INFORMATION PROCESSING APPARATUS CAPABLE OF REDUCING POWER CONSUMPTION, AND CONTROL METHOD AND STORAGE MEDIUM THEREFOR

摘要

An information processing apparatus capable of changing a state of power supply to respective parts of the apparatus with less user operation. When a sleep recovery button is depressed in a power saving mode, a button depression time is measured, and whether a length of the measure depression time exceeds a threshold value is determined. If the depression time exceeds the threshold value, a normal power mode is selected as power mode after transition. If the depression time does not exceed the threshold value, another power saving mode is selected as power mode after transition. According to the selected power mode, a state of power supply to respective parts of the apparatus is changed.

主权项

1. An information processing apparatus that has a plurality of power modes including a normal power mode and at least one power saving mode and that performs a mode changeover among the plurality of power modes, thereby changing a state of power supply to respective parts of the apparatus, comprising:
an operation unit configured to be operated to make a transition from one of the at least one power saving mode to another power mode; a measurement unit configured to measure an operation time of said operation unit; a selection unit configured to select a power mode after transition according to a length of the operation time of said operation unit measured by said measurement unit; and a control unit configured to change the state of power supply to respective parts of the apparatus according to the power mode selected by said selection unit.
