Kind Code:
B2
Abstract:
To provide an electronic device capable of stably executing normal shutdown processing.SOLUTION: An electronic device according to an embodiment that operates by power supply from a removable first battery and a rechargeable second battery includes a detection means, a switching means, and a first processing means. The detection means detects that a voltage of the first battery is lower than a preset first voltage during the operation by the power supply from the first battery. The switching means switches the power supply from the first battery to the power supply from the second battery when it is detected that the voltage of the first battery is lower than the first voltage. The first processing means performs a shutdown process after switching to the power supply from the second battery.SELECTED DRAWING: Figure 2
