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.
 
NOTICE: 
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.
