Archive for the Compal board LA-A999P, a 12.3 MB zip whose name gives only the board number. The LA-xxxxP format is Compal's ODM numbering, and such boards appear in laptops from Dell, Lenovo, HP, Acer and others, so the brand cannot be inferred from the name alone. Given the size, the package likely bundles a schematic PDF and possibly a boardview; inspect it after unpacking. Check that the LA-A999P code and revision printed on the PCB match before using it to trace rails, signals and test points.
