Abstract:
A controller determines a state of a switch unit based on a potential difference between a power supply side and a load side of the switch unit. Alternatively, when an electronic device is in a first operating state, the controller determines a state of the switch based on a result of a first detection unit. When the electronic device is in a second operating state that a power consumption of the device is lower than that in the first operating state, the controller determines the state of the switch based on a result of a second detection unit.
