About this board

Thinkpad L14 GEN 2 AMD RYZEN — motherboard NM-D391.

Lenovo had this board built by LCFC; LCFC (Lenovo/Compal) board numbers start with NM-. Check the number printed on the PCB before you download.

From the title: AMD platform.

What this thread covers
  • BIOS (full SPI chip dump, .bin)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.

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-D391 in File Finder.
