ABSTRACT:
A method and apparatus are described for selectively activating a secondary power source, such as a backup battery, for an electronic device, such as dynamic RAM. A connector is described in conjunction with a circuit board including a first contact coupled to the backup battery, and a second contact coupled to the corresponding input for backup power associated with an electronic device. In this state, an open circuit is presented such that the battery is isolated from the electronic device. A socket is described for cooperating with the connector, which includes mating contacts corresponding to the first and second contacts previously described, and a shunt for establishing electrical continuity between these mating contacts. In this manner, a completed circuit is established between the battery and the electronic device when the socket is attached. A bypass connection is also described for maintaining connection between the battery and the electronic device independent of the socket, so that the circuit board may later be removed without threatening loss of accumulated memory contents.
