Toshiba Satellite C855D 6050A2509701 is a laptop motherboard designed by Inventec and used in the Toshiba Satellite C855D, Toshiba C850DC855D and Toshiba C855D-S5340.

The catalog has 2 schematics, 3 boardview files and 2 BIOS files for it, posted between 2021 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev A02 and Rev A03). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .BDV and .BRD 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 and 4 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.
