Cleaning Your Computer

Computer, Keyboard, and Display

CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet

and remove any installed batteries. Clean your computer with a soft cloth dampened with water.

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

• Use a can of compressed air to remove dust from between the keys on the keyboard.

NOTE: To avoid damaging the computer or display, do not spray cleaning solution directly onto

the display. Only use products designed for cleaning displays, and follow the instructions that

are included with the product.

• Moisten a soft, lint-free cloth with either water or a display cleaner, and wipe the display till it is clean.

NOTE: To prevent damage to the anti-glare coating, do not wipe the display with soap or

alcohol.

• Moisten a soft, lint-free cloth with water and wipe the computer and keyboard. Do not allow water

from the cloth to seep between the touchpad and the surrounding palmrest.

• To clean your monitor screen or display, lightly dampen a soft, clean cloth with water. You can also

use a special screen-cleaning tissue or solution suitable for the monitor’s anti-static coating.

• Wipe the keyboard, computer, and monitor plastics with a soft cleaning cloth moistened with a

solution of three parts water and one part dish-washing detergent.

CAUTION: Do not soak the cloth or let water drip inside your computer or keyboard.
