Compal LA-3081P motherboard schematics at revision R0.2, archived as a 1.08 MB RAR. The LA-xxxxP format is Compal's own board-numbering scheme, and such boards end up in laptops sold by many brands, so the printed PCB code is the reliable identifier. Technicians use these sheets to trace the power sequence, measure expected voltages at test points and work out which part sits behind a shorted rail. R0.2 is an early engineering revision, so small differences from your board are possible and the silkscreened revision should be checked first.
