Correcti ons to the

This Getting Started manual provides instructions for setting up your PowerBook 150, learning basic Macintosh software skills, and using the many special features of your computer. In addition to this manual, your computer came with a Macintosh Reference book that provides instructions for performing many tasks that are common to all Macintosh and PowerBook computers.

Please note the following corrections in the Macintosh Reference book. You may want to mark these corrections on the appropriate pages of that manual for future reference.

References to the Disk Tools disk appear on pages 10, 19, 20, and 21 of the Macintosh Reference.

The Apple HD SC Setup and Internal HD Format utilities

The Apple HD SC Setup utility program that comes with many Macintosh and PowerBook computers is not designed for use with the internal hard disk of the PowerBook 150. Instead, your Utilities disk includes a utility program called Internal HD Format, which was designed to work specifically with the hard disk in your PowerBook 150 computer.

If you ever need to initialize your internal hard disk, refer to “Disk Drives and Disks” in Chapter 9 of this Getting Started book for instr uctions on using the Internal HD Format utility. Please disregard the instructions in “Initializing a Hard Disk” on pages 10–11 of the Macintosh Reference book.

You cannot use the Internal HD Format program to test a hard disk. Therefore, please disregard the instructions in “Testing a Hard Disk” on page 21 of the Macintosh Reference book.

Using a RAM disk

The instructions for setting up and using a RAM disk on pages 71–72 of the Macintosh Reference book are slightly incorrect for the PowerBook 150. Please refer instead to the instructions on pages 85–87 of this Getting Started book.

Corrections to the

What to do next

New Macintosh users:

If you have never used a Macintosh computer before, turn to Chapter 2 now to learn how to use your PowerBook. After you have completed Chapters 2 and 3, come back to this chapter for instructions on backing up your computer’s hard disk, turning the PowerBook off, and putting the PowerBook to sleep.

New PowerBook users:

new to the PowerBook, continue with this chapter. Then skim the rest of this book for information about your new PowerBook.

safety information in Chapter 4 before beginning your own work.

Backing up your hard disk

This section describes how to protect the software on your computer’s hard disk.

Why ba ck up?

Your computer’s hard disk comes with valuable information stored on it, including the system software (which operates the computer) and some application programs. You should make a copy of the information on your hard disk for safekeeping, using the PowerBook 150 Backup program supplied on your hard disk. (The extra copy is called a backup, and the process of making the copy is called backing up.)

If you have used other Macintosh computers but are

Read the rest of this chapter for instructions

No matter what your level of experience, be sure to read the

You should also make a copy of your System Folder. Then if the System Folder on the hard disk becomes damaged, you can quickly restore it from your backup copy.

To restore information to your hard disk, use the PowerBook 150 Restore program that came with your computer. See “Restoring the Information on Your Hard Disk” later in this chapter.

Chapter 1

What you need

High-density disks

have two holes...

...and they have

this symbol.

Just as you need paper to make copies of important documents, you need floppy disks to copy the information on your hard disk. You can probably buy the floppy disks at the same place you bought your computer.

Floppy disks come in a variety of sizes and capacities. The ones you need for backing up your hard disk are called high-density 3.5-inch disks. You can recognize the disks by the way they look:

Even though these disks have a hard plastic casing, they are called “floppy disks” because the disk inside the casing is floppy.

Depending on exactly what was installed on your computer at the factory, the information on your hard disk will fill more than 20 high-density disks. Disks usually come in boxes of 10, so you should have three boxes of disks before starting to follow the backup instructions in this chapter.

If you don’t have enough disks, you can skip this section for the moment. But the sooner you make the backup copy, the better. Buy the disks as soon as possible, then return to this section and follow the instructions.

For more information on using floppy disks, see “Using Disks” in the Macintosh Reference book.

Setting Up Your PowerBook

Making the copy

To start the PowerBook 150 Backup program, follow these instructions:

1 Turn on your computer. 2 Open the PowerBook 150 Backup program by double-clicking its icon.

After a moment, the PowerBook 150 Backup program opens.

Chapter 1

3Make sure your disks are high-density floppy disks. Then click the Continue button.

A message appears, telling you how many floppy disks you will need to make your backup copy and about how long it will take.

The number of disks and the copying time will vary depending on the contents of your computer’s hard disk.

4Click the appropriate choice, as follows:

m First click the Copy System Folder button, then continue with the

instructions in this section.

m When you have finished copying the System Folder, click the Copy all

Files button and again follow the instructions in this section.

m If you start copying and find that you don’t have enough floppy disks for

your choice, click Quit. Skip the rest of this section for now, and continue with “Turning Your Computer Off” later in this chapter. Buy floppy disks as soon as you can, then follow the instructions in this section to back up all of your hard disk.

Make sure you have enough time and floppy disks to complete the copying. If you stop the copying before it’s finished, you’ll have to start over again from the beginning.

Setting Up Your PowerBook

5Insert a high-density floppy disk into the disk drive.

Insert metal end first, label side up.

Do not use the Utilities floppy disk that came with your computer.

6 Follow the instructions on the screen until a message tells you that you’re finished.

Insert a new disk whenever the screen messages tells you to. As you fill each disk, make a note of the name displayed on the screen. The name will disappear as soon as the disk is ejected. Then immediately label the disk so that you know what its contents are later.

7 Follow steps 3–6 again, but this time click the Copy all Files button. 8When you’re finished, be sure the floppy disks are properly labeled and locked, then

store them in a safe, cool place.

As time goes by, you will store more information on your computer. You should back up your hard disk at least once a month. (You may want to recycle your backup disks so that you don’t need to buy a new set every time you back up.)

Chapter 1

Restoring the information on your h a rd disk

If information on your hard disk is damaged or lost, you can restore it if you have a backup copy of the information. Your PowerBook comes with a program called PowerBook 150 Backup, which you can use to back up the information on your hard disk. Then if you need to, you can use the program called PowerBook 150 Restore, also included with your computer, to put the copied information back on your hard disk.

You can also use PowerBook 150 Backup to make a copy of your System Folder (the folder that contains the software the computer uses to operate). If your computer does not start up anymore, replacing the System Folder may solve the problem. You can use PowerBook 150 Restore to replace the damaged System Folder on your hard disk.

For instructions on using PowerBook 150 Backup, see “Backing Up Your Hard Disk” earlier in this chapter.

IMPORTANT

If at any time during restoring you see a message reporting that the hard disk is damaged or unreadable, see “Using Disks” in the Macintosh Reference book.

To use PowerBook 150 Restore to restore information to your hard disk, you need the Utilities floppy disk that came with your computer and the floppy disks that you used to back up your hard disk. Follow these steps:

1Make sure the computer is off. 2 Insert the 3If necessary, open the Utilities icon by double-clicking it. 4 Open the PowerBook 150 Restore program by double-clicking its icon.

Utilities

disk into the floppy disk drive, then turn on the computer.

Setting Up Your PowerBook

In a moment you’ll see this screen:

5Click the Continue button. 6Insert your first backup disk.

Restoring begins and proceeds automatically.

7 Respond to any messages you see on the screen.

If PowerBook 150 Restore finds an item on your hard disk that is newer than an item with the same name on the floppy disk, it asks whether you want the older version of the item to replace the newer version. Click your choice. If you think the item on the hard disk may be damaged, you should replace it.

8Insert the next disk in your stack of backup disks and repeat step 7.

Continue inserting disks until you have gone through all the disks in the stack. Make sure you insert disks in the correct order.

The PowerBook 150 Restore program lets you know when you are finished. Return your backup disks to a safe, cool place for storage.

9 Restart your computer, then check to be sure that everything is back on your hard disk.

If the computer still doesn’t start up or your hard disk still doesn’t work properly, see “Using Disks” in the Macintosh Reference book. If you are able to repair the disk, then try again to restore the information on your hard disk.

Chapter 1

Restoring your System Folder

If your computer doesn’t start up anymore, replacing the System Folder may solve the problem. If you used PowerBook 150 Backup to make a backup copy of your System Folder, you can use PowerBook 150 Restore to replace the damaged System Folder on your hard disk with the copy on your backup disks.

To restore the System Folder to the hard disk, follow the instructions in this section, using the floppy disks that contain a backup copy of your System Folder.

Turning your computer off

When the PowerBook is off, the computer is not using any power or doing any work. You should always turn the computer off before attaching other equipment to it or replacing its battery. Also turn it off to conserve power when you won’t be using it for several hours.

To tu r n the computer off:

If the computer is on, choose Shut Down from the Special menu.

If the computer is in sleep, wake it by pressing any key on the keyboard (except Caps Lock), and then choose Shut Down from the Special menu.

Setting Up Your PowerBook

Putting your computer to sleep

When the PowerBook is in sleep, it has a darkened screen and appears to be off, though it is still drawing battery power at a low level. The computer is on, but almost completely inactive.

To put your PowerBook to sleep:

Choose Sleep from the Special menu.

Automatic s leep

If you don’t use the computer for several minutes, it goes to sleep automatically. This conserves battery power.

To wake th e computer, press any key on the keyboard (except Caps Lock). In a few seconds, the screen will go back to the way it looked before the computer went to sleep.

For more information on sleep and automatic sleep, see Chapter 6.

Chapter 1

Restarting your computer when it’s already on

You need to restart your computer—turn it off and back on again immediately—when you want to make certain changes to your control panels, use a newly installed system software file, or start up the computer from a different disk.

To restart your computer:

Choose Restart from the Special menu.

When you choose Restart, the computer prompts you to save your work, closes all open programs, and restarts itself.

Choosing Restart does not affect any RAM disk you created or its contents.

If you can’t choose Restart

You may occasionally see a “system error” message on the screen (indicating a temporary software problem). If this happens, you need to restart the computer. In most cases, the error message is accompanied by a Restart button. Use the trackball to click the Restart button.

For additional suggestions if you can’t restart using either of these methods, see Chapter 9, “Troubleshooting.”

Learning to Use Your Computer

Throwing an item away

As you work, you will want to remove items you no longer need from the hard disk. You remove items by throwing them into the Trash. In this exercise, you will throw the Practice File into the Trash.

1If the Macintosh HD window is not already open, open it by double-clicking the

Macintosh HD icon.

2If the folder named “My Work” is not already open, open it.

Note: If you can’t see the Trash icon (which should be in the lower-right corner of your screen), move the windows so that the Trash icon is visible. To move a window, place the pointer in the window’s title bar (the stripes at the top of the window), and drag the window.

3 Drag the Practice File to the Trash icon.

Place the pointer on the Practice File icon. Press and hold down the button as you move the pointer to the Trash icon.

When the tip of the pointer is on the Trash icon and the Trash icon becomes highlighted, release the button.

When you place an icon in the Trash, it is not immediately removed from your disk. The Trash icon bulges to show you that the Practice File is in the Trash, but still on your disk.

Chapter 2

4 Open the Trash icon (by double-clicking it) to see your Practice File there.

Your Practice File

is in the Trash.

5 Open the Special menu and choose Empty Trash.

6Click OK.

A dialog box appears. The computer displays a dialog box when it asks you to confirm an action. You must click OK or another button in the dialog box before you can take any other action.

The Trash is emptied and the Trash icon returns to normal. The Empty Trash command perman ently removes from your disk anything

that is in the Trash. Always be sure that you know what you’re removing before you choose Empty Trash.

Note: You can get an item back from the Trash by moving its icon back to your disk before you choose Empty Trash from the Special menu. After you choose Empty Trash, you can’t recover items you’ve thrown away.

You have completed all of the practice exercises. Before you continue with your own work, you might want to skim Chapter 3, “Basic Skills,” for a summary of basic skills that you’ll need as you work.

Learning to Use Your Computer

What’ s next?

The best way to get experience working with your computer is to begin to do your own work. You may have already purchased application programs to work with. Be sure to read the manuals that came with these programs for information on how to install them. You also have programs that came already installed on your computer. See the manuals that came with your computer for help on using these programs.

Clues on your screen

As you work, check the screen frequently for these important clues about where you are. If you are lost or if something unexpected happens, ask yourself these questions:

Is this the right p r ogram?

Check the menu bar. If it looks like this example, you are in the Finder. If any of these menu names are different or missing, you are inside another program. To get ba ck to the Finder, click anywhere on the desktop pattern.

The Finder menu bar

Chapter 2

Is the correct window active?

Usually only the active window is affected when you type or use a menu. The active window has stripes in its title bar. To make a window active, click anywhere inside it.

Is the icon or text you want to work with selected?

Commands you choose in menus often work only if an icon or some text is selected. Check the item you want to work with to make sure it’s highlighted (which means it’s selected).

Is it best to start over?

If you get stuck or lost as you practice on the computer, try one or more of the following remedies and then start the practice session over again:

m If an unwanted or confusing window is on your screen, click the Close box

in the upper-left corner of the window to close it.

m If an unwanted window or box contains a Cancel button, click it. m If the File menu contains the word Quit, choose it. m If you’re really stuck, restart your computer.

To restart, click the desktop (the background pattern on your screen), and then choose Restart from the Special menu. This turns the computer off and then back on. When you restart a computer, problems often clear up.

Health, Safety, and Maintenance Tips

Health-related information about computer u se

Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with using computers can occur from performing any number of activities. In fact, misuse of the same muscles during multiple activities can create a problem that might not otherwise exist. For example, if you engage in nonwork activities that involve repetitive stress on the wrist—such as bicycling—and also use your computer’s keyboard improperly, you may increase your likelihood of developing wrist problems. Some individuals are at greater risk of developing these problems because of their health, physiology, lifestyle, and general exposure to stress. Work organization and conditions, such as workstation setup and lighting, also play a part in your overall health and comfort. Preventing health problems is a multifaceted task that requires careful attention to the way you use your body every hour of every day.

The most common health effects associated with using a computer are musculoskeletal discomfort and eye fatigue. We’ll discuss each area of concern below.

Musculoskeletal discomfor t

As with any activity that involves sitting for long periods of time, using a computer can make your muscles sore and stiff. To minimize these effects, set up your work environment carefully, using the guidelines that follow, and take frequent breaks to rest tired muscles. To make working with your computer more comfortable, allow enough space in your work area so that you can change position frequently and maintain a relaxed posture.

Another type of musculoskeletal concern is repetitive stress injuries (RSIs), also known as cumulative trauma disorders (CTDs). These problems can occur when a certai n muscle or tendon is repeatedly overused and forced into an unnatural position. The exact causes of RSIs are not totally understood, but in addition to awkward posture, such factors as the amount of repetition, the force used in the activity, the individual’s physiology, workplace stress level, and lifestyle may affect the likelihood of experiencing an RSI.

Chapter 4

RSIs did not suddenly arise when computers were invented; tennis elbow and writer’s cramp, for example, are two RSIs that have been with us for a long time. Although less common than other RSIs, one serious RSI discussed more often today is a wrist problem called carpal tunnel syndrome, which may be aggravated by improper use of computer keyboards. This nerve disorder results from excessive pressure on the median nerve as it passes through the wrist to the hand.

This section offers advice on setting up your work area to enhance your comfort while you use your computer. Since the effects of repetitive movements associated with using a computer can be compounded by those of other work and leisure activities to produce or aggravate physical problems, proper use of your computer system must be considered as just one element of a healthy lifestyle.

No one, of course, can guarantee that you won’t have problems even when you follow t he most expert advice on using computer equipment. You should always check with a qualified health specialist if muscle, joint, or eye problems occur.

Eye fa ti g ue

Eye fatigue can occur whenever the eyes are focused on a nearby object for a long time. This problem occurs because the eye muscles must work harder to view an object that’s closer than about 20 feet (6 meters). Improper lighting can hasten the development of eye fatigue. Although eye fatigue is annoying, there’s no evidence that it leads to perman ent damage.

Whenever you’re engaged in an activity that involves close-up work—such as reading a magazine, doing craft work, or using a computer—be sure to have sufficient glare-free lighting and give your eyes frequent rest breaks by looking up and focusing on distant objects. Remember to have your eyes examined regularly.

To prevent discomfort and eye fatigue: m Arrange your work space so that the furniture is properly adjusted for you

and doesn’t contribute to an awkward working posture.

m Take frequent short breaks to give your muscles and eyes a chance to rest.

Health, Safety, and Maintenance Tips

Arran ging your work area and equipment

Not thisThis

The suggestions in this section can help you work more comfortably with your computer.

Chair

m An adjustable chair that provides firm, comfortable support is best. Adjust

the height of the chair so your thighs are horizontal and your feet flat on the floor.

The back of the chair should support your lower back (lumbar region). Foll ow the m anufacturer’s instructions for adjusting the backrest to fit your body properly.

Keyboard and trackball

m When you use the keyboard and trackball, your shoulders should be

relaxed. Your upp er arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

m You may have to raise your chair so your forearms and hands are at the

proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you may lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that’s lower than the regular work surface.

Chapter 4

m Use a light touch when typing or using the trackball and keep your hands

This Not this

and fingers relaxed. When using the trackball or keyboard, avoid rolling your thumbs under your palms.

Some computer users may develop discomfort in their hands, wrists, or arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.

m Change hand positions often to avoid fatigue. m If you prefer, you can adjust the angle of the keyboard by lowering the legs

until they snap into position.

The back of the keyboard is slightly elevated when the legs are in use. Otherwise, the keyboard is level.

Health, Safety, and Maintenance Tips

Built-in display

m Adjust the angle of the display to minimize glare and reflections from

overhead lights and windows.

m If your display screen has manual brightness and contrast controls, you

may need to adjust the brightness and contrast of the screen when you take the computer from one work location to another, or if the lighting in your work area changes.

Av oiding fatigue

m Change your seated position, stand up, or stretch whenever you start to feel

tired. Frequent short breaks are helpful in reducing fatigue.

m Allow adequate workspace so that you can work comfortably. Place papers

or other items so you can view them easily while using your computer. A document stand may make reading papers more comfortable.

m Eye muscles must work harder to focus on nearby objects. Occasionally

focus your eyes on a distant object, and blink often while you work.

m Clean your screen regularly. Keeping the screen clean helps reduce

unwanted reflections.

What about electromagnetic emissions?

There has been recent public discussion of the possible health effects of prolonged exposure to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic fields. Such fields are associated with electromagnetic sources such as television sets, electrical wiring, and some household appliances—as well as computer monitors.

Apple has reviewed scientific reports and sought the counsel of government regulatory agencies and respected health organizations. Based on the prevailing evidence and opinions, Apple believes that the electric and magnetic fields produced by computer monitors do not pose a health risk.

In response to those customers who wish to reduce their exposure to electromagnetic fields, Apple has lowered the emission levels of our products. We are also actively encouraging further scientific research so we can continue to promote the health and safety of our customers and employees.

Chapter 5

Read this chapter to learn

how you can maximize your

PowerBook battery life.

Power Management

Power sources

Your computer can draw its operating power from two different sources:

Main battery

battery. Depending on the battery conservation features you choose, the battery provides power for about 3 hours of work time.

AC power

plugging in the power adapter.

Your computer also has a backup battery that maintains the contents of RAM while you replace the main battery. The backup battery does not provide enough power to run the computer.

These power sources are described in more detail in the following sections.

Your computer’s main power source is a nickel-cadmium

You can run your computer from any standard electrical outlet by

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, do one of the following:

Plug in the power adapter.

Save your work and replace the depleted battery with a charged one.

Save your work, then shut down the computer until you can plug in the power adapter.

What you should know

The first low-power message is a reminder that the battery will soon run out. If you continue to work without plugging in the power adapter or changing

the battery, the computer displays a second low-power message. The second message is followed by a third and final 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 fir st two low-power messages 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 fully charged battery.

Chapter 6

If you can’t plug in the power adapter, the contents of RAM are retained in sleep for about a day. If you recharge or change the battery within a day, you should be able to wake the computer and resume work where you left off.

IMPORTANT

Recharge a depleted battery as soon as possible. Leaving a depleted battery in the computer for more than several months, or in a hot location (such as the trunk of a car) for longer than two weeks, may damage the ba ttery so that it can’t be recharged. If this happens, you need to replace the ba ttery.

Recharging the batte ry

Power adapter port

There are two ways to recharge a battery: m Plug in the power adapter to recharge the battery without removing the

battery from the computer.

m Remove the battery and recharge it in the (optional) recharger. Recharge a battery shortly before you plan to use it. The battery does not

retain its charge in long-term storage.

Rech arging in the computer

Plug i n the power adapter, as shown.

WARNING

Use only the power adapter that came with your computer (or a power adapter designed for use with other 100 series PowerBooks). Adapters for other electronic devices (including other portable computers) may look similar, but they may damage your computer.

Power Management

You can continue to use the computer while the battery is recharging, but the battery will take longer to recharge if you do. With the computer in use, recharging time depends on how often you use the hard disk, how bright the screen is, whether you are using an external monitor, how deeply the battery is depleted, and other factors.

If you recharge a fully depleted battery with the computer shut down, it takes about 2 to 3 hours to bring the battery to 80 percent of its capacity. It takes several more hours to bring the battery charge to 100 percent.

While the computer is shut down and the power adapter is plugged in, you can remove a charged battery from the computer and replace it with a battery you want to charge. If you do this, disconnect and then reconnect the power adapter after inserting the second battery; otherwise the second battery will not recharge.

Rech arging in a recharger

A battery recharger and additional batteries are available for purchase. If you purchase a recharger and an extra battery, you can charge one battery while you use the other, so you always have a fully charged battery on hand.

The recharger can accommodate two batteries; it charges them one battery at a time. You can put batteries in or take them out at different times.

Chapter 6

The recharger must be plugged into an electrical outlet to charge a battery. You can plug it in using the power adapter that came with your computer, or you can purchase an additional (identical) power adapter from your Appleauthorized dealer.

WARNING

Use only the power adapter that came with your computer with the recharger (or a power adapter designed for use with other 100 series PowerBooks). Using other types of power adapters may damage the recharger, the power adapter, or both.

To recharge a battery, follow these steps:

1Place the recharger on a level surface. 2Connect the recharger and the power adapter.

3Place the battery in the recharger as shown.

Recharging begins immediately. You can remove a battery from the recharger at any time.

IMPORTANT

To preserve a battery’s charge, don’t leave it in the recharger if the

power adapter is not plugged into an electrical outlet. The lights on the recharger indicate the following:

No light

Either the recharger is not plugged in, the other battery is being charged (if you have two batteries in the recharger), or the battery is defective. If the light goes off during recharging, there is a problem with the ba ttery.

Power Management

The table shows approximate recharging times for fully depleted batteries.

In the recharger:

1 battery 2.5 hours 5 hours 2 batteries 5 hours 10 hours

In the computer (shut down): 2–3 hours 6–8 hours

Removing or re pl acing the battery

You can remove or replace a battery only while the computer is asleep or shut down. To remove or replace the battery, follow these steps:

1Save your work, and then choose Sleep or Shut Down from the Special menu.

80% charge 100% charge

WARNING

If you choose Sleep, and the power adapter is not plugged in, the backup battery will protect open programs and documents for only about 4 minutes after you remove the battery.

2Close the display.

Doing so will prevent you from inadvertently pressing any keys and waking the co mputer.

3 Open the battery door by sliding the door in the direction indicated by the arrow.

The door is physically attached to the battery.

Chapter 6

4 Carefully pull the battery out of its compartment. 5If you are inserting another battery, slide it into the battery compartment.

Replacement batteries come with a door attached.

6Close the battery door by pushing it back into place. 7If 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.

Disposing of dead batteries

If you have a battery that can no longer be recharged, you will need to buy a new battery and dispose of the dead battery properly.

IMPORTANT

Nickel-cadmium batteries contain metals that are hazardous when released to the environment. It is inappropriate, and in some cases unlawful, to throw batteries away with your household or business trash. There are other ways to dispose of them.

In the United States: Return dead batteries to your Apple-authorized service provider, who will make sure they are included in Apple’s battery recycling program.

Elsewher e: Many countries have government- or Apple-sponsored collection and/or recycling programs for dead batteries. Dispose of dead batteries in accordance with the mandatory or voluntary battery collection schemes in your country. Contact your Apple-authorized service provider for information about the recommended battery disposal procedures in your location. If there is no government- or Apple-sponsored return program, you can dispose of the batteries with your regular trash, but take care not to break them open or incinerate them.

WARNING

Damaged nickel-cadmium batteries may leak small amounts of potassium hydroxide. This substance can cause severe burns to the skin a nd eyes. If you touch a damaged battery, immediately wash your hands and any other affected areas with water for at least 5 minutes.

Do not use soap.

Power Management

Replacing t he backup battery

In addition to its main battery, your computer has a small backup battery that maintains the contents of RAM while you replace the main battery.

The backup battery usually lasts for several years. You may need to have it replaced if you notice that some of your system settings changed after you removed or replaced the main battery. (You may notice, for example, that the clock time is different.) By replacing the backup battery you ensure that the contents of RAM will be preserved the next time you change the main battery.

Your computer’s backup battery must be replaced by an Apple-authorized service provider.

Reconditioning the battery

To maximize battery life, you should recondition the battery once every 30 days. Reconditioning means letting the battery run all the way down before you recharge it. By regularly reconditioning your battery, you help it maintain its maximum charge. Follow these steps:

1 Use the computer as you normally would, but ignore the low-power messages that

appear on the screen.

Make sure to save your work when you see the low-power messages.

2Allow the computer to go to sleep automatically after the third low-power message. 3 Recharge the battery completely before using it again.

See “Recharging the Battery” earlier in this chapter for instructions.

Chapter 6

Maximizing work time

Your PowerBook’s battery can provide several hours of work time before you need to recharge. The actual work time available depends on the equipment and power-saving features you’re using.

Ways to conserv e bat tery power

To conserve battery power, follow these tips:

m If you’re working near an electrical outlet, plug in the power adapter. m If you aren’t using the computer, either turn it off or put it to sleep and plug

in the power adapter.

m Tur n down the screen brightness (¤) whenever possible. At its brightest

level, the screen consumes about a third of the power your computer is using.

m Keep virtual memory turned off in the Memory control panel. m If your computer has 8 MB of memory or more, you can use a RAM disk

as your startup disk to minimize hard disk use.

m Quit any modem-related program as soon as you are finished using it. As

long as the program is open, your modem is consuming power even if you are not using the modem.

m Keep screen dimming on in the PowerBook control panel. The lower

settings dim your screen automatically if you haven’t used the computer for a few minutes.

m Tur n off AppleTalk i n the AppleTalk Switch module of the Control Strip or

in the Chooser.

m Set the Battery Conservation slider in the PowerBook control panel at

Better Conservation. The rest of this section describes these settings in detail.

Adjusting the b a ttery conservation settings

The Battery Conservation section of the PowerBook control panel gives you several ways to control your computer’s power consumption.

Power Management

The easiest approach

1Choose Control Panels from the Apple (

(Or use the Power Settings module in the Control Strip to open the PowerBook control panel.)

) menu and open the PowerBook control panel.

The PowerBook control panel opens in Easy View. You can also choose Custom View for more detailed options. See “Choosing Custom Options” later in this chapter.

2 Drag the Battery Conservation slider to the setting you want.

Battery Conservation slider

Better Performance allows you to work with the fewest interruptions (that is, the com puter going to sleep, the hard disk spinning down, or the screen dimming). If you can’t plug in the computer, Better Conservation gives you more work time.

3Close the PowerBook control panel.

If you don’t use the computer for several minutes, it goes to sleep without any action on your part. How many minutes pass before the computer goes to sleep depends on the battery conservation setting you chose.

To put the computer to sleep before automatic sleep takes effect, choose Sleep from the Special menu or use the Sleep Now module in the Control Strip.

To wake th e computer from sleep, press any key (except Caps Lock). Automatic sleep do es not take effect under the following circumstances:

m AppleTalk is turned on in the Chooser and the power adapter is plugged in. m Your computer is connected to a shared disk on the network. m Your computer’s printer port is in use. m Your computer’s internal modem is in use.

Chapter 6

More about automatic sleep

The Battery Conservation slider controls three power conservation features: system sleep, screen dimming, and hard disk spin down.

m System sleep is a state in which your computer uses only the power it needs

to maintain the contents of RAM (such as any open programs and documents, and various control panel settings).

m Screen dimming saves battery power by automatically turning off the

backlight of your PowerBook display screen.

m Hard disk spin down stops your computer’s internal hard disk from spinning

when it isn’t being used. If the PowerBook is in sleep, the hard disk automatically spins down.

The Battery Conservation slider has five settings:

The five settings on the Battery Conservation slider indicate the time it takes for your computer to go to sleep, the screen to dim, and the hard disk to spin down.

The time it takes for each feature to take effect depends on the setting you choose. If you drag the slider toward Better Conservation, it takes less time for the system to sleep, the hard disk to spin down, and the screen to dim.

The table indicates how much time passes at each setting before each power saving feature takes effect.

Processor cycling

If the computer is not doing anything for a few seconds, it turns off its microprocessor. The microprocessor comes back on the instant you resume work. This feature is called processor cycling. Processor cycling conserves battery power. Your computer automatically comes with processor cycling turned on, a nd it is highly recommended that you work with processor cycling on.

In a few cases, processor cycling can cause programs to slow down. If a program performs very slowly, you can turn off processor cycling temporarily. Foll ow these steps:

1Choose Control Panels from the Apple (

(Or use the Power Settings module in the Control Strip to open the PowerBook control panel.)

2Slide the switch to Custom.

) menu and open the PowerBook control panel.

Power Management

3Click the checkbox labeled “Allow processor cycling” to remove the X.

4Close the PowerBook control panel.

To turn processor cycling back on, click the “Allow processor cycling” checkbox agai n.

IMPORTANT

To conserve battery power, turn processor cycling off only when you are using programs that it interferes with. Turn pro cessor cycling back on again as soon as possible.

Processor speed

You can gain work time by slowing the computer’s microprocessor speed (from 33 to 16 MHz). Although some programs may work more slowly, you can gain up to 10 to 15 minutes of work time before you need to recharge the battery. (The amount of time you gain depends on how you are using the computer.)

To slow th e processor speed, follow these steps:

1Choose Control Panels from the Apple (

panel. (Or use the Power Settings module in the Control Strip to open the PowerBook control panel.)

2Slide the switch to Custom. 3Click the checkbox labeled “Reduced processor speed” to select it.

Chapter 7

Setting up a RAM disk

Usi ng a RAM disk saves power because it avoids using the PowerBook’s hard

disk while you are running the PowerBook from its battery. Any files that are

copied to the RAM disk are saved in the System Folder on the hard disk when

you shut down your PowerBook. The next time you start up your PowerBook,

the files are copied back to the RAM disk automatically.

A RAM disk lets you keep frequently used application programs and files in

RAM. For maximum battery conservation, you can also use the RAM disk as

your startup disk.

To set up a RAM disk, you need 8 MB or more of RAM in your computer.

Follow these steps. (If you don’t plan to use the RAM disk as your startup

disk, skip steps 1 and 2.)

1Select the System Folder on your hard disk and choose Duplicate from the File menu.

This creates a folder called “System Folder copy.”

2 Remove any extra extensions, fonts, and control panels you don’t use.

Do not delete the files called Finder, System, and System Enabler from the

System Folder copy or the file called Assistant Toolbox from the Extensions

folder in the System Folder copy.

3 Create a folder called RAM Disk Backup. 4Put the System Folder copy (if you’ll be using the RAM disk as your startup disk), your

favorite application program or programs, and files you frequently use into the RAM Disk

Backup folder.

Keep additions to this folder to a minimum.

Customizing And Traveling With Your PowerBook

5Select the RAM Disk Backup folder. Then choose Get Info from the File menu in the

Finder to determine the size of your RAM Disk Backup folder.

Yo u’ll need to remember the size of your RAM Disk Backup folder to set up a large enough RAM disk. Write it down if you need to.

6Choose Control Panels from the Apple (
