The CPU cooling fan keeps the central processing unit at a
temperature suitable for optimum performance by drawing
outside air into the computer.
The battery pack contains the battery. For information about
replacing the battery, see
page 131.
The battery release latch secures the battery to the
computer, preventing the battery from dislodging from the
computer case.
To prevent possible overheating of the CPU, make sure the
cooling fan's air intake is not blocked. The fan draws in air by
creating a vacuum. If the fan is blocked, it could cause the
CPU to run at a lower performance level or cause the computer
to shut down. Loose items such as notebook and tissue paper,
plastic wrappers, or other similar materials can block the air
intake, preventing air from reaching the CPU. Do not use the
computer on surfaces with objects that can be drawn in by the
cooling fan.
