X455LD Rev 2.1 KB9018 ECROM

BIOS .bin 128 KB Shared

Embedded controller firmware for the ASUS X455LD, board revision 2.1, intended for the ENE KB9018 EC named in the file name. The 128 KB image controls power-on sequencing, battery charging, fan and keyboard functions, so a damaged copy often leaves the laptop without power or charge. Depending on the board layout it is written either into the EC directly or into a separate small flash chip. Confirm the revision on the PCB and keep a backup of the existing EC contents before programming.
