Compal LA-2871 motherboard schematics at revision R1.0, stored in a 915 KB RAR archive. The LA number follows Compal's board coding, even though the name leaves off the usual P suffix, and boards like this go into laptops sold under a range of brands. Once extracted, the diagrams show the power rails, regulator circuits, connector pinouts and signal paths, which helps when measuring test points or isolating a short. Confirm that the code and revision printed on your PCB agree with R1.0 before relying on the drawings.
