Compal LA-6884P schematics at revision R1.0, delivered in a 1.84 MB RAR archive. The LA-xxxxP pattern is Compal's main-board numbering, used on laptops manufactured for different brands, so the code printed on the PCB is what to match. Open the extracted PDF to follow charging, standby and CPU power rails, trace signals to the embedded controller and find test points while diagnosing no-power or short-circuit faults. R1.0 generally marks a production build, but check the board's printed revision before relying on the sheets.
