PDF schematic for the Dell Inspiron 15-5000 series on Compal motherboard LA-B012P, revision r10, and noticeably larger at 3.06 MB than some other copies of the same board. Compal numbers its boards in the LA-xxxxP format, usually printed on the top side of the PCB. Use the drawings to locate the power circuits, follow rails from the adapter jack to the CPU regulators and find test points for measurement. Confirm the revision on the PCB first, since components can change between revisions.
