About this board
This thread is for the Lenovo A720 with main board DA0QU7MB8E0.
The board was manufactured by Quanta for Lenovo. Quanta board numbers start with DA and include MB, so you can confirm it on the PCB silkscreen. This listing is for revision 1.2; another revision of the same board can need a different file.
Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- 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.
If you have a working file for this board, please share it below. More files: search DA0QU7MB8E0 in File Finder.
