Cleaning Your Computer

CAUTION: Before you begin any of the procedures in this section, follow the

safety instructions 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 a 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 water.

Do not soak the cloth or let water drip inside your computer or keyboard.

Mouse (Non-Optical)

Turn the retainer ring on the underside of your mouse counterclockwise,

and then remove the ball.

Wipe the ball with a clean, lint-free cloth.

Blow carefully into the ball cage to dislodge dust and lint.

Clean the rollers inside the ball cage with a cotton swab moistened lightly

with isopropyl alcohol.

Recenter the rollers in their channels, as needed. Ensure that fluff from

the swab is not left on the rollers.

Replace the ball and retainer ring, and then turn the retainer ring clockwise

until it clicks into place.
