Abstract: An electronic apparatus includes a power source, a power monitoring unit configured to monitor an output voltage output from the power source, an acceptance unit configured to accept a user operation to turn off the electronic apparatus, and an execution unit configured to operate using power output from the power source, execute shutdown processing in response to the user operation accepted through the acceptance unit, and execute the shutdown processing when the output voltage monitored by the power monitoring unit is lower than a threshold voltage. The threshold voltage is higher than a guaranteed operation voltage of the execution unit.
