Abstract: PROBLEM TO BE SOLVED: To provide a computer system, a computer device, a feeding control method in the computer device, capable of suitably controlling a power supply corresponding to a type of usage. SOLUTION: This computer system 10 is provided with a PC body 20, and a digitizer 30. A type of usage of the computer system 10 is detected, and when the type of usage is the specified type of usage, for example, a type of usage pattern mainly using the digitizer 30, a shifting power saving mode is decided according to attaching/detaching of a AC adapter, the remaining amount of a battery, the upload frequency of data from the digitizer 30 and the like. When the PC body 20 is in a power saving mode and an upload request of data from the digitizer 30 side exists, the PC body is returned to be a normal mode, and made to be the power saving mode again after the completion of uploading.

Abstract: A data processing system capable of specifying impeding factors that impede power savings is disclosed. The data processing system includes a central processing unit, an operation mode detection unit, and an impeding factors specifying unit. The central processing unit has multiple operation modes, and each of the operation modes has a different rate of power consumption. The operation mode detection unit detects an operation mode of the central processing unit. Based on a history of operation modes of the central processing unit that was detected by the operation mode detection unit, the impeding factors specifying unit specifies a device that considered as an impeding factor to power savings for the data processing system.

Abstract: There is provided an information processing device capable of identifying an inhibiting factor inhibiting power saving. The information processing device has a plurality of operation modes using different power consumptions and includes: a main device for changing the operation mode according to a reque st from a sub-device; an operation mode detection section for detecting the operation mode of the main device; an inhibiting factor identification secti on for identifying the sub-device which has transmitted a request to the main device or the processing of the main device performed in response to the request from the sub-device as an inhibiting factor according to the history of the operation mode of the main device detected by the operation mode detection section.
