EC firmware for the ASUS K550J, written for the ITE IT8585E embedded controller and marked as working. The small 30.4 KB archive fits a keyboard controller image rather than a full BIOS. A faulty EC code can cause no power, dead keyboard or charging faults, and reflashing the controller can resolve them. Writing an ITE EC usually requires a dedicated programmer or tool, so confirm the chip marking on the board matches, and read out the existing firmware before overwriting it.
