Information processing apparatus, control method therefor, and storage medium

摘要

An information processing apparatus to which an external device is attachable includes an initialization unit configured to, when the information processing apparatus is activated from a power-off state, execute initialization of the external device, and not to, when the information processing apparatus is returned from a power-saving state, execute the initialization of the external device.

1. An information processing apparatus to which an external device is attachable, the information processing apparatus comprising:
an initialization unit configured to, in a case where the information processing apparatus is activated from a power-off state, execute initialization of the external device attached to the information processing apparatus; a detection unit configured to detect an operation to turn off a power switch, a storing unit configured to store settings of a pre-set power state to which the information processing apparatus is to be shifted in a case where the operation to turn off the power switch is detected; a first acquisition unit configured to acquire information on the external device attached to the information processing apparatus before the information processing apparatus is shifted to the power-saving state; a storage unit configured to store the information acquired by the first acquisition unit; a second acquisition unit configured to acquire information on the external device attached to the information processing apparatus after the information processing apparatus is returned from the power-saving state; and a control unit configured to shift, in response to the detection of the operation to turn off the power switch, the power state of the information processing apparatus from a standby state to the pre-set power state, in a case where the information stored in the storage unit is consistent with the information acquired by the second acquisition unit, and to shift, in response to the detection of the operation to turn off the power switch, the power state of the information processing apparatus from the standby state to the power-off state, in a case where the information stored in the storage unit is inconsistent with the information acquired by the second acquisition unit, even if the power-saving state is set as the pre-set power state to which the information processing apparatus is to be shifted.
