hard disk.

Chapter 6

Restoring custom settings and special software

Your computer came from the factory with

m additional applications m system software settings m the Mac OS Info Center customized for your computer

When you reinstall system software using the Mac OS 8 Install program described in this chapter, it will not reinstall bundled applications, reset customized settings, or provide customized information about your computer.

If you want to restore your computer to its custom settings, use the restore program that is included on your system software CD. Follow these steps:

1 Restart your computer using your system software or restore CD, as described in the

next section.

2 Follow the instructions in the Read Me file for more information about restoring your

system software or bundled applications.

Diagnostic Techniques

Using a CD to start up your computer

Before you reinstall software onto your hard disk, you need to start up your computer with the CD-ROM containing system software. This allows the Mac OS Install program to repair any problems on your hard disk and update the disk driver before you install the software.

Before you begin the installation, do the following: m Turn off any virus-protection software and disk-security software you

may have.

m Plug in the power adapter and set the computer so it doesn’t go to sleep. m Turn off password protection in the Password Security control panel.

Follow these steps to start up from the CD containing system software.

1 Press the Open/Close button of your CD-ROM drive to open the CD-ROM tray. 2 Place the CD-ROM disc containing system software in the tray with the disc label

facing up.

Make sure the disc is lying flat in the tray.

3 Close the CD-ROM tray by pushing in the tray or pressing the Open/Close button. 4 Hold down the C key on your keyboard while you choose Restart from the Special menu

and wait for the message “Welcome to Mac OS” to appear.

5 When you see the screen that says “Mac OS” and the phrase “Starting Up,” release the

C key.

In a few seconds the desktop appears. Your computer is now using the system software that’s on the CD-ROM disc. You’ll know you’ve started up from the CD-ROM disc if you see the CD-ROM disc icon at the top-right corner of the desktop, above your hard disk icon. The desktop pattern will also be different.

Chapter 6

Installing Mac OS 8

After you’ve started up your computer using the CD-ROM disc, use the Mac OS Install program to install the software.

1 Double-click the Mac OS Install icon.

After a moment, a screen appears describing the four steps in the installation process.

The Mac OS Install program guides you through the steps necessary to install the software. To learn more about each step, click the Help (h) button in the upper-right corner of the window.

Diagnostic Techniques

Click to display more information about each step.

2 When you’re ready to begin, click Continue and follow the instructions you see on the screen.

Note: The Mac OS Install program automatically runs the applications Drive Setup and Disk First Aid before starting the installation process. Prior versions of system software required that you run these applications separately. If you need information on how to use these applications, choose Drive Setup Guide or Disk First Aid Guide when each application is running.

As part of the normal software installation process, the Mac OS Install program replaces changed system files and adds new ones, but leaves others alone. In addition, the Mac OS Install program provides an option for doing a clean installation of system software.

IMPORTANT

You should only perform a clean installation if you have already tried reinstalling system software as described in this section and are still experiencing the same problems with your system. For more information on when you should do a clean installation, see “Performing a Clean Installation” later in this chapter.

Responding to messages about your hard disk

The Mac OS Install program checks the destination hard disk for errors before installing the software. If your hard disk was formatted with an Apple disk utility program, the Installer updates the hard disk drivers with the latest version of the driver software. If your disk was formatted with a disk utility from another company, the drivers are not updated. You should use the third-party disk utility to update your hard disk before installing Mac OS 8.

Chapter 6

Selecting which software to install

The Mac OS Install program installs the basic components of the system software along with additional software features such as QuickDraw 3D and Personal Web Sharing.

After you select a drive for installation, you will see these choices: m Reinstall Mac OS 8

Select this option if you n eed to reinstall system software to solve system software problems or repair a damaged hard disk. This process is known as a standard installation. If you select this option, go to the next section, “Select Software to Install Using a Standard Installation.”

m Add or remove software features

Select this option if you want to install specific components of Mac OS 8 or additional software features. You can also use this option to selectively remove software components. This process is known as a custom installation. If you select this option, skip ahead to the section “Select Software to Install or Remove Using a Custom Installation.”

For most computer users, the standard installation is best, because it automatically installs everything you need for your model of computer. However, if you’d like to select only the software specific to your needs, you can customize your installation. You can install or update one or more specific f iles, or sa ve space on your hard disk by installing only t he files you want.

Diagnostic Techniques

Select software to install using a standard installation

The next step in the installation process is to select the software that you want to install along with Mac OS 8.

1 Select the software to install along with Mac OS 8.

The Install Mac OS 8 window provides a list of items that you can select or deselect. Boxes that are already selected are those items that are normally installed as part of the Mac OS.

2 Click Start.

Mac OS 8 along with any additional software you selected is now installed on your computer.

3 After you’ve installed all the software you selected, restart your computer.

Chapter 6

Select software to install or remove using a custom installation

The next step in the installation process is to select the software that you want to install along with Mac OS 8.

1 Select the software to install, the software to remove, or both.

As you proceed in the custom installation process, you’ll be able to determin e exactly which c omponents will be installed or removed for t he software you select.

When performing a custom installation you ca n choose whether to install Mac OS 8. If you select Mac OS 8, you will be able to add or remove specific components of Mac OS 8, such as fonts and printer drivers.

2 Click Start.

The Installer for the first software product you selected appears. You’ll use the Installer to specify which components of the product you want to install.

3 When you see the Installer’s welcome screen, click Continue.

If you want all the recommended components for this product, click Install. Then skip to step 8.

If you want to install sp ecific components of the software, or remove the software, follow steps 4 through 6 b elow.

Chapter 6

6 Click Install or Remove.

If you are installing software, the selected items will be installed on your computer. If you are removi ng software, the selected items will be deleted from your computer.

The Installer may also remove or delete associated files that are required for the items you choose.

7 Repeat steps 4 through 6 for all the software you selected.

After you finish installing or removi ng a software product, the Installer for the next product you selected opens automatically.

8 After you’ve installed all the software you selected, restart your computer.

Problems during installation

This section helps you solve problems you may encounter while installing your software.

You can’t start up the computer using the system software CD-ROM disc.

Cause: Your computer located the system software on your hard disk before it located the system software on the CD. If you have an external hard drive with system software, the computer may have started up from that device instead of the CD-ROM disc.

Solution: With the CD in the drive, open the Startup Disk control panel and click the CD icon. Then restart the computer.

You’ll n eed to reselect your hard disk as the star tup disk after you i nstall the software. Open the Startup Disk control panel agai n and click the icon for your hard disk. Then restart your computer.

Diagnostic Techniques

The Installer cannot repair your hard disk.

Cause: The Mac OS Install program is unable to repair a problem with your hard disk.

Solution 1: If you see a message that the disk ca n’t be fixed because a file is open or file sharing is on, make sure that you have started up your computer from the system software CD. See “Using a CD to Start Up Your Computer” earlier in this chapter.

Solution 2: Use a third-party disk repair utility to repair the disk. If you don’t have a third-party utility, or if that utility can’t repai r the disk

either, you may n eed to reinitialize the hard disk. First, back up your hard disk because reinitializing erases everything on the

disk. Then use the Drive Setup utility program to reinitialize the disk. If your hard disk is not an Apple hard disk, use the disk utility software provided by the manufacturer instead of Drive Setup.

You can find Drive Setup in the Utilities folder on your system software CD-ROM disc. To reinitialize your startup disk (the disk with system software on it), you need to start up the computer from a different disk. You can start up using your system software CD-ROM disc. See “Using a CD to Start Up Your Computer” earlier in this chapter for instructions.

After you’ve reinitialized the disk, use the Mac OS 8 Install program to reinstall system software. Then reinstall your application programs.

You see a message that there’s not enough disk space.

Cause: Your computer’s hard disk has less than the minimum amount of space required to install the software.

Solution: Make more space available on your hard disk by removing some files from the disk. Make backup copies of the files, if desired. Then drag them to the Trash and choose Empty Trash from the Special menu. You don’t need to quit the Installer before you remove the files from the disk.

When you see this message, some of the software you selected may have been installed. The Install Software window in the Installer program indicates which software has already been installed.

Chapter 6

You see a message that the System file cannot be modified.

Cause 1: You have installed virus-protection software that guards against modification of the System file.

Solution 1: Start up your computer from your system software CD-ROM disc as described in “Using a CD to Start Up Your Computer” earlier in this chapter.

Solution 2: Drag any virus-protection sof tw are out of the S ystem Folder and restart your computer. You can put the virus-protecti on s oftware b ack after installat i on.

Caus e 2: The System and Finder files may be locked. Solution: Make sure that you have started up from the CD. Then, to see if

your System file or Finder file is locked, select the file’s icon. Then open the File menu and choose Get Info. To unlock the file, click the Locked checkbox to remove the mark.

Performing a clean installation

This section provides instructions for what is commonly called a clean installation of system software.

A normal system software installation replaces changed system files and adds new ones, but leaves other files alone. When you install system software using a clean installation, the Installer creates a new System Folder on your hard disk. The old System Folder is renamed Previous System Folder. Since your computer has a new System Folder, you must reinstall any third-party extensions and control panels after a clean installation. Application programs and documents are not replaced or changed.

Performing a clean installation ca n be a complicated proced ure, but if you are experiencing problems or your computer seems slow, it may help.

If your computer came with software that was already installed, some of those programs might n eed to be reinstalled after you perform a clean installation. See the printed or electr oni c manuals that cam e with the software for inf ormation.

Diagnostic Techniques

Follow these steps to perform your clean installation.

1 Start up your computer from your system software CD-ROM disc, as described in “Using

a CD to Start Up Your Computer” earlier in this chapter.

2 Open the Mac OS Install program. 3 In the Welcome dialog box, click continue.

The Select Destination dialog box app ears.

4 Click the Perform Clean Installation checkbox so that it has a mark in it. 5 Click Select. 6 Select the software products you want to install.

For more information about the choices available, or for instructions on further customizing your selections, see “Selecting Which Software to Install” earlier in this chapter.

7 Click Start to install the software you’ve selected.

A new System Folder is installed on your hard disk. (The old System Folder is renamed Previous System Folder.)
