Abstract:
Provided is an information processing apparatus including: a power supply control portion that performs control of a power supply; a detection signal emitting portion that, when a connection of an external power source is detected in an operation stand-by state in which power consumption is suppressed and an operation is on stand-by, emits a detection signal only for a certain time period, in accordance with the detection; and a power supply portion that supplies power to the power supply control portion based on the detection signal emitted by the detection signal emitting portion and also stops the power supply to the power supply control portion after a certain time period elapses from the connection in the operation stand-by state.
