HP CQ42 DA0AX2MB6E1 is a laptop motherboard designed by Quanta and used in the HP CQ42, HP Presario CQ62, HP G42 and HP Presario CQ56 and 3 more.

The catalog has 4 schematics, 1 boardview file and 19 BIOS files for it, posted between 2017 and 2024 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 4 board revisions (Rev 1A, Rev A, Rev E and Rev F). 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 2 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 AX2; codes DA0AX2MB6E0, DA0AX2MB6F0, Quanta AX2.
