Abstract: According to one embodiment, a power management module in an information processing apparatus is configured to execute a process of setting a power-down signal to a peripheral device in an active state in response to a power-down signal generation command, a process of setting the information processing apparatus in a sleep state in response to a sleep state transition request signal, a process of restoring the information processing apparatus to a working state in response to generation of a predetermined wakeup event, and a process of setting the power-down signal in an inactive state before a predetermined time has passed since the restoration of the information processing apparatus to the working state.

Abstract: According to one embodiment, an information processing apparatus includes a controller, a wakeup controller, a power source, an input controller, and a switch. The controller configured to perform communications with an external device. The wakeup controller configured to wake up a system in accordance with a request from the external device. The power source configured to generate a driving power to drive the controller and to supply the driving power to the controller. An input controller configured to output a signal according to an operation of an input device. The switch configured to instruct the power source to switch between supply and non-supply of the driving power when a predetermined signal is output from the input controller in a state in which the system is not woken up.
