  • Patent number: 8854838
    Abstract: An electronic device includes a power supply system and a load circuit connected to the power supply system. The load circuit mutually switches between the first mode and the second mode. In the first mode, the load circuit operates with electric power supplied from the power supply system. On the other hand, in the second mode, the load circuit is brought into the state where the electric power does not need to be supplied from the power supply system. In response to the fact that the mode of the load circuit is switched from the first mode to the second mode, a power supply control device causes an AC/DC converter to stop.
