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 plural liquid detection circuits exposed at a surface of the membrane to detect liquid spillage, such as exposed conductive pads that short in the presence of a liquid or resistive circuits that sense changes in resistance associated with contact with a liquid. A processing resource interfaced with the liquid detection circuits stores liquid detection events in non-transitory memory of the membrane, such as a controller and flash memory coupled to a printed circuit board formed in the membrane.
