Patent ID: 8667307

Claim:
A power control circuit of a computer system, the power control circuit comprising: a regulator for receiving a first voltage, the regulator converting the first voltage to an embedded controller voltage when the regulator is enabled, wherein the regulator comprises a first resistance; a detecting and controlling circuit for receiving the first voltage and a button signal, and the regulator is enabled when the detecting and controlling circuit detecting the button signal, and the detecting and controlling circuit comprising: a second resistance; a third resistance; and a regulated circuit for converting the first voltage to an operated voltage, wherein the regulated circuit comprises: a parallel connection regulator, an anode of the parallel connection regulator connected to the ground, and a cathode of the parallel connection regulator outputting the operated voltage; a fourth resistance connecting the first voltage and the cathode of the parallel connection regulator; a fifth resistance connecting the cathode of the parallel connection regulator and a reference pin of the parallel connection regulator; and a sixth resistance connecting the anode of the parallel connection regulator and the reference pin of the parallel connection regulator; and an embedded controller connected to the regulator for receiving the embedded controller voltage and outputting the plurality of power control signals; wherein the embedded controller sending a power on signal to the detecting and controlling circuit to keep the regulator enabled.
