It is best to shut down your computer using the Turn Off Computer command on 
the Windows Start menu. Using other methods, including those listed here, may 
result in loss of unsaved data. 

❑

Try restarting the computer. On the Windows taskbar, click the Start button, 
click Turn Off Computer, and then click Restart.

❑

If you cannot restart as described in the preceding step, you can restart the 
computer by pressing the Ctrl+Alt+Delete keys at the same time.

❑

If the previous step does not work, press and hold the power button for at 
least four seconds. This turns off the power to the computer.

❑

If your computer stops responding while playing a CD or DVD, stop the 
CD/DVD, and restart the computer by pressing the Ctrl+Alt+Delete keys at 
the same time.

❑

Unplug the computer from the AC adapter and remove the battery pack from 
your computer.

Your computer’s operating system may become unstable if it is interrupted or if 
you attempt to make changes before the computer completely enters a lower 
power mode, such as Hibernate. 

❑

Close all open applications.

Restart the computer by pressing the Ctrl+Alt+Delete keys at the same 
time, and then selecting Restart from the drop-down list.

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

✍

If this procedure does not work, press and hold the power button for at least four 
seconds to shut down the computer.
