摘要
A computer wake up circuit includes a first control circuit and a second control circuit. The first control circuit has an input terminal configured to receive a first control signal from a first serial device, and an output terminal coupled to a south bridge which is capable of waking up a computer. The second control circuit has an input terminal respectively coupled to a second serial device and an I/O controller, and an output terminal coupled to the south bridge. The second control circuit receives a second control signal from the second serial device. The first and second control circuits respectively outputs a wake up signal to the south bridge to wake up the computer according to the control signals. The I/O controller communicates with the second serial device through the second control circuit, and outputs other control signals to control operations of the second serial device.
