Compal LA-2921P board schematics at revision R4.0, in a 1.31 MB RAR archive. R4.0 points to a heavily revised, late version of the design. The name gives the Compal board code but no laptop brand or model, and the related LA-2922P differs by one digit. Compal is an ODM producing boards for various notebook vendors. Use the drawings to trace rails, locate test points and diagnose power faults. Check that the PCB shows LA-2921P and revision 4.0, since earlier revisions can differ.
