Mechanical Problem - FAN / Thermal

Why is the cooling fan always ON and the temperature high?

1. Make sure that the FAN works when the CPU temperature is high and check whether there is

air ow from the main air vent.

2. If you have many applications running (see taskbar), close them to decrease system load.

3. The problem may also be caused by some viruses, use anti-virus software to detect them.

4. If none of the above help, try restoring your system using the recovery partition or DVD.

(IMPORTANT: You must backup all your data to another location before recovering.)

(CAUTION: Do not connect to the Internet before you have installed an anti-virus software

and Internet rewall to protect yourself from viruses.)
