Schematic PDF for the Dell Latitude E7440, built on Compal board LA-9591P revision 0.4. It documents power sequencing, voltage regulators, the EC, the chipset and connector pinouts, letting a technician trace rails and signals while diagnosing faults. It pairs well with the matching boardview to locate parts physically. Any PDF reader opens it. Check the revision printed on the PCB, since component values and placements can change between Compal revisions of the same LA board.
