A power control circuit includes an input/output controller hub (ICH), and first to third metal-oxide-semiconductor field effect transistors (MOSFETs). A drain of the first MOSFET is connected to a standby power source through a first resistor. A gate of the first MOSFET is connected to a sleep control terminal of the ICH through a second resistor. A drain of the second MOSFET is connected to the drain of the first MOSFET through a third resistor. A gate of the second MOSFET is connected to a general purpose input/output terminal of the ICH through a fourth resistor. A source of the third MOSFET is connected to the standby power source. A gate of the third MOSFET is connected to the drain of the second MOSFET. A drain of the third MOSFET is connected to a power terminal of an onboard network interface card.
