What do I do if my computer stops responding?
It is best to turn off your computer using the Shut Down Computer option on the Microsoft ® Windows ® Start menu, located
on the taskbar. Using other methods, including those listed below, may result in loss of unsaved data.
 Click Start on the Windows ® taskbar, select Shut Down, select Shut Down again, and then click OK.
 If your computer does not turn off, press the Ctrl+Alt+Delete keys simultaneously. When the Windows Security
dialog box appears, click Shut Down from the Shut Down menu.
 If your computer still does not turn off, press and hold the power button or slide and hold the power switch until the
computer turns off.
 If your computer stops responding while playing a CD or DVD, press the Ctrl+Alt+Delete keys simultaneously. You
can turn off the computer from the Windows Security dialog box.
Pressing the Ctrl+Alt+Delete keys simultaneously or turning off the computer with the power button or switch
may cause loss of data.
 Remove the AC adapter and battery.
