COMPUTER SYSTEM FOR SAVING POWER CONSUMPTION OF A STAND-BY/POWER-OFF STATE AND METHOD THEREOF

摘要

A computer system consists of a plurality of electronic elements and a switch control circuit. The switch control circuit controls the computer system to enter a stand-by/power off state from a normal state when the computer system receives a stand-by/power off command under the normal state, and stops outputting a stand-by power having at least one stand-by voltage level to at least one part of electronic elements among the plurality of electronic elements. At this time, the computer system has entered a simulated mechanical off state from the stand-by/power off state. A number of electronic elements supplied by the stand-by power when the computer system lies under the simulated mechanical off state is smaller than a number of electronic elements supplied by the stand-by power when the computer system lies under the stand-by/power off state.
