Schematic in PDF for Compal board LA-D581P, revision 1.0 by the R10 tag, in a 3.06 MB RAR. The name itself gives no laptop model, though this board number appears elsewhere in the index with Alienware 13 R3 files. The circuit diagram lets a technician trace power rails, check MOSFET and regulator circuits, follow enable and power-good signals and identify parts near a short. Compal's LA prefix marks main boards. Confirm that the PCB number and revision match before relying on the values.
