Before Cleaning Your Computer

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

safety instructions in the

System Information Guide

Shut down the computer through the

Start

menu.

Ensure that your computer and attached devices are turned off. If your computer and

attached devices did not automatically turn off when you shut down your computer,

turn them off now.

NOTICE:

To disconnect a network cable, first unplug the cable from your computer and then

unplug it from the network wall jack.

Disconnect any telephone or telecommunication lines from the computer.

Disconnect your computer and all attached devices from electrical outlets, and then

press the power button to ground the system board.

Computer, Keyboard, and Monitor

• Use a vacuum cleaner with a brush attachment to remove dust from the slots and

holes on your computer and between the keys on the keyboard.

NOTICE:

Do not wipe the monitor 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 liquid dishwashing

detergent. Wipe off stubborn stains with a cloth lightly moistened with isopropyl

alcohol.
Do not soak the cloth in the solution or let the solution drip inside your computer or

keyboard.

Mouse

If your screen cursor skips or moves abnormally, clean the mouse. To clean a non-optical
mouse:

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

remove the ball.
