CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions located in
the
Product Information Guide
.
Computer, Keyboard, and Monitor
CAUTION:
Before you clean your computer, disconnect the computer from the electrical outlet. Clean your
computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain
flammable substances.
Use a vacuum cleaner with a brush attachment to gently remove dust from the slots and holes on your computer and
from between the keys on the keyboard.
NOTICE:
Do not wipe the display screen with any soap or alcohol solution. Doing so may damage the antiglare
coating.
To clean your monitor screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning
tissue or solution suitable for the monitor's antistatic coating.
Wipe the keyboard, computer, and plastic part of the monitor with a soft cleaning cloth moistened with a solution of
three parts water and one part dish washing detergent.
Do not soak the cloth or let water drip inside your computer or keyboard.
Mouse
If your screen cursor skips or moves abnormally, clean the mouse. To clean a non-optical mouse:
1. Turn the retainer ring on the underside of your mouse counterclockwise, and then remove the ball.
2. Wipe the ball with a clean, lint-free cloth.
3. Blow carefully into the ball cage to dislodge dust and lint.
4. If the rollers inside the ball cage are dirty, clean the rollers with a cotton swab moistened lightly with isopropyl alcohol.
5. Re-center the rollers in their channels if they are misaligned. Ensure that lint from the swab is not left on the rollers.
6. Replace the ball and retainer ring, and turn the retainer ring clockwise until it clicks into place.
Floppy Drive
NOTICE:
Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads, which prevents
the drive from operating.
Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppy disks to remove
contaminants that accumulate during normal operation.
