Dell Inspiron 3647 13040-1M is a laptop motherboard designed by Wistron and used in the Dell Inspiron 3647, Dell OptiPlex 3020 MIH81R, Dell Vostro MIH81R and Dell 3800 MIH81R and 2 more.

The catalog has 2 schematics, 1 boardview file and 8 BIOS files for it, posted between 2021 and 2025 across 4 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.

BIOS notes: file names mention 8 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 codes 13040-1.
