My computer does not shut down
You are recommended to shut down your computer using the Turn Off command on the Windows
®
Start
menu. Using other methods, including those listed here, may result in loss of unsaved data. If the Turn Off
command does not work properly, proceed as follows:
Press <Ctrl>+<Alt>+<Delete>. If you have not changed the default settings, you will enter the Task
Manager, where you can close any application that cannot close normally, and restart your system.
If this does not work, press <Alt>+<F4> to get to the Turn off computer screen, from where you can
shut down or restart your computer.
If this does not work, press the power button and hold it for at least four seconds.
This turns off the power.
Unplug the computer from the AC adapter and remove the battery pack from your computer.
My computer locks up
If you suspect one application is locking your system, you can try to stop it. To do this, press
<Ctrl>+<Alt>+<Delete> simultaneously. If you have not changed the default settings, you will enter the
Task Manager. Select the application or process that is locking your system, and then click End Task.
If the above method does not work or you do not know which application is locking your system, restart
the computer. On the Windows
®
taskbar, click the Start button, click Turn Off Computer, and then
select Turn Off.
If the above method does not work, press the power button and hold it for at least four seconds. This
turns off the power.
If your computer locks up while playing a CD-ROM, stop the CD-ROM, and shut down the computer by
pressing <Alt>+<F4> and clicking Turn Off in the Turn off computer screen.
