According to one embodiment, an electronic device includes a power delivery controller and an embedded controller. The power delivery controller supplies a first signal to the embedded controller when reception of a power from an external device is started, and supplies a second signal to the embedded controller when a first value of the power from the external device is changed. The embedded controller acquires first data from the power delivery controller when the first signal is supplied in an activation time, acquires a second value of the power to be received from the external device from a power circuit, and acquires second data from the power delivery controller when the first value indicated by the first data is different from the second value.
