Abstract
A device state control method for use in an information processing apparatus that has a body, a device connectable to the body, a storage portion which stores information of a state of power supply to the device, the device state control method including: determining whether the information of state of power supply stored in the storage portion is information of power-supply OFF state or not, after instructing to shift the state of the power supply to the device from the power-supply OFF state into a power-supply ON state; and starting the power supply to the device, when the information of power-supply OFF state is stored in the storage portion.
Claims12
A device state control method for use in an information processing apparatus that has a body, a device connectable to the body, a storage portion which stores information of a state of power supply to the device, the device state control method comprising:
- determining whether the information of state of power supply stored in the storage portion is information of power-supply OFF state or not, after instructing to shift the state of the power supply to the device from the power-supply OFF state into a power-supply ON state;
- and
- starting the power supply to the device, when the information of power-supply OFF state is stored in the storage portion.
An information processing apparatus comprising:
- a body;
- a device which is connectable to the body;
- a storage portion which stores information of a state of power supply to the device;
- determination unit which determines whether the information of state of power supply stored in the storage portion is information of power-supply OFF state or not, after instructing to shift the state of the power supply to the device from the power-supply OFF state into a power-supply ON state;
- and
- a controller which starts the power supply to the device, when the information of power-supply OFF state is stored in the storage portion.
An information processing apparatus comprising:
- a body;
- a device which is connectable to the body;
- a storage portion which stores information of a state of power supply to the device;
- an instruction unit which instructs to shift the power supply state of the device from a power-supply OFF state into a power-supply ON state;
- an acquisition unit which acquires the information of device power-supply state stored in the storage portion on the basis of the instruction;
- a determination unit which determines whether the information of device power-supply state acquired by the acquisition unit is information of power-supply OFF state or not;
- and
- a controller which starts the power supply to the device on the basis of the determination.
