Wistron schematic for project EA40-HW with the ULV designation and board number 12243-1, delivered as a 3.97 MB PDF. The laptop brand is not stated in the name. Wistron uses five-digit project numbers with a dash suffix like this one, often on Dell and other brand notebooks. The pages let a technician trace power-on sequencing, measure expected rail voltages and identify components near a short. Make sure the 12243-1 marking on the PCB matches before taking values from it.
