An automated transaction machine can include a user-interface device, a computing device, a battery, a head portion, a first socket-half, a first electrical rail, and a relay. The a user-interface device can be configured to receive an input from a user and transmit the input. The computing device can receive the input. The battery can selectively direct electric power to the user-interface device and the computing device, which can all be housed in the head portion. The first socket-half can be exposed on an outside surface of the head portion and direct power to the user-interface device, the computing device, and the battery. The relay can be arranged to connect the battery and the first electrical rail in a first configuration and be switched between the first configuration and the second configuration by an output signal of the first socket-half.
