1. A method comprising:
receiving, by a processor in communication with an internal battery, an indication the internal battery is receiving power from an external power supply;
determining, by the processor, a first average output current of the internal battery; and
generating, by the processor, an error indicating the internal battery receives insufficient power from the external power supply,
wherein the error indicates the external power supply is faulty in response to the first average output current alternating between a positive and negative polarities while receiving power from the external power supply.
