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

NOTICE: To prevent damage to the antiglare 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 touch pad and the surrounding palm rest.
