HP ProBook 440 G3 DAX61CMB6C0 is a laptop motherboard designed by Quanta and used in the HP ProBook 440 G3, HP ProBook 430, HP 43 G3 and HP ProBook 430 G3.

The catalog has 2 schematics, 2 boardview files and 15 BIOS files for it, posted between 2019 and 2025 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 1A, Rev C and Rev D). 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 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 16 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 platform Quanta X61C; codes DAX61CMB6D0.
