ABSTRACT:
A control apparatus for turning off a computer system is provided which protects a display from damage. Also, methods for turning off a computer system are provided which protect a display from damage. The control apparatus and methods for turning off power supplied to a computer system having a display provide that power supplied to the display is turned off first and power supplied to the entire computer system is turned off last. A first control unit outputs a first signal to initiate cut off of power supplied to the display if a power switch is turned off and also outputs a second signal to cut off power supplied to the entire computer system after power to the display has been cut off. A second control unit receives the first signal and outputs a third signal to cut off power supplied to the display in response to the first signal.
