An electronic device includes a first mode, a second mode, a mode transition accepting unit, a state confirmation unit, and a transition determination unit. The mode transition accepting unit is configured to accept from a plurality of demanding sources a transition demand to transition from the first mode to the second mode. The state confirmation unit is configured to confirm a device state of the electronic device. The transition determination unit is configured to determine whether or not a transition from the first mode to the second mode is possible based on a demanding source of the transition demand accepted by the mode transition accepting unit, and the device state confirmed by the state confirmation unit. When the device state is a predetermined device state, the transition determination unit makes a determination that the transition is possible for some of the plurality of demanding sources that issued the transition demand and not possible for others of the plurality of demanding sources that issued the transition demand. |

1. An electronic device comprising a processor, wherein the processor operates to implement:
a mode transition accepting unit that accepts, from a plurality of demanding sources, a transition demand to transition from a first mode to a second mode; a state confirmation unit that confirms a device state of the electronic device; and a transition determination unit that determines whether or not a transition from the first mode to the second mode is possible based on one of the plurality of the demanding sources that issued the transition demand accepted by the mode transition accepting unit, and the device state confirmed by the state confirmation unit; wherein in the first mode, the electronic device operates at a predetermined electric power; in the second mode, the electronic device operates at an electric power lower than the first mode; when the device state is a single, specific device state that is a predetermined device state, the transition determination unit makes a separate, independent determination, for each of the plurality of demanding sources, that the transition is possible for some of the plurality of the demanding sources that issued the transition demand and the transition is not possible for others of the plurality of the demanding sources that issued the transition demand; and the predetermined device state is an error state in which the state confirmation unit has not determined that the device state is a severe device error. |
