My notebook stops responding or does not shut down.
It is best to shut down your notebook using the Shut Down command on the Windows Start menu. Using other methods,
including those listed here, may result in loss of unsaved data.
 Try restarting the notebook. On the Windows taskbar, click Start, select Turn Off Computer, and then click Turn Off.
 If your computer does not restart, press Ctrl+Alt+Delete simultaneously. When the Windows Task Manager
appears, select Shut Down and then Restart from the drop-down list.
 If the previous step does not work, press and hold the power button for at least four seconds. This turns off the
power.
 If your notebook stops responding while playing a CD or DVD, stop the CD/DVD, and restart the notebook. To
restart the notebook, press Ctrl+Alt+Delete simultaneously. When the Windows Task Manager appears, select Shut
Down and then Restart from the drop-down list.
 Unplug the notebook from the AC adapter and remove the battery pack from your notebook.

Pressing Ctrl+Alt+Delete simultaneously or turning off the notebook with the power switch may result in data loss in files
that are currently open.
