Schematic diagram for the Compal LA-A972P board, a 1.19 MB PDF that appears to be a second copy of the same document given the numbered suffix. Brand, model and revision are not part of the name. The LA-xxxxP code is Compal's notebook board pattern, printed on the PCB, and it is the dependable way to match. Open it in a PDF viewer to follow power paths, read signal names between chips and find part references for measurement. Confirm the revision on your board before trusting component values.
