Information processing apparatus with power control unit, control method therefor, and storage medium storing control program therefor

摘要

An information processing apparatus that is capable of reducing power consumption. A power supply unit supplies electric power to devices including first and second devices of the apparatus. A power-state-switching unit switches a power state of the apparatus among a first power state in which the power supply unit supplies power to the devices, a second power state in which the power supply unit does not supply power to the first device without supplying power from a secondary battery to the devices, and a third power state in which the secondary battery supplies power to the second device. A control unit controls so that the secondary battery is charged by the power supplied from the power supply unit in the first power state, and to control so that the secondary battery is not charged by the power supplied from the power supply unit in the second and third power states.

主权项

1. An information processing apparatus that operates in a first power state, a second power state of which electric energy consumption is smaller than the first power state, or a third power state of which electric energy consumption is smaller than the second power state, comprising:
a power supply unit configured to supply electric power to devices including first and second devices of the information processing apparatus; a secondary battery configured to supply charged power to a part of the devices; a power-state-switching unit configured to switch a power state of the information processing apparatus among the first power state in which said power supply unit supplies power to the devices, the second power state in which said power supply unit does not supply power to the first device without supplying power from said secondary battery to the devices, and the third power state in which said secondary battery supplies power to the second device; and a control unit configured to control so that said secondary battery is charged by the power supplied from said power supply unit in the first power state, and to control so that active charging of the secondary battery is stopped upon detection of a condition causing a shift to the second power state regardless of a charge state of the secondary battery.
