About this board

This thread is for the ThinkPad T14s X13 GT4A5/GX3A5 with main board NM-C791.

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)
Boardview (.brd / .bdv / .cad)

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-C791 in File Finder.
