About this board
This thread is for the Thinkpad T470 T470P (Type 20HD 20HE) DT473 with main board NM-B071.
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.
What this thread covers
- BIOS (full SPI chip dump, .bin)
- Schematic (PDF)
Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.
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-B071 in File Finder.
