Schematic for the Compal LA-9641P motherboard, revision 1.0, supplied as a PDF inside a RAR archive of about 1.28 MB. The name does not state which laptop model uses the board, so identify it by the LA-9641P code silkscreened on the PCB. The LA-xxxxP pattern is Compal's own board numbering, and the sheets let a technician follow power rails, trace signals between chips, read component values and locate test points while hunting a short or a missing voltage. Open it with any PDF viewer after extracting, and confirm the revision on the board matches 1.0.
