EC firmware for the Lenovo E555 laptop, board NM-A241, in a ZIP archive of about 2.9 MB. NM-xxxx numbers follow the LCFC pattern, the Lenovo-owned design and manufacturing company. An embedded controller image is reflashed when the keyboard controller corrupts, causing no power, charging faults or fan problems. Write it with an SPI programmer such as a CH341A, and back up the original chip contents first. Check that the image size matches the flash chip capacity, because an image that does not match will not fit.
