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)

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

5 Recenter the rollers in their channels, as needed. Ensure that fluff from the swab is not left on the rollers.

6 Replace the ball and retainer ring, and then turn the retainer ring clockwise until it clicks into place.
