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 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.
• 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.
