Engineering revision R0.3 of the Compal LA-9861P motherboard schematic, stored in a RAR archive of 1.09 MB. The same board is also available at revisions 0.1 and 1.0, so choose the version matching the revision silkscreened on your PCB. The name does not identify the laptop brand, CPU or GPU. Extract it and use the diagrams to follow the power sequence from the adapter to the core regulators, locate test points and track down a shorted component, keeping in mind early drafts can differ.
