A portable information handling system keyboard cable integrates keyboard and point stick conductors in a common membrane to communicate user inputs from a keyboard and point stick to processing components. The cable terminates at a motherboard end with a ZIF connector to connect with processing components at the motherboard and terminates at keyboard end with a connector for keyboard and point stick conductors. In one embodiment, the keyboard and point stick conductors terminate in a common connector having conductive pads arranged in a V shape to connect with conductors extending from a keyboard membrane. In alternative embodiments, the point stick conductors extend out from the common membrane to align with point stick conductors extending from a keyboard assembly.
