Disclosed is an apparatus and method of power-saving and wake-up, which is not only used to reduce the power consumption of a system of electronic equipment, but also allow the system to immediately return to normal operation according to the requirement. The apparatus for power-saving and wake-up includes a first detector, a second detector, a decoder and a third detector. The method for power-saving and wake-up includes detecting a cable signal, a clock pair signal and a differential pair signal. When one of the detected signals is unusual, the system soon turns off the unusual channel power and implement the procedures for power saving and operates under the power saving mode, which can realize the effect of power saving and low power consumption. The method for power-saving and wake-up includes detecting the cable signal, the toggling and frequency of the clock signal and the synchronizing signals of the system.
