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 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 allow water to 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.

Floppy Drive

NOTICE:

Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads, which prevents the drive from operating.

Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppy disks to remove contaminants that accumulate during

normal operation.
