Lenovo IdeaPad 3 15IIL05 NM-D031 is a laptop motherboard designed by LCFC and used in the Lenovo IdeaPad 3 15IIL05 and Lenovo IdeaPad 3 14IIL05.

The catalog has 2 schematics, 4 boardview files and 8 BIOS files for it, posted between 2021 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 1.0; other revisions of the same board can differ in parts and layout.

The boardview comes in .BDV and .TVW format. .TVW files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. 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: file names mention 16 MB chip sizes. 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 GV550.

Files for this board mention 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-D031 boardview file?
The boardview for NM-D031 is available as .BDV and .TVW. .BDV usually opens in OpenBoardView (free) or FlexBV. .TVW usually needs FlexBV or the matching viewer. See What Is a Boardview File and Why You Need One.
What should I check before flashing the NM-D031 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 16 MB images; the dump size must match your chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
