Compal LA-2831 notebook motherboard schematics, revision D, in a 1.35 MB RAR archive. The letter revision is unusual next to the R0.x style used on many Compal sheets, so compare it with the marking on your PCB before relying on part values. The LA code follows Compal's board numbering, used on laptops built for different brands. Once extracted, the PDF is useful for tracing power rails and control signals, locating test points and finding the component responsible for a short or a missing voltage.
