Embedded controller firmware for the ITE IT8585E chip on the ASUS X550LD, mainboard revision 2.0, compressed into a 30.2 KB RAR. The EC manages power sequencing, battery charging, fan control and keyboard scanning, so a corrupted image can leave the board dead or unable to charge. The file is small because it holds only the controller firmware, not the main BIOS. Confirm the board revision on the PCB, back up the original controller contents, and reprogram with a tool that supports this ITE device.
