Product Information Guide.
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 and to remove any
dirt or lint from the display.
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.
•
Moisten a soft, lint-free cloth with either water or a display cleaner. Do not use alcohol or an ammonia-
based cleaner. Wipe the display gently working from the center to the edges until it is clean and any
fingerprints are removed. Do not use excessive pressure.

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.
