Important information about your CPU cooling fan

The round cooling fan on the underside of your computer keeps the central processing unit at a temperature suitable for optimum performance by drawing outside air into the computer.

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.
