1. An information handling system comprising:
a housing having first and second housing portions rotationally coupled by a hinge;
a processor disposed in the first housing portion and operable to execute instructions that process information;
a memory disposed in the first housing portion and interfaced with the processor, the memory storing the instructions and information; and
a keyboard assembly having plural keys at an upper surface configured to accept end user key press inputs and having a membrane with first and second contiguous portions formed in a common membrane film, the first contiguous portion having key press detection sensors to detect the end user key press inputs when an end user presses a key to contact against the membrane, the second contiguous portion having a touch detection surface to detect touchpad touch inputs;
a printed circuit board integrated with the membrane;
a key matrix controller coupled to the printed circuit board to detect key touches at the key press detection sensors; and
a touch detection controller coupled to the printed circuit board to detect touchpad touch inputs;
a motherboard disposed in the housing and supporting communication between the processor and memory; and
a communication hub coupled to the printed circuit board and interfaced with the key matrix controller and the touch detection controller;
wherein the printed circuit board comprises a flexible printed circuit board having a connector interfaced with the communication hub and positioned to fold to align with a connector of the motherboard.
