Keyboard controller firmware for a Lenovo notebook using the LCFC NM-A281 board, supplied as a small 33 KB RAR archive. The name specifies the ITE IT8586E as the KBC/EC chip, the part that handles power sequencing, battery charging and keyboard scanning. A corrupt EC image often leaves a board dead or unable to charge, so reflashing it is a common fix. Verify the NM-A281 marking and the EC part number on the PCB, and keep a backup of the existing contents before writing anything.
