| 发明名称 | Data processing apparatus capable of controlling power supply, control method therefor, and storage medium | ||
| 摘要 | A data processing apparatus that has first to fourth power modes in which power consumption becomes larger in this order, and is capable of changing into a mode selected and set by a user. A receiving unit receives the instruction for bringing the data processing apparatus into the third power mode or the fourth power mode. A first transition unit brings, when the apparatus is working in the second power mode, the apparatus into the first power mode in response to the receiving unit receiving the transition instruction. A determination unit determines which mode the apparatus is to be brought into between the third power mode and the fourth power mode in response to the first transition unit bringing the apparatus into the first power mode. A second transition unit brings the apparatus into a power mode determined by the determination unit. | ||

| 主权项 | 1. A data processing apparatus, comprising: a process unit configured to process data; a storage unit configured to store information indicative of a state into which the data processing apparatus is to be brought in a case where an instruction to turn off a power source of the data processing apparatus is received; and a power control unit configured to bring, in a case where the instruction to turn off the power source of the data processing apparatus is received when the data processing apparatus is in a first power state in which supply of power to said process unit is stopped, the data processing apparatus from the first power state into a second power state in which power is supplied to said process unit, wherein in a case where the data processing apparatus has been brought into the second power state by said power control unit, said process unit determines a state into which the data processing apparatus is to be brought based on the information stored in said storage unit, and said power control unit bring the data processing apparatus into the state determined by said process unit. | ||
