Troubleshooting Your Notebook

The power management setting is not responding.
Your notebook’s operating system may become unstable if it is interrupted or if
you attempt to make changes before the notebook completely enters a lower
power state, such as Hibernate.
❑
To restore the notebook to its normal operating stability:
1
Close all open applications.
2
Restart the notebook by clicking Start on the Windows® taskbar and
selecting Shut Down. Use the drop-down arrow to select Restart, and
click OK.
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.
Why does the System Properties dialog box display a slower CPU speed than
advertised?
❑
Your computer uses speed-controlling technology. The System Properties
dialog box may display the CPU’s current speed rather than the maximum
speed.
✍
If this procedure does not work, press and hold the power button for four seconds or
longer to shut down the notebook.
