Schematics for the Compal LA-2861 notebook motherboard at revision R1.0, compressed into an 815 KB RAR file. The number follows Compal's LA-series coding without the P suffix, and the board can turn up in laptops sold under different brands, so check the silkscreen on the PCB. Extract the PDF to trace the power rails, follow the power-on sequence, read connector pinouts and find test points when chasing faults. Confirm that the board revision matches R1.0 before using component values from these pages.
