Heat and product ventilation
DANGER
Computers, ac power adapters, and many accessories can generate heat when turned on and when
batteries are charging. Notebook computers can generate a signicant amount of heat due to their
compact size. Always follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the palm rest, and some
other parts may become hot. Avoid keeping your hands, your lap, or any other part of your
body in contact with a hot section of the computer for any extended length of time. When you
use the keyboard, avoid keeping your palms on the palm rest for a prolonged period of time.
