Troubleshooting Your Notebook

My notebook is unstable.
Your notebook’s operating system may become unstable if a lower power state,
such as Hibernate, is initiated then changed before the notebook completely
enters the lower power state.
To restore the notebook to its normal operating stability:
1 Close all open applications.
2 Restart the notebook 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 notebook.
The sound of my notebook’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 CPU: Performance 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 notebook.
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.
