摘要 |
According to an embodiment, a power control device includes a storage unit, a monitor, a determining unit, and a controller. The storage device stores a look-up table, which includes relationship between needed power consumptions and start-up conditions of an electronic device including a plurality of modules. The start-up condition of the electronic device is determined from the needed power consumption in the look-up table and specifies a power on/off status of the modules in the electronic device. The monitor monitors a voltage or available power supplied by a power source when the electronic device is activated. The determining unit determines a start-up condition corresponding to needed power consumption, which corresponds to the voltage or available power monitored by the monitor, with reference to the table. The controller sets a start-up condition of the electronic device to start up the electronic device in the start-up condition determined by the determining unit. |

1. A power controller in an electronic device, comprising:
a monitor that monitors a voltage or available power supplied by a power source when the electronic device is activated; a determining unit configured to determine a start-up condition corresponding to needed power consumption, which corresponds to the voltage or the available power monitored by the monitor; a controller that sets start-up condition of the electronic device to start up the electronic device in the start-up condition determined by the determining unit; a receiving unit configured to receive a wakeup event signal of exiting a sleep mode in which the number of modules that is included in the electronic device and that is supplied with power is limited to a predetermined number and an operation of the electronic device is stopped, wherein when the receiving unit receives the wakeup event signal, the determining unit determines a condition corresponding to the power monitored by the monitor, and the controller sets a start-up condition of the electronic device to start up the electronic device in the condition determined by the determining unit. |
