About this board

Files for the Thinkpad E14 Gen 7 motherboard, board number NM-G631.

The board was manufactured by LCFC for Lenovo. LCFC (Lenovo/Compal) board numbers start with NM-, so you can confirm it on the PCB silkscreen.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search NM-G631 in File Finder.
