PDF schematic for the Dell Latitude E6440, project VAL90, Compal motherboard LA-9931P, 868 KB. The E6440 came on more than one Compal board, so make sure the PCB reads LA-9931P rather than a sibling design such as LA-9932P before using it. Compal's LA- numbering appears on many Dell business laptops. The schematic helps trace power rails, follow the power-on sequence, check signal names and part values, and narrow down a short to a specific circuit. Any PDF reader opens it.
