Lenovo Yoga S940-14IIL 18777-1 is a laptop motherboard designed by Wistron and used in the Lenovo Yoga S940-14IIL.

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

The boardview comes in .BDV and .CAD format. .CAD 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.

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 Wistron LS40; codes 448.0HB02.
