Power saving apparatus and method
A power saving apparatus (20) is interposed between a power supply unit (10) and an electronic device (30). The power saving apparatus includes a switching component (210), a controlling circuit (230) controllable by the electronic device, and a switching circuit (220) controllable by the controlling circuit and the switching component. The controlling circuit receives an “idle” signal from the electronic device and controls the switching circuit to cut off the power supply to the electronic device according to the “idle” signal. The switching component produces an “awakening” signal to control the switching circuit to resume the power supply to the electronic device. A related power saving method is also introduced.
