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.

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