EC firmware image for the Lenovo ThinkPad T14 Gen 3 on LCFC board NM-E441 revision 1.0, stored as a raw 16 MB BIN. The embedded controller handles power sequencing, battery charging, keyboard and fan control, so a damaged EC chip can cause no-power or no-charge faults. NM-xxxx codes come from LCFC, Lenovo's own ODM. Confirm the board code and revision printed on the PCB, read and keep the original EC flash before programming, and check the file matches the chip size.
