A Routine care

Cleaning the display

CAUTION: To prevent permanent damage to the computer, never spray water, cleaning fluids, or chemicals on the display.

To remove smudges and lint, frequently clean the display with a soft, damp, lint-free cloth. If the screen requires additional cleaning, use premoistened antistatic wipes or an antistatic screen cleaner.

Cleaning the keyboard

WARNING! To reduce the risk of electric shock or damage to internal components, do not use a vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on the keyboard surface.

Clean the keyboard regularly to prevent keys from sticking and to remove dust, lint, and particles that can become trapped beneath the keys. A can of compressed air with a straw extension can be used to blow air around and under the keys to loosen and remove debris.

Traveling and shipping

The computer is built to go with you. For best results, follow the traveling and shipping tips described here:

●To prepare the computer for traveling and shipping, follow these steps:

1.Back up your information.

2.Be sure that the optical drive and PC Card slot are empty.

CAUTION: To reduce the risk of damage to the computer, damage to a drive, or loss of information, remove discs from a drive before removing the drive from a drive bay, and before shipping, storing, or traveling with a drive.

3.Turn off and then disconnect all external devices.

4.Shut down the computer.

●Take along a backup of your information. Keep the backup separate from the computer.

●When traveling by air, carry the computer as hand luggage, and do not check it in with the rest of your bags.
