EC image of 4 MB for the Dell Latitude E7440 on Compal board LA-9591P, the second flash alongside the 8 MB main BIOS. The embedded controller region governs power-on, charging and keyboard functions, so damage here often shows as no power or charge faults. Confirm the LA-9591P code on the PCB and identify which chip holds the EC data. Back up the existing chip, write this image with an SPI programmer, and flash the main image to its own chip.
