Heat and Product Ventilation
Danger:
Computers, AC adapters, and many accessories can generate heat
when turned on and when batteries are charging. Notebook computers
can generate a significant 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. Your computer generates some heat during
normal operation. The amount of heat depends on the amount of system
activity and the battery charge level. Extended contact with your body,
even through clothing, could cause discomfort or even a skin burn.
Periodically take breaks from using the keyboard by lifting your hands
from the palm rest; and be careful not to use the keyboard for any
extended length of time.
Do not operate your computer or charge the battery near flammable
materials or in explosive environments.
