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.
