Abstract
A notebook computer or other electronic device has a flexible cable interconnecting electronic circuitry in a base with electronic circuitry in a cover. A flexible potentiometer is coupled to said flexible cable in a location which bends when said cover is opened and closed with respect to the base. The resistance of the flexible potentiometer has a first value when the cover is closed and has a second value when the cover is open. A detection circuit is responsive to the resistance of the flexible potentiometer and generates an output signal which indicates whether the cover is open or closed.
