Disclosed is an electronic device comprising: a connection circuit configured to provide an electrical connection of an external power supply device; a processor electrically connected to the connection circuit; a memory operatively connected to the processor; and a reset circuit electrically connected to the connection circuit and operatively connected to the processor. The processor is configured to” transmit, to the reset circuit, an interrupt signal during a first time at least partially based on the identification of the connecting to the external power supply device through the connection circuit, and the reset circuit may be configured to: determine whether the interrupt signal is received within a second time after the connecting to the external power supply device through the connection circuit, and transmit, to the processor, a reset signal for a hardware reset of the processor based on the interrupt signal not being received within the second time.
