Abstract:
A power control circuit and a power control method applied to a computer system are disclosed. A regulator receives a first voltage, the regulator converting the first voltage to an embedded controller voltage when the regulator is enabled. A detecting and controlling circuit receives the first voltage and the button signal, and the regulator is enabled when the detecting and controlling circuit detects the button signal. An embedded controller connects to the regulator for receiving the embedded controller voltage and outputting the plurality of power control signals. The embedded controller sends a power on signal to the detecting and controlling circuit to keep the regulator enabled.
