Abstract
An electronic device for reducing power consumption of a computer motherboard is disclosed. The electronic device enables the computer motherboard to compel interruption of power supply to a south bridge chip and a super input output (SIO) chip of the computer motherboard so as to save power while the computer motherboard is waiting for receipt of a Wake-on-LAN packet. A network chip of the computer motherboard sends a signal to the power-saving electronic device as soon as a Wake-on-LAN event occurs, such that a standby power is electrically connected to the south bridge chip and the SIO chip by the electronic device. The computer motherboard equipped with the electronic device is capable of executing Wake-on-LAN function while compelling interruption of power supply to the south bridge chip and the SIO chip in a power-saving state.
