Appendix 115
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 dishwashing 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
Recenter the rollers in their channels if they are misaligned. Ensure that fluff 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.
