Embedded controller firmware for the ASUS X555LD, targeting the ITE IT8585 chip named in the file. At 29.9 KB it holds only the EC code, not the main BIOS. Technicians reflash the EC when a board shows no power-on, battery charging problems or keyboard failures linked to corrupted controller firmware. Writing an ITE controller usually needs a suitable EC programmer. Check the chip marking on the PCB matches the IT8585, and save the original EC contents before programming.
