Electronic apparatus and system for placing plurality of devices into corresponding power save modes according to priority level

An electronic apparatus linked to a management server via a network, comprising:

• a plurality of devices;
• a detecting section configured to detect execution of a function of the plurality of devices and identify a number of executions of the function;
• an obtaining section configured to obtain, for each device of the plurality of devices, a cumulative number of executions since a predetermined reference time;
• a transmitter configured to transmit the cumulative number of executions of said each device to the management server;
• a receiver configured to receive a power save mode for said each device from the management server, the power save mode being determined by the management server based on the cumulative number of executions of said each device;
• and
• a controller configured to control each device of the plurality of devices based on the power save mode for said each device;
• wherein
• the power save mode includes a power save condition corresponding to a priority level of said each device, a satisfaction of the power save condition causing said each device to shift to a power save status, the power save condition indicating a time period for said each device to be idle in a normal operation status before being shifted to a power save status;
• and
• of all power save modes of the plurality of devices, the longer is the time period indicated by the power save condition of a power save mode, the higher is the priority level of the corresponding device.

An electronic system in which an electronic apparatus and a management server are linked through a network, wherein the electronic apparatus includes:

• a plurality of devices;
• a detecting section configured to detect execution of a function of one of the plurality of devices and identify a number of executions of the function;
• an obtaining section configured to generate, for each device of the plurality of devices, a cumulative number of executions of said each device based on the number of executions of the function, and holding the cumulative number of executions;
• a transmitter configured to transmit the cumulative number of executions of said each device to the management server;
• a receiver configured to receive a power save mode for said each device from the management server;
• and
• a controller configured to control each device of the plurality of devices based on the power save mode for said each device;
• wherein the management server includes:
• a receiver configured to receive the cumulative number of executions from the electronic apparatus;
• a priority determining section configured to determine a priority level of each of the plurality of devices such that one of the plurality of devices having higher frequencies of use are given higher priority levels, and to then generate a list of priority levels of the plurality of devices;
• and
• a transmitter holding a plurality of power save modes and configured to select one of the plurality of power save modes in accordance with the priority level of one of the plurality of devices;
• wherein
• each power save mode of the plurality of power save modes includes a power save condition corresponding to the priority level of the device having said each power save mode, a satisfaction of the power save condition causing the device having said each power save mode to shift to a power save status, the power save condition indicating a time period for the device having said each power save mode to be idle in a normal operation status before being shifted to the power save status;
• and
• of the plurality of power save modes, the longer is the time period indicated by the power save condition of a power save mode, the higher is the priority level of the device having the power save mode.
