HP ProBook 440 G4 DA0X81MB6E0 is a laptop motherboard designed by Quanta and used in the HP ProBook 440 G4, HP ProBook 430 G4, HP ProBook 440 and HP ProBook 440-G4.

The catalog has 6 schematics, 5 boardview files, 24 BIOS files and 1 archive for it, posted between 2018 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev A and Rev E). 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 .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: versions with a cleaned ME region are included. 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 X81; codes DA0X81MB6EO, DA0X8BMB6F0, DA0X8CMB6E0.

Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the DA0X81MB6E0 boardview file?
The boardview for DA0X81MB6E0 is available as .BRD and .BDV. .BRD and .BDV usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
