Schematic PDF for Dell motherboard LA-A101P, a Compal design, 3.35 MB in size, with no laptop model in the name. Compal numbers its notebook boards LA-xxxxP, so look for the same code on the PCB to confirm the match. The document is a reference for power rails, voltage regulator circuits, signal paths and connector pinouts, useful when tracing shorts or missing voltages. A boardview for the same number makes locating parts much easier.
