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:
1Close all open applications.
2Restart the computer by pressing the Ctrl+Alt+Delete keys simultaneously,
and clicking Restart on the Windows Security window.
3If 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
1Right-click the Battery icon on the taskbar, and select Edit/Create Profiles.
The AC Power Profile - Editor window appears.
2Double-click System to open the file if it isn’t already opened.
3Double-click Thermal Control Strategy - Performance, and select Quiet.
4Restart 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.
