Abstract:
1. An information processing apparatus which is included in a group of plural information processing apparatuses, the information processing apparatus comprising: a setting information obtaining unit that obtains information regarding time to change a power supply state of the information processing apparatus; a control unit that, according to the obtained information, changes the power supply state of the information processing apparatus from a first power supply state where a communication function of the apparatus is inactivated to a second power supply state where the communication function is activated and, according to the obtained information, keeps the power supply state in the second power supply state; and a restoration cause detection unit that detects if a restoration cause exists, wherein the control unit changes the power supply state of the information processing apparatus from the second power supply state to the first power supply state according to the obtained information in response to the restoration cause detection unit not detecting that the restoration cause exists, and the control unit does not change the power supply state of the information processing apparatus from the second power supply state to the first power supply state in response to the restoration cause detection unit detecting that the restoration cause exists, and wherein the time to change the power supply state is set so that, at all times during a set power supply control mode for the group of the plural information processing apparatuses, at least one information processing apparatus, among the group of the plural information processing apparatuses, is in the second power supply state for a period of time.
