Embedded controller firmware image for a Lenovo laptop built on the LCFC NM-E231 motherboard, named after the ITE IT8176FN-56A keyboard and power-management controller. The 56 KB binary holds the EC code that handles power sequencing, battery charging, fan control and keyboard scanning. NM-E231 follows the LCFC numbering pattern, the ODM that designs many Lenovo boards. Read and save the existing EC contents before writing, confirm the controller marking on the board, and expect a corrupted EC to cause no-power or charging faults.
