About this board
This thread is for the ES430 ES530 with main board NM-B631.
LCFC (Lenovo/Compal) board numbers start with NM-. Check the number printed on the PCB before you download.
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.
If you have a working file for this board, please share it below. More files: search NM-B631 in File Finder.
