Cleaning Your Computer

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 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.
