An electrically conductive hinge provides for the transmission of electrical power and signals between a pivotally connected display unit and system unit of a portable computer and eliminates cable connections between the display unit and the system unit. Either the system unit, the display unit, or both units have a set of wipers which contact the conductive lines in the electrical track. The conductive lines are long enough to allow the display unit to be pivoted to and from its open and shut positions while the wipers remain in contact therewith. In one arrangement, the electrical track is manufactured on the hinge pin. In another arrangement, the electrical track is manufactured on a disk positioned at or near one end of the hinge pin.
