Abstract:
An information processing apparatus includes a main storage unit and a primary computing unit. When a power-save mode is set, power supply to the main storage unit is being continued while power supply to the primary computing unit is stopped. The primary computing unit includes an operation status information processing unit to store operation status information of the primary computing unit when shifting to the power-save mode; a storing destination information processing unit to store storing-destination information indicating a storage area of the operation status information; a power-supply stop control unit to stop power supply to the primary computing unit after storing the operation status information and storing-destination information; a return operation identifying unit to confirm return operation identification information and to initialize the primary computing unit after power supply to the primary computing unit is resumed; and an operation status restoring unit to read the operation status information.
