A 2 MB EC firmware image for the Dell Latitude E5520, board 10ELT15F001-A, revision A01. It pairs with a separate SB system BIOS dump for the same board. The embedded controller handles power sequencing, battery charging and keyboard functions, so a corrupt EC chip often causes no power or no-start symptoms. A 2 MB size suits a 16 Mbit SPI chip. Locate the right chip, back it up with a programmer, and verify the board revision before flashing.
