Compal LA-B012P schematic in PDF, with r10 in the name most likely pointing to revision 1.0. LA-xxxxP is Compal's ODM numbering, and no laptop brand is given, so match by the PCB silkscreen. Use the diagrams to trace voltage regulators, standby and main rails, reset and power button logic, and to identify parts around a short. Open it in a standard PDF reader, and confirm the revision in the title block matches your board.
