Schematic diagrams for the Compal LA-9641P mainboard, revision R1.0, shipped as a 1.23 MB RAR archive. The file name gives no laptop brand or model, only the Compal board code, which this ODM uses on boards made for many vendors. Use it to follow voltage rails, locate power-good and enable signals, and see which capacitors and regulators feed a short. Unpack it to reach the PDF. A separate R0.3 revision of this board exists, so match the revision on the PCB before comparing values.
