Schematic for the Compal LA-9912P notebook motherboard, revision 1.0, delivered as a 6.94 MB PDF. Compal, an ODM producing laptops for numerous brands, uses the LA-xxxxP numbering, and the file name does not say which retail model carries this board. The drawings support tracing the charging circuit, voltage regulators, power sequencing signals and EC connections when diagnosing no-power or no-display faults. Verify the board number and revision silkscreened on the PCB match r1.0 before trusting component placement and values.
