摘要: A power control apparatus is disclosed. The power control apparatus includes a temperature sensor, a first voltage converter, an over-temperature protection, a reset unit and a second voltage converter. The temperature sensor is for sensing a measured temperature to output a sensing signal. The first voltage converter converts the power voltage of a computer system into a first voltage. The over-temperature protection unit receives the first voltage and decides whether or not outputting the first voltage according to the sensing signal. When the reset unit has received the first voltage from the over-temperature protection unit, the reset unit decides whether or not to produce a reset signal according to the level of the power voltage. The second voltage converter is for producing a start signal to enable the embedded controller according to the reset signal.
