Lenovo IdeaPad 330 NM-B661 is a laptop motherboard designed by LCFC and used in the Lenovo IdeaPad 330, Lenovo IdeaPad 330-14IGM and Lenovo IdeaPad 330-15IGM.

The catalog has 3 schematics, 4 boardview files and 12 BIOS files for it, posted between 2019 and 2025 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 .TVW and .BDV format. .TVW files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. See How to Open .TVW Boardview Files.

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.

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 FG5N2.

Which laptops use the NM-B661 motherboard?
File names in the catalog tie NM-B661 to the Lenovo IdeaPad 330, Lenovo IdeaPad 330-14IGM and Lenovo IdeaPad 330-15IGM. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-B661 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-B661 boardview file?
The boardview for NM-B661 is available as .TVW and .BDV. .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-B661 BIOS?
Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
