About this board

Thinkpad L14 HL4A0/HL5A0 — motherboard NM-D271.

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-D271 in File Finder.

I tried flashing this bios but the laptop doesn't turn on.

My original bios file is working but it always crashes the OS, i tried replacing SSD, RAM but nothing worked.
I think its bios problem.

Can you please look into it?
