1. An information processing apparatus comprising:
a power supply;
an interface;
a detector configured to detect at least one of a voltage value and a current value on an electric power line that connects the power supply and the interface; and
a controller configured to notify a swap request for swapping electric power roles with an external device to the external device via the interface,
wherein the electric power roles include a power source for supplying electric power, and a power sink for receiving electric power, and
in a case where a detection value of the detector indicates an abnormal value while the information processing apparatus works as the power source that supplies electric power to the external device via the interface, the controller notifies the swap request to the external device in order to switch the electric power role of the information processing apparatus from the power source to the power sink.
