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.
• 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.
