About this board
This thread is for the HP pavilion 15-n257sr with main board DA0U81MB6C0.
The board was manufactured by Quanta for HP. Quanta board numbers start with DA and include MB, so you can confirm it on the PCB silkscreen. Board revision: C. Match the revision as well as the board number.
What this thread covers
- BIOS (full SPI chip dump, .bin)
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
