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.
