Abstract
A touchpad and palm rest base chassis assembly for an information handling system may comprise a base chassis for enclosing the information handling system including a keyboard opening, and a plurality of palm rest support surfaces, and a composite substrate of woven glass fiber impregnated with polycarbonate material forming a touchpad surface, through which haptic feedback may be provided and touch may be sensed by capacitive sensors including a printed circuit board assembly (PCBA) operatively connected to the composite substrate having a light emitting diode (LED) disposed within an etched opening on the underside of the composite substrate formed to guide LED light into the light transmissive composite substrate of the touchpad surface to illuminate an icon opening within an inked surface of the composite substrate to negate need of a separate light guide layer, and the touchpad and palm rest base chassis assembly affixed to the base chassis.
