Firmware for the Lenovo B460 class machine named BE460 in the file, built on the LCFC NM-A551 motherboard; no revision is given. NM-A numbering is the LCFC scheme used on Lenovo consumer laptops. The 4.05 MB RAR holds the BIOS image for the SPI flash. Technicians write such dumps with an external programmer to fix no-boot faults after corrupted updates. Since the model token is unusual, confirm the board number on the PCB, read and save the existing chip first, and compare sizes.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
