To restore the computer to its normal operating stability
1 Close all open programs.

Windows Task Manager dialog box appears, and you can restart the
computer from the Shut Down menu.
3 If this procedure does not work, press and hold the power button to turn off
the computer.
Why is the sound of my computer’s fan so loud?
Use the PowerPanel™ utility to change the Thermal Control Strategy setting to
Quiet. This setting slows down the CPU speed. See PowerPanel Help for more
information.
To reduce fan noise
1 Right-click the CPU icon on the taskbar, and select Edit/Create
Profiles. The AC Power Profile Editor window appears.
2 Double-click System to open the file if it isn’t already opened.
3 Double-click Thermal Control Strategy - Performance, and select Quiet.
4 Restart your computer.
Why does the System Properties dialog box display a slower CPU speed than
advertised?
This is normal. Because your computer’s CPU utilizes a type of CPU speed
controlling technology for power conservation purposes, System Properties may
display the CPU’s current speed instead of the maximum speed.
