Schematic in PDF form for the Acer Aspire 5742 and 5791 notebooks, built on a Compal mainboard according to the name, although the exact LA board number is not given. Compal identifies its laptop boards with LA-xxxxP codes silkscreened on the PCB, so read that marking before relying on these pages. A technician uses the diagram to trace power rails, follow signals between the chipset and connectors, and locate the components involved in a short or no-power fault. Any PDF viewer opens it, and text search helps find net names quickly.
