Lenovo ThinkPad P1 18809-1 is a laptop motherboard designed by Wistron and used in the Lenovo ThinkPad P1.

The catalog has 1 schematic, 3 boardview files and 3 BIOS files for it, posted between 2023 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

The boardview comes in .BRD and .BDV format. OpenBoardView (free) usually opens these files; FlexBV works too. 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 2 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.
