HP Presario CQ56 DAAX3MB16A1 is a laptop motherboard designed by Quanta and used in the HP Presario CQ56, HP Presario CQ62, HP Presario CQ62-2XXXX and HP Pavilion G56 and 3 more.

The catalog has 1 schematic, 1 boardview file and 10 BIOS files for it, posted between 2017 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev A). 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 is packed in an archive and the file name does not say which format is inside; most open in OpenBoardView or FlexBV. What Is a Boardview File and Why You Need One lists the common formats.

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 1 MB and 4 MB chip sizes; some archives also hold EC/KBC firmware. 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 AX3; codes DAAX3MB16A0.
