EC firmware for the Dell Inspiron 15R 5537 on Compal board LA-9981P, made for the ENE KB9012 keyboard controller, revision A4 as named. At 55.7 KB the archive holds the small controller image rather than a full BIOS. A corrupted KB9012 typically causes no power, charging or keyboard faults, and it is reprogrammed through its flashing interface with a suitable adapter. Compal uses the LA-xxxxP scheme; check that number on the PCB and read the existing EC contents before writing.
