BIOS together with embedded controller firmware for the Lenovo ThinkPad E440 on LCFC motherboard NM-A161, delivered as a 4.81 MB RAR archive. The same board number is used on the E540, so make sure the dump matches your model. Having the EC image is useful when power-on, charging, battery or keyboard faults trace back to the controller firmware. Identify both chips on the board, read and save their original contents with a programmer, and verify each file size against its chip before writing.
