Troubleshooting
What should I do if my computer or software stops responding?
If your computer stops responding while a software application is running, press the Alt+F4 keys to close the application
window.
If the Alt+F4 keys do not work, click Start, the arrow next to the Lock button, and Shut Down to turn off your computer.
If your computer does not turn off, press the Ctrl+Alt+Delete keys and click the arrow next to the Shut down button
and Shut Down.
If the Windows Security window appears, click Shut Down.
!
Turning off your computer with the Ctrl+Alt+Delete keys or the power button may cause loss of unsaved data.
If your computer still does not turn off, press and hold the power button until the computer turns off.
Remove the AC adapter and battery pack.
Try reinstalling the software.
Contact the software publisher or designated provider for technical support.
