Abstract
A portable information handling system is assembled and disassembled by a keystone assembly that couples at an upper surface of the portable housing to overlap a keyboard assembly that covers processing components disposed in the portable housing. The keyboard assembly includes a membrane having plural input sensors and a capacitive touch sensor that interface with a communications hub, such as a USB communications hub coupled to the membrane, that communicates both the keyboard inputs and touchpad inputs to a motherboard through first and second contacts that support a differential serial pair.
