Troubleshooting Your Computer
195
My computer is unstable.
Your computer’s operating system may become unstable if a lower power state, 
such as Hibernate, is initiated then changed before the computer completely 
enters the lower power state. 
To restore the computer to its normal operating stability: 
1
Close all open applications.
2
Restart the computer by pressing the Ctrl+Alt+Delete keys simultaneously, 
and clicking Restart on the Windows Security window.
3
If this procedure does not work, press and hold the power button for four 
seconds or longer to shut down the computer.
The sound of my computer’s fan is too 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 Battery 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, System Properties may display the CPU’s current speed 
instead of the maximum advertised speed.
