PDF schematic for the Compal JAL20 mainboard, board number LA-4041P, revision 1.0 with the A00 marking, packed in a 1017 KB RAR archive. Compal uses the LA-xxxxP numbering for notebooks it builds for various brands. The schematic lets a technician follow power rails, check the power sequence, trace signals between chips and identify components around a short or a missing voltage. Any PDF reader opens it. Verify the revision printed on the board, as component values can change between revisions.
