Lenovo Yoga 11S NM-A191 is a laptop motherboard designed by LCFC and used in the Lenovo Yoga 11S.

The catalog has 1 schematic, 2 boardview files and 1 BIOS file for it, posted in 2022 across 3 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 .TVW 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.

Frequently asked questions

Which laptops use the NM-A191 motherboard?
File names in the catalog tie NM-A191 to the Lenovo Yoga 11S. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-A191 do I have?
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-A191 boardview file?
The boardview for NM-A191 is available as .TVW. .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-A191 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.
