The present invention discloses methods for protecting a peripheral device in a computing system from electrical surge currents, the method including the steps of: providing a controller operationally connected to a host system; and reversibly conductively connecting, via the controller, wires of the device to the host system. Preferably, the device is connected to the host system via a connector. Preferably, the device is hard-wired to the host system. Preferably, at least some wires of the device are isolated from the host system via a mechanical contactor. Preferably, at least some wires of the device are isolated from the host system via an optical isolator. Preferably, the method further includes the step of: charging a switching battery when the device is disconnected from the host system. Most preferably, the method further includes the step of: powering the device using the battery when the device is connected to the host system.
