BIOS and EC firmware package for the 2019 Lenovo Legion Y7000 on the NM-C371 motherboard. NM-xxxx numbers follow the LCFC scheme, Lenovo's own ODM. Having both the system BIOS and the embedded controller firmware matters, since a corrupted EC can cause no-power, charging or fan faults that a BIOS reflash alone will not fix. The 5.65 MB ZIP is meant for external programming of the respective chips. Match the board number on the PCB, back up both originals and verify each image size before writing.
