„ 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:
ƒ 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.
ƒ Do not operate your computer or charge the battery near flammable
materials or in explosive environments.
ƒ Ventilation slots, fans and/or heat sinks are provided with the product
for safety, comfort, and reliable operation. These features might
inadvertently become blocked by placing the product on a bed, sofa,
carpet, or other flexible surface. Never block, cover, or disable these
features.
