Resetting the Computer
You may have to reset (reboot) your computer on some occasions when
an error occurs and the program you are using hangs up.
If the computer operation seems to hang up, first wait. It is possible that
the computer is processing data. Periodically check the hard disk drive
in-use indicator, if it flashes irregularly, the program may be accessing
data and preventing you from using the keyboard. If you are sure the
operation has stopped and you cannot use the “restart” function of the
operating system, reset the computer.
Reset 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.
CAUTION: Resetting will cause any unsaved data to be lost.
