Sony VAIO PCG-5KFP MBX-177 is a laptop motherboard designed by Quanta and used in the Sony VAIO PCG-5KFP, Sony GD1A, Sony PCG-5G2T and Sony VGN-CR13 and 2 more.

The catalog has 7 schematics, 3 boardview files and 5 BIOS files for it, posted between 2017 and 2022 across 3 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 1A; other revisions of the same board can differ in parts and layout.

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.

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 Quanta GD1.
