Embedded controller firmware for the Lenovo ThinkPad E460 built on the LCFC board NM-A551, targeting the ITE IT8586 EC chip. The small 50.2 KB rar archive holds only the EC code, not the main system BIOS. A corrupted EC image typically causes no power, no charging, or keyboard and fan faults, and reflashing the IT8586 with a suitable programmer often restores normal behaviour. NM-A551 follows the LCFC numbering used on Lenovo boards, so check the PCB marking and back up the existing EC contents before writing anything.
