Compal LA-A551P motherboard schematic at revision R1.0, compressed into a 969 KB RAR file. No brand, CPU, or graphics variant is stated in the name. Compal produces LA-numbered boards as an ODM for several laptop vendors, so one board may appear in differently branded machines. Use the drawing to follow power rails from the adapter input onward, locate test points, and identify which parts sit on a shorted net. Check the board number and revision printed on the PCB before relying on it.
