A device includes a load test unit that determines whether to permit startup of the device using power of a battery supplying power to the device, and a control unit that starts up the device in a case where it is determined to permit startup of the device using the battery and a first voltage is requested of a power supply apparatus to restrict power received from the power supply apparatus. The control unit cancels the restriction of the received power in a case where a notification of completion of connection is received from the power supply apparatus, after the device is started up and a second voltage is requested of the power supply apparatus.
