Compal LA-F381P laptop motherboard schematic, supplied as a PDF packed inside a 4.37 MB RAR archive. The name gives no laptop brand or model, only the Compal board code, so confirm the LA-F381P marking on the PCB before using it. LA-xxxxP is the numbering Compal uses for its ODM boards built for several brands. Extract the archive and open the PDF in any viewer to trace power rails, follow signal paths between chips, read component values and find the reference designators involved in a short.
