Abstract
An apparatus and a method of detecting the capacity of the standby power. First, the components that are supplied with working voltage from the standby power are switched to the main power by a switch circuit. Then a control unit activates a dummy-loading circuit, thereby a coupling a loading device to the standby power. A voltage monitoring circuit monitors variations of the standby power to judge the capacity of the standby power, by which the switch circuit decides whether the standby power is activated or not. When detecting the capacity of the standby power, a switch circuit is needed to prevent variations of the standby power from affecting the normal operation of the essential circuit, and the standby power is supplied as operating power.
