Shutting Down Your Computer 29
About the Power Switch
If your system “locks up” or “crashes,” press and hold the power switch
for four seconds to force your system to power off. You may need to
repeat this procedure. See “Locating Controls and Connectors” on page 5
for the power switch’s location.
✍
You can also shut down your computer using the (Power) button on the keyboard.
Pressing this button causes the system to perform a shutdown but does not give you any of
the other options available on the Windows
® Shut Down menu.
