Abstract
A power control apparatus is disclosed. The power control apparatus includes a temperature sensor, a level-controlling unit, a reset unit and a first voltage converter. The temperature sensor is for sensing an operation temperature of a computer system and accordingly outputs a sensing signal. The level-controlling unit is for deciding whether or not to output a control voltage according to the sensing signal. The reset unit is for producing a reset signal according to a plurality of reference voltages generated by dividing the power voltage and using the control voltage to adjust the levels of the reference voltages. The first voltage converter is for producing a start signal according to the reset signal, wherein the start signal is for enabling the embedded controller.
