Abstract
0An apparatus and method for saving power by cutting off the power supplied to a monitor when an input signal does not exist for a given time period. An input signal is checked to see if it is sensed from input means of the monitor. A power circuit is operated each time the input signal is sensed and simultaneously a time value for performing a power saving mode is set in a reference buffer. The receiving time of the input signal is counted by updating the time value set in the reference buffer each time an interrupt signal is received from a timer, and then the time value of the reference buffer is read. If the input signal is not sensed until a setting time elapses, an operating voltage of the monitor is cut off by controlling the operation of the power circuit.
