Lenovo ThinkPad T420S is a laptop motherboard used in the Lenovo ThinkPad T420S.

The catalog has 4 schematics, 1 boardview file and 1 BIOS file for it, posted between 2017 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

The boardview comes in .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.

Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.
