Information handling system keyboard support with rail guide structure assembly to a housing rail

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 a first portion with key press detection sensors contiguous to a second portion with a touch detection sensor that supports a touchpad. In one embodiment, the membrane integrates a printed circuit board that couples a key matrix controller and a touch detection controller interfaced with a communications hub, such as a USB hub, to communicate key and touchpad inputs to a motherboard through a flexible connector portion of the membrane.

Dependencies are inferred from the claim text.
