Dell Latitude E5440 firmware set containing both the BIOS and EC images, for the Compal LA-9832P main board, packed as a 6.5 MB RAR archive. Compal is the ODM behind this board, using its LA-xxxxP numbering. The EC firmware controls power-on, keyboard and battery charging, so flashing it can fix dead or non-charging boards. Write each image to its own chip with a programmer after backing up the originals, and check the LA number on the PCB before use.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopbios21. Enginerys does not host this file.
