Compal schematic for board LA-D704P, delivered as a 2.36 MB PDF with no brand, model or revision in the name. LA-xxxxP is Compal numbering used on boards built for several laptop brands, so the PCB silkscreen is the best confirmation. The diagram allows tracing power rails from the adapter input onward, checking the power sequence and EC signals, and finding component values during short diagnosis. Open it in any PDF viewer and check the board revision on the PCB before relying on specific parts.
