ABSTRACT:
A method and apparatus for automatically undertaking power reduction of a monitor in a computer system make use of the fact that, when the computer system is active, synchronization pulses will be transmitted to the monitor. In the method and apparatus herein, it is insured that when the computer system is inactive, transmission of those synchronization pulses ceases. Within the monitor, the reception of these synchronization pulses is detected, and in the absence of synchronization pulses, steps are taken to reduce the power consumption by the monitor. Power can be discontinued to different portions of the monitor as the length of time for which the synchronization pulses are absent increases.
