Claim 12:
13. A method of operating a communication device insertable into an external electronic device, the method comprising:
receiving a first signal from a processor of the external electronic device through a signal line;
receiving a second signal generated based on a discharging power flowing along a power line to a ground through at least one second conductor when a first conductor is electrically connected to at least one second conductor according to a fastening between the communication device and the external electronic device;
outputting, based on the first signal and the second signal, a control signal to a converter circuit for controlling the converter circuit; and
refraining from outputting the control signal for controlling the converter circuit, based on receiving a third signal generated during electrical disconnection between the first conductor and at least one second conductor while receiving the first signal through the signal line.
