Electronic device, electronic device management system, control method of electronic device, control method of electronic device management system, and storage medium

A method for controlling an electronic device configured to operate in one of a first power mode and a second power mode during which power consumption is lower than during the first power mode, the method comprising:

• measuring power consumption of the electronic device in the first power mode;
• calculating power consumption of the electronic device in the second power mode;
• and
• calculating total power consumption of the electronic device by adding the measured power consumption and the calculated power consumption.

A method for an electronic device management system having at least one electronic device and a management apparatus connected to be communicable with each electronic device via a network to manage each electronic device, where each electronic device is configured to operate in one of a first power mode and a second power mode during which power consumption is lower than during the first power mode, the method comprising:

• measuring, using the at least one electronic device, power consumption of the at least one electronic device in the first power mode;
• notifying, using the at least one electronic device, the management apparatus of measured power consumption information as power consumption notification;
• collecting, using the management apparatus, power consumption of the at least one electronic device in the first power mode measured by the at least one electronic device;
• calculating, using the management apparatus, power consumption of the at least one electronic device in the second power mode;
• calculating, using the management apparatus, total power consumption for each electronic device by adding collected power consumption and calculated power consumption for each electronic device.
