BIOS and EC firmware for the Dell Latitude E6440, project VAL90, Compal board LA-9931P revision 1.0, delivered as a 6.70 MB RAR archive. LA-xxxxP numbering is the Compal pattern, the ODM that produced this Dell mainboard. Including the embedded controller image helps when power-on or charging faults stem from corrupted keyboard controller firmware. Flash each image to its own chip with a programmer, backing up the originals first, and confirm the PCB revision and chip sizes match before writing.
