Tips for Using Yo ur Computer

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

Do not try to disassemble your computer. Opening the system chassis voids your warranty. Only an authorized manufacturer’s service center can replace or add any parts inside the chassis.

• Follow all the instructions and cautions in your computer user d ocum entation.

• The LCD has a polarized surface and can be damaged easily. To prevent

damage, avoid touching the screen.

• Use only memory modules.

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

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

inside your co mputer runs when needed to help e liminate some heat. Make

sure the fan vent on the right side of your comput er and the air vent on the left

side are not blocked when you use the computer. (See Fi gure 1 and Figure 2

for the location of the vents.) Occasion ally check the vents and remove any

accumula ted dust on the outside.

• Avoid using or storing the computer in extremely 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.

10 User’s Manual

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 compartme nt door, or try to install a

memory module when the comput er is on. (Se e Fi gure 3 for t he loca tion of t he

door.)

(For information on installing memory mod ules, see “Memory Modules”.)

• Set up your computer work area to avoid physical strain. Sit with you r back

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

your arms and wrist s can remain in a relaxed position, parallel with the flo or.

Avoid bending or twis ting y our wri sts as you work. Yo ur ha nds shoul d “fl oat”

slightly above the keyboard. Refer to a book on office ergonomics for more

information on setting up your work area.

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

stretch your muscles.

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

your files.

Traveling with Your Computer

If you are traveling by airplane, follow these ti ps:

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

with your baggage .

• Allow the computer and disks to go through the

X-ray security dev ice s. Do not hand-carry disks through the wal k-through

metal detec tors , which can cause loss of data.

• M ak e sure that th e b at tery is char ge d or th e po w e r cord is easily accessible.

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.

Handling Sp ills

Do not spill anythi ng on your computer. The best way to avoid spi lls is to avoid eating and drinki ng around your computer. If you do spill something on your computer, turn off your computer, unplug it immediately, and do the following:

Usin g Your Co mputer for the F irst Time 11

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

keyboard as pos sible. Be careful not to let the liquid drip onto the LCD panel.

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

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

much of the liquid as possible. Allow the keyboard to sit at room temperature

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 pane l, cle an it i mmediat ely with a so ft clot h and

denatured al cohol. 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 manufacturer’s service center for a replacement.

Storing the Computer for Long Periods

If possi ble, l eave the pow er co rd conn ected t o th e comput er an d an el ectri cal ou tlet when the computer is not in use. Thi s helps extend the life of the battery and keeps the batt er y fully charged.

12 User’s Manual

If you will not be using the computer for a long period of time (a month or more), you should charge the bat tery until it is comple tely full. After you have done so, remove the batt er y from the unit.

Using the Keyboard

Your computer has an 87/88-key keyboa rd (Figure 7). By pressing designated key combinations, you can have access to a ll the key functi ons of a full-s ized keyboa rd.
