CAUTION
Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect the surface, e.g., discoloration. In addition, do
not use commercially-available household cleaners and cosmetics, as they may contain components harmful to the surface.
Do not directly add or spray water or detergent. If liquid enters the inside of the computer, it may cause it to work improp-
erly or be damaged.

Places not to use your computer
Such areas may result in damage to the computer.
Areas with electronic equipment
These areas may interfere with your display or cause your computer to produce strange sounds.
Areas with extremely high/low temperatures
Do not leave things near the computer that are sensitive to heat. During operation, the computer may
become warm.
Do not drop or hit your computer against solid objects.
Do not carry your computer when it is on.
Remove all external devices, cables, and PC Cards sticking out of the computer (see the
figure on the left) before transporting the computer.
We recommend preparing a fully charged battery.
When transporting a spare battery inside a package, briefcase, etc., it is recommended that it
be placed in a plastic bag so that its contacts are protected.
Do not carry the computer while the display is open, or carry it by gripping the display.
Do not put anything (e.g., a piece of paper) between the display and keyboard.
Always carry your computer with you. Never check it in with luggage. For use of the com-
puter inside an aircraft, we recommend asking the airlines regarding their policy on this issue.
It is a good idea to make backup copies on disks and carry them with you.
Do not leave a disk in the drive while transporting your computer.
Display
<Models with touchscreen>
Use the soft cloth included with the computer. (For more information, refer to "Suggestions
About Cleaning the LCD Surface" that comes with the soft cloth.)
<Models without touchscreen>
Avoid using water when cleaning the panel. Ingredients included in water may leave scratches
and reduce readability of the screen.
<When cleaning dust/dirt>
Avoid rubbing off dust/dirt with cloth since it may leave scratch on the screen.
Sweep dust/dirt with fine brush, then wipe it with a dry soft cloth used for cleaning glasses.
<When cleaning oily surface>
Apply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe with a
dry soft cloth used for cleaning glasses.
Areas excluding the display
Wipe these areas with a soft cloth, after applying water or detergent diluted with water to the
soft cloth and firmly wringing out excess water.
