PDF schematic for the Compal LA-D803P motherboard, project BAL22, stored in a 3.79 MB RAR. Compal names its boards in the LA-xxxxP format, and the BAL22 project label usually appears on the schematic title blocks. A technician uses the diagram to follow voltage rails from the charger to the CPU VRM, read the power-good chain and identify components on a shorted line. Pair it with a boardview for physical locations, and check that the LA number and revision on the PCB match.
