Tips for Using Your Computer

The following information helps you avoid potential problems as you use your computer:

Do not try to disassembl e your computer. Opening the system chassis voids your warrant y. Only an authorized service center can replace or add any parts inside the chassis.

• Follow all the instructions and cautions in your computer user

documentation.

• The LCD has a polarized surface a nd can be damage d easily. To prevent

damage, avoid touching the screen.

• Use only approved AC adapters, and memory modules.

Using Your Computer for the First Time 9

• Because a portable computer is small and has restricted air flow around

components, it is more likely to overheat than a desktop computer . A fan

inside your comp uter he lps to el imina te some heat . Make sure the f an v ent on

the side of your computer is not blocked when you use the computer. (See

Figure 1 on page 3 for the location of the vent.) Occasionall y check the vent

and remove any accumulated dust on the outside .

• Avoid using or storing the computer in extrem ely hot or cold areas, such as a

car on a hot day. Keep the computer away from heaters and out of direct

sunlight. Exposure to excessive heat may damage computer components.

If you have left your computer in a hot place, let it cool down slowly to room

temperature (with the LCD panel open) before using it.

• Do not remove the memory-module compartment door, or try to install a

memory module when the computer is on. (See Figure 3 for the location of

the door.)

(For information on installing memory modules, see “Memory Modules” on

page 77.)

• Set up your computer work area to a void physical strain. Si t with your back

straight and supported by your chair. Adjust your chair or work table so that

your arms and wrists can remain in a relaxed positi on, parallel wit h the floor.

Avoid bending or twisting your wrists as you work. Your hands should

“float” slight ly above the ke yboard. Refer to a book on office ergo nomics for

more information on setting up your work area.

• Take frequent breaks from working at the computer to rest your eyes and

stretch your muscle s.

• Remember to save your data files frequently and to make back up copies of

your files.

Traveling with Your Computer

If you are traveling by airplane, follow these tips:

• Take the computer with you as carry-on luggage. Do not check th e computer

with your baggage.

• Allow the computer and disks to go through the

X-ray security devices. Do not hand-carry disks through the walk-through

metal detectors, which can cause loss of data.

Using Your Computer for the First Time 10

• Mak e s u re th at th e ba tt er y is ch a rg e d or the AC ad ap t er is ea sily accessibl e.

You may be required to turn on the computer for airport security personnel.

• Be prepared to turn off the computer during take off and landing.

• Contact your a irline for inf ormation a bout usi ng an opt ion al ai rli ne ada pter t o

power your computer while traveling by airplane.

Handling Spills

Do not spil l anyt hing on your com puter. T he best way to avoid s pills i s to a void eat ing and drinking aroun d your comput er. If yo u do spill somet hing on yo ur computer, t urn off your computer, unplug it immediately, and do the following:

• If you spill liquid on the keyboard, drain as much of the liquid from the

keyboard as p ossi ble. Be c ar eful not to let t he l iqu id d rip o nto the LCD pan el.

Allow the system to dry for several days before trying to use it.

• If you spill liquid on an external keyboard or keypad, unp lug it and drain as

much of the liquid a s pos sible. Al low t he keyboa rd to si t at roo m tempera ture

for a full day before trying to use it.

Sweet liquids leave a sticky residue that may jam the keyboard despite your efforts to dry it.

• If you spill liquid on the LCD pa nel, clean it immediately with a soft cloth

and denatured alcohol. Do not use water, window cleaner, acetone, aromatic

solvent, or dry, rough towels to clean it.

Some liquids damage the polarized LCD screen. If your screen is damaged, contact your authorized manufactur er’s service center for a replacement.

Storing the Computer for Long Periods

If possi ble, leav e the AC a dapte r co nnecte d to th e compu ter when t he comp uter i s not in use. This helps extend the life of the battery and keeps the battery fully charged.

Using Your Computer for the First Time 11

Using the Hard Drive

Your computer inc ludes a removab le IDE h ard drive . The IDE hard driv e can st ore t he data and prog rams your c ompute r use s. The drive pl ugs int o a connec tor on th e sys tem board.

Although th e stor age capa city o f har d drives varie s acco rdin g to mode l, a ny hard dri ve holds much more than a floppy disk does. Also, the computer reads and works with a hard drive more rapidly tha n with a floppy disk.

Once informatio n is s aved on a hard dri ve, it rema ins th ere unti l it i s overwri tt en. Hard drive heads park aut oma tically when you turn off your comput er.

The hard driv e that com es with y our compute r has a lready been formatted. Do not for m at the hard drive. Doing so destroys all data contained on the drive. If you need to format a new drive, or want to erase all data on your exist ing hard drive, refer to the manual for your operati ng system.

Although Windows 98 can work with FAT-16 or FAT-32 (a 32-bit file allocation table) , there are softwar e compatibility issues with FAT-32. Older software that you may have (16-bit software ) requires FAT-16 to run.

Removing the Hard Drive

To prevent loss of data and dam age to the disk, do not remove the hard drive while the comput er’s power is on and do not drop or jar the hard drive.

To remove the hard dr iv e from the computer:

1. If you are installing a new hard drive, backup the application and data files on

the old hard drive before removing it from the computer.

2. Turn the computer’s power off.

3. Close the LCD panel, and turn the computer ove r so that the bottom of the unit

Using the Battery

Your computer uses a smart rechargeable lithium-ion battery pack for power when the AC adap ter is not at ta ch ed to an electrica l ou t le t.

Charging the Battery

Your computer’s battery starts charging automatically when you connect the AC adapter to th e co mputer . If th e co mp u ter is off, th e batter y cha r g es f as t er th an if th e computer’s power is on.

Approximate charging times for your battery are

• 3 hours with the compute r off

• 6 hours with the compute r on

While the battery is charging, the battery charge light on the computer is amber (see Figure 9 on page 19 for the location of the battery charge li ght). When the battery is fully charged, the light changes to green.

You can also us e the opti onal exte rnal batt ery cra dle to cha rge the bat tery while it is not in the computer. (See “Battery Cradle” on page 82 for more inform at ion.)

When you use a new batt ery pack for the first tim e or use a battery after a long period of storage, the ini tial battery life is short er tha n normal. Normal battery life resum es after a few discharge-recharge cycles.

Follow these rules for cha r ging your battery:

• A battery normally discharges power when not used for long periods of time.

Be sure to recharge the ba ttery every two months when it is not in use.

• Make it a practice to discha rge your ba ttery ful ly before recharg ing t he batt ery.

This can help extend the life of the battery.

• Do not attempt to charge the battery in temperat ures of under

over 95

F (35oC

41o F (5o C) or

Using the Battery 34

All batteries eventually wear out and lose the ability to hold a charge. Y ou m ay need to re place your battery pack after a year of average usage.

Safely Using the AC Adapter and Batteries

Follow these gui delines to safely use the AC adapter a nd batteries:

• Turn your equipment off and unplug the AC adapter if you accidentally:

– Expose the equipmen t to liquid. – Drop, jar, or damage the comput er.

• Use only approved AC adapt ers and automobile and airline adapters.

• Do not disassemble the battery, heat it above 122° F (50° C), or burn it. The

batter y u sed in th is comput er ma y ca u s e a fir e o r che m i ca l b urn if mis t r ea te d .

• Your computer's rechargeable battery may be considered hazardous waste. If

you replace your battery with a new one:

– Keep the old battery out of the reach of children. – Dispose of the old batter y prom ptly. – Make sure that you follow all state and local requirements when you

dispose of the old ba ttery.

Removing and Installing the Battery

4. Align the tabs on the batte r y com partment cover with the s lots on the battery

compartment.

5. Push the cover straight down until it snaps into place.

Monitoring the Battery Charge

Battery life is affected by factors such as the power-management settings in System Setup, the applications you use, and the brightness and contrast settings of the LCD. Under normal usage, the battery charge lasts approximately 2 hours.

Using the Battery 36

Battery li fe estimates are subject to variat ion. The actual life of your battery may be less than the estimates given in the documentation.

You can monitor the charg e of the battery pack inst alle d in your comput er through th e battery gauge.

Using the Battery Gauge

You can display the ba ttery gauge while you are in any progra m. Pr es s <Fn+F6> to display the battery gauge on the LCD (Figure 18).

Figure 18. Battery Gauge

The gauge has two sections:

• The top section of the gauge shows a picture of a battery to indicate that the

computer is opera ting from the battery.

• The bottom section of the gauge shows you the amount of batte r y cha r ge

remaining.

While the batte ry ga uge is dis pl ayed, all ke ys are dis able d. The batte ry gauge clos es in a few seconds.

Because of the characteristics of battery cel ls, the battery gauge may be inaccurate for 10 m inutes after you charge the

battery. Wait unt il the computer has been operating from the battery for 10 minutes before you check the battery gauge.

Using the Main Battery Lights

There are four bat tery st atus lights on the main batt ery th at indic at e if the main bat tery is charging and the a mou nt of battery charge remaining.

To see how much charge remains in t h e main battery, remove the battery (See “Removing and Instal ling the Batt ery” on page 35 for more inf ormation.) and pres s the battery status button. Each light indicates a 25 percent charge. For example, if three lights ar e on, the battery h as a 75 percent c harge. T he batter y status l ights a utomatic ally turn off two seconds aft er you release the battery status button.

Using PowerProfiler to Monitor the Battery

PowerProfiler enables you to set power-management options for computers shipped with Windows NT installed. To use PowerProfiler to monitor the battery charge, place the cur sor on the battery icon in the right corner of the task bar. PowerProfiler shows you the amount of batte r y cha r ge remaining.

The color of the battery icon also indicates approximate battery charge:

• Green: Charge is adequate to power computer.

• Yellow: Char ge is low.

• Red: Charge is very low.

You can determine at what battery cha rge level P owerProfile r shows the low and very low colors. The default setting for the very low lev el is 20 percent battery charge remaining.

To set battery monitoring options in PowerProfiler:

1. Double-click the PowerProfiler battery icon to open the software.

2. Click the Battery tab.

3. Set options under Battery Status and Alarm Settings.

You can disa ble this option by selecting Off, or you can specify a Suspend Timeout delay time of from 5 to 60 minutes.

The Suspend Mode field in System Setup defines what type of suspend mode your computer enters:

• Power On Suspend: This mode saves power by turning off the micro processor

and DMA clocks, video, and all c ontrollable peripheral devices. T he computer still uses some power while in th is mode. If you leave your computer in power on suspend for several days without the AC adapter attached, the computer’s battery will discharge.

Using Power Management Options 58

• Save To Disk: Thi s mode provides the greatest power-saving capabilities by

essential ly turn ing off yo ur compu ter. In th is mode , all sys tem logi c ( except for your computer wake up circu itry and batte ry charge r) is t urned off. During s ave to disk mode, th e DRAM and video m emory are sav ed to t he h ard driv e and a re restored when your computer resumes operation.

You can press <Fn+F11> to manually place your computer into suspend mode.

When you use the <Fn+F11> key combination, your computer may postpone entering suspend mode during a critical operation, such as reading from or writing to the hard drive.

To resume to full-power mode, pres s the power button. Once all devices return to full-p ower mode, all act ive software appl ications and system

states are restore d to exactly how they were before your computer entered suspend mode.

When your computer enters or resumes from save to disk mode, screens appe ar indicating system status . These status s creens do no t appear when th e computer enters or resumes from power on suspend.

Suspend Mode Precautions

Observe the following precautions when using s uspend mode:

• Save all open file s before you press <Fn+F11> to manual ly place your

computer into suspend mode.

• If you purchased a new hard drive, make sure that you create a save to disk

partition equal to the amount of system memory plus 2 MB before you enable save to disk mode. See “Cre ating a Save t o Disk Pa rtiti on” on pa ge 62 for m ore information.

• Do not try to resume to full-power mode using battery power if the battery

charge is low. If the battery charge is too low, the system may not be able to resume fully. Plug in the AC adapt er if your computer cannot resume normal operation because of a low battery charge.

Using Power Management Options 59

When your computer is in power on suspend or save to disk mode, do not connect or remove any devices (including PC Cards or memory modules) because you may damage the computer or resume to full power may fail. If a floppy disk is in the floppy drive, do not remove it or switch it with another disk.

However, you can plug in the AC adapter if the resume to full power fails because of a low batte ry charge.

When the computer is in save to disk mode, you can remove and replace the batte ry.

Using PowerProfiler

PowerProfiler enables you to set power-management options for computers shipped with Windows NT instal led. To open the PowerProfiler window, double-click the battery icon on the right corner of the Windows taskbar. If you c lick the icon with the right mouse button, a menu appears with an option to put the computer in suspend (suspend mode).

Click the Stand ard tab in PowerProfil er to s et t imeouts for the LC D and th e hard d rive. You can also s et power mana gement to be enabled Always, Battery Only, or Never. The Advanced screen in PowerProfiler enables resume from suspend options, and the Battery screen enables options to conserve battery life.

Keep the following in mind when using PowerProfiler:

• If you disable power management in PowerProfiler, the setting overrides any

power-m anagement s ettings in System Setup.

• If you enable LCD and hard drive timeouts in PowerProfiler and the standby

timeout in S y stem Setup, the LCD and hard drive tu r n of f when the shortest timeout period in either program passes.

• If you disable the Resume on Time field in System Setup, the same field in

PowerProfiler is also automatically disabled. An easy way to work with these two fields is to set the resume time to 0 in System Setup and set the actual resume time that you desire in PowerProfiler.

• To enable your computer t o resume from sus pend on a modem ring, enable the

Resume on Modem field in System Setup and the same field in PowerProfiler.

Using Power Management Options 60

PowerProfiler maintains the accu racy of th e system c lock when the computer re sum es from suspend mode. If PowerPr ofiler is closed or remove d from your hard drive, yo ur system clock may not be accurate when your computer resumes from suspend mode.

For more information on PowerProfiler, see the Help option in the PowerProfiler software.

Changing the Video Configuration

Your computer includes a TFT screen or active-matrix. The capabilities of the screen plus the v ideo drive rs install ed on the computer determine t he quali ty of th e image your LCD can display.

The following sections describe the display capabilities of your computer.

Resolution and Color Depth

The resolution of the LCD is the sharpness of the im age it can display. Resolution is measured by the number of pixels (individual dots) displayed on the entire screen. In general, the more pixels the LCD can display, the be tter the image.

Your LCD screen is either SVGA or XGA:

• The maximum display for the SVGA LCD screen is

800x600, about 480,000 pixels.

• The maximum display for th e XGA LCD screen is 1024x768, about 800,000

pixels.

The number of c olors the LCD can dis play is meas ured by how man y bits th e LCD uses to repr esent each pi x el :

• 8-bit color can suppor t 256 different colors.

• 16-bit color can support 64 K (65,536) colors.

• 24-bit color can support 16 M (16.8 million) colors.

• 32-bit color can support 16 M (16.8 million) colors.

24-bit color uses the RGB color model. 32-bit color uses the CMYK color model which gives bette r pr inted color matching. Table 7 list s the basi c video mode capa bilit ie s and ma ximum col ors support ed by your

computer.

The basic unit of measure for computer memory. A character—such as a letter of the alphabet—uses one byte of memory. Computer memory is often measured in kilobytes (1,024 bytes) or megabytes (1,048,576 bytes).

Each byte is made up of eight bits. For more information on bytes and bits, see an introductory book on computers.

Cache memory

Cache is very fast, zero-wait-state memory located between the microprocessor and main memory. Cache reduces the average time required for the microprocessor to get the data it n eeds from the main memory by storing recently accessed data in th e cache.

CardBus

CardBus techn ology enabl es the comput er to use 3 2-bit PC Cards. H ardwar e in t he computer and the Windows 98 operating system provide support for the 32-bit cards. The voltage of 32-bit cards (3.3 volt s) is lower than that of 16-bit cards (5 volts). The 32-bit cards can transmi t more data at a time tha n the 16-bit ca rds, thu s increasing the ir s pee d.

CMOS memo ry

CMOS (complementa ry metal oxide semiconductor) mem ory is powered by the CMOS battery. T he Sy stem Set up se ttings and ot her p arameters are m ainta ined in CMOS memory. Even when you turn your comput er off, the informati on in CMOS memory is saved.

COM port

COM stands for communi cati on. COM ports are the serial por ts in your com puter.

Conventional memory

The first 640 KB of syst em memory. Opera tin g sys tems and appl icat ion program s can directly access this memory without using memory-management software.

CMYK

A a color model in which all colors are described as a mixture of four process colors - Cyan, Magent a, Yellow and Black. CMYK is the standard color model used in offset printing for full-color documents. Printed colors look the same as what appears on the screen.

Disc

A compact disc (CD).

Disk

The device used by the computer to store and retrieve information. Disk can refer to a floppy disk, hard dis k, or RAM disk.

Disk cache

A software device that accumulates co pies of recently u sed disk se ctors in RAM. The application program can then read these copies without accessing the disk. This, in turn, sp ee ds up the performance of the application.

A cache is a buffer for transfe rring disk sectors in and out of RAM. Data store d in a disk cache is a copy of data already stored on the physical disk.

Glossary 89

DMA (direct memory access)

A method of transferring data from a device to memory without having the data pass through the microprocessor. Using DMA can speed up system performance.

Floppy disk

A removable disk, also called floppy or diskette.

Hard drive

Also ca ll ed fi xed disk. A hard drive is connected to the com puter and can be installed or remove d. Data wri tten t o a ha rd dri ve remai ns unt il it is overwri tte n or corrupted.

The 2.5-inch hard drive in your computer was designed for use in a por table computer. Beca use hard drives in portable computers are smaller than thos e in desktop computers, their maximum storage capacity may be less than that of desktop hard drives. However, because of their smaller size , the drives handle shock and vibration better than larger drives, which is important for a portable computer.

I/O

Input/output. Refers to peripheral device s, su ch as printers, that are address ed through an I/O address.

I/O address

I/O stands for input/output. Peripheral devices, such as printers, are addressed through the I/O port address.

IRQ (interrupt request line)

The IRQ is a hardware line that a device uses to signal the microprocesso r when the device n eeds the micropr oce ssor ’s servic es. The num ber of IRQs is lim ited by industry standards.

LCD (liquid-crystal display)

The LCD screen on your computer differs from the display screen of a desktop monitor. Most desktop monitor s use CRT (cathode-ray tube) displa ys, which work by moving an electron beam across phosphor dots on the back of the screen. The phosphor dots light up to show the image. LCDs use a liquid-crystal solution between two sheet s of pol arizing material. Electric current passing through the liquid alig ns the crys tal s so t hat li ght can or c annot pa ss t hroug h them , crea ting an image.

1,024 kilobytes.

Megabit

1,048,576 bits or about 128 kilobytes.

Operating system

A program that supervises the computer's operation, including handling I/O. Application programs and users can request ope rating-system services. A user might request operation-system services to copy files or format a disk. An applicati on program might use the operati ng sy stem to obtain keyboard input, write data to a file, or write data to a screen.

PC Card

PC Card stands for personal comput er card. The Pe rsonal Computer Memory C ard Internationa l Ass ocia tion (P CMCIA) defi nes th e standa rds us ed to de velop a ll PC Cards. PC Card types include: modems, Ethernet adap ters, SCSI adapters, ATA cards, and memory cards.

PC slot

The PC slot is the hardware slot in the computer where the PC Card is placed.

Pixel

A pixel is an individual dot in a graphic displayed on your computer. The pixels are so close together that they look as though they are connected. An LCD screen displays thousands or millions of pixels.

Plug and Play

A plug and pla y op erati ng sys tem aut omat icall y confi gure s comput er com ponent s to work with your syst em. With thi s type of oper ating system , you normally do not need to set jumpers on devices or set memory addresses or IRQs.

POST

POST stands for power-on self-test. POST is a test performed by the computer whenever you turn on the power. POST checks system integrity.

RAM (random access memor y)

The computer's system memory, including conventiona l and extended memory. You can write to and read from RAM. Information stored in RAM is temporary, and is erased when the system is turned off.
