A power control device includes a power unit generating power to be supplied to a target device, from external power, an operating unit receiving operation of power on and power off by a user, a nonvolatile memory unit storing information, and a power control unit turning off, when the operating unit has received power-off operation, power supply to the target device in a predetermined sequence for the target device and records the fact that power has been turned off normally in the nonvolatile memory unit. When external power supply is started, the power control unit turns on the power supply to the target device when having determined that external power supply was stopped due to a certain cause, or does not turn on the power supply to the target device when having determined that external power supply was stopped due to a cause other than the certain cause. |

1. A power control device comprising:
a power unit that generates power to be supplied to a target device, from external power; an operating unit that receives operation of power on and power off by a user; a nonvolatile memory unit that stores therein information; and a power control unit that turns off, when the operating unit has received operation of power off, supply of the power to the target device in a predetermined sequence for the target device and records a fact that power has been turned off normally in the nonvolatile memory unit, wherein when supply of the external power is started, the power control unit
determines whether the supply of the external power was stopped due to a certain cause when the fact that the power has been turned off normally is not recorded in the nonvolatile memory unit, andturns on the supply of the power to the target device when the power control unit has determined that the supply of the external power was stopped due to the certain cause, ordoes not turn on the supply of the power to the target device when the power control unit has determined that the supply of the external power was stopped due to a cause other than the certain cause. |
