Abstract
An apparatus includes a control unit configured to switch a power state among a first power state, a second power state, and a third power state, the first power state being a state where a device driver is loaded and a device is usable, the second power state being a state where the device driver is unloaded and the device is unusable, the third power state being a state where the device driver is unloaded and the device is unusable, power consumption in the third power state being less than power consumption in the second power state. Based on reception of a predetermined signal in a case where the information processing apparatus is in the third power state, the control unit causes the power state to transition from the third power state to the second power state.
Claims15
An apparatus that controls a device via a device driver, the apparatus comprising:
- a reception unit configured to receive a predetermined signal;
- and
- a control unit configured to switch a power state among a first power state, a second power state, and a third power state, the first power state being a state where the device driver is loaded and the device is usable, the second power state being a state where the device driver is unloaded and the device is unusable, the third power state being a state where the device driver is unloaded and the device is unusable, power consumption in the third power state being less than power consumption in the second power state,
- wherein, based on reception of the predetermined signal in a case where the apparatus is in the third power state, the control unit causes the power state to transition from the third power state to the second power state.
A method for an apparatus that controls a device via a device driver, the method comprising:
- receiving a predetermined signal;
- switching, under a first condition, a power state from a first power state to a second power state, the first power state being a state where the device driver is loaded and the device is usable, the second power state being a state where the device driver is unloaded and the device is unusable;
- switching, under a second condition, the power state from the second power state to a third power state, the third power state being a state where the device driver is unloaded and the device is unusable, power consumption in the third power state being less than power consumption in the second power state;
- and
- causing the power state to transition from the third power state to the second power state based on reception of the predetermined signal in a case where the apparatus is in the third power state.
