Abstract:
An electronic device powered by a primary power source includes a switch, a first detection unit, a second detection unit, a warning unit and a secondary power source. The switch is configured for connecting and disconnecting the primary power source and the electronic device. The first detection unit is configured for detecting whether the switch is activated. The second detection unit is configured for detecting whether the primary power source is available if the switch is activated. The warning unit is configured for activating an alarm if the primary power source is unavailable. The secondary power source is configured for supplying electrical power to the first detection unit, the second detection unit and the warning unit.
