1. An information processing apparatus comprising:
a power source;
an electric power line;
an interface configured to be connected with the power source via the electric power line, the interface including:
a first signal line for management regarding electric power supply from the power source via the electric power line; and
a second signal line different from the first signal line, the second signal line being for data communication with an external device via the interface;
a detector configured to detect at least one of a voltage value and a current value on the electric power line; and
a controller configured to transmit warning information to the external device via the first signal line of the interface, in a case where a detection value of the detector indicates an abnormal value while electric power is supplied to the external device via the interface,
wherein the first signal line is provided to decide what electric power role is set for the information processing apparatus,
the electric power role is either a source that is an electric power role for supplying electric power or a sink that is an electric power role for receiving electric power, and
in a state where the electric power role of the information processing apparatus is set to the source, the controller is configured to transmit the warning information to the external device set to the sink as an electric power role of the external device, in the case where the detection value of the detector indicates the abnormal value; and
wherein the controller is configured to transmit, as the warning information, information indicating that electric power supplied to the external device via the interface is to be restricted, in the transmission of the warning information, and
wherein the controller is configured to transmit, as the warning information, information indicating a grace period of time to start restriction of electric power supplied to the external device via the interface, in the transmission of the warning information.
