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. Do not use liquid or aerosol cleaners, which may contain flammable substances.

NOTE: It is recommended that you use the wipedown cloth, included as part of the accessories, to wipe your system without scratching the glossy exterior.

•Use a can of compressed air to remove dust 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.

NOTICE: To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for cleaning displays, and follow the instructions that are included with the product.

•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

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

1Turn the retainer ring on the underside of your mouse counterclockwise, and then remove the ball.

2Wipe the ball with a clean, lint-free cloth.

3Blow carefully into the ball cage to dislodge dust and lint.

4If the rollers inside the ball cage are dirty, clean the rollers with a cotton swab moistened lightly with isopropyl alcohol.
