HP Pavilion DV4 package on Compal board LA-4101P with the Intel ICH9 southbridge, revision 03, in a 1.56 MB RAR. The LA-xxxxP pattern is Compal numbering, and the revision printed on the PCB should agree before comparing values. Technicians use such schematics in a PDF reader to follow power sequencing, check the always-on and main rails, trace signals to the ICH9 and locate components or test points when a board is dead or shorted.
