HP 20-C DAN91CMB6D0 is a laptop motherboard designed by Quanta and used in the HP 20-C.

The catalog has 4 schematics, 1 boardview file and 5 BIOS files for it, posted between 2021 and 2024 across 3 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev D; 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.

BIOS notes: file names mention 8 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 N91C; codes Quanta N91C.
