Compal LA-4851P service schematic at revision R1.0, supplied as a RAR archive of about 1.03 MB. Revision 1.0 is typically the production release of a Compal design, so it should match most retail boards that carry this code. LA numbers belong to Compal's own scheme and do not name the brand the laptop was sold under. Use the schematic to trace power rails, check MOSFET and regulator circuits, follow the power-on sequence and locate the parts behind a short. Open the extracted PDF in any document viewer.
