Troubleshooting
Restarting the Computer
You may have to restart (reboot) your computer on some occasions when an
error occurs and the program you are using hangs up.
If you are sure the operation has stopped and you cannot use the “restart”
function of the operating system, restart the computer by any one of these
methods:
 Press Ctrl+Alt+Del on the keyboard.
 If the above action does not work, press and hold the power button for
more than 5 seconds to force the system to turn off. Then turn on the
power again.
