Lenovo ThinkPad L14 NM-C631 is a laptop motherboard designed by LCFC and used in the Lenovo ThinkPad L14.

The catalog has 2 schematics, 1 boardview file and 3 BIOS files for it, posted between 2022 and 2024 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 0.1 and Rev 1.0). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .BDV format. OpenBoardView (free) usually opens these files; FlexBV works too. See OpenBoardView: Installation and First Steps.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

BIOS notes: some archives also hold EC/KBC firmware; versions with a cleaned ME region are included. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Also listed under platform GL5A0.

Frequently asked questions

Which laptops use the NM-C631 motherboard?
File names in the catalog tie NM-C631 to the Lenovo ThinkPad L14. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-C631 do I have?
Files for this board mention Rev 0.1 and Rev 1.0. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the NM-C631 boardview file?
The boardview for NM-C631 is available as .BDV. .BDV usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the NM-C631 BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
