Abstract:
1. An information processing apparatus which has an ordinary state and a power-saving state that has a power consumption lower than that of the ordinary state, the apparatus comprising: a body; a cover which is supported by the body, and capable of being opened and closed with respect to the body; a sensor to detect an open/close state of the cover; an electric power management controller to perform electric power management of the apparatus in accordance with the ordinary state and the power-saving state; a processor to (i) to the electric power management controller that processing for changing the apparatus to the power-saving state is performed since the cover is closed, if the sensor detects that the cover is closed and an action to be performed when the cover is closed indicates change to the power-saving state, (ii) request an operating system to change to the power-saving state, if the sensor detects that the cover is closed and the action to be performed when the cover is closed indicates the change to the power-saving state, and (iii) provide, to the electric power management module, a notice indicating changing of the apparatus to the power-saving state, when processing which is performed by the operating system to change the apparatus to the power-saving state is finished, wherein the electric power management controller turning on the apparatus in order to change the apparatus to the ordinary state, if the electric power management controller is notified that the processing for changing to the power-saving state is to be performed since the cover is closed and the sensor detects that the cover is opened, and wherein the electric power management controller performs an electric power management corresponding to the power-saving state according to the notice, if the electric power management controller is not notified that the processing for changing to the power-saving state is to be performed since the cover is closed, or if the electric power management controller is notified that the processing for changing to the power-saving state is to be performed and the sensor detects that the cover is closed.
