About this board
This thread is for the Lenovo U41-70 Laptop.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
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 Lenovo U41-70 Laptop in File Finder.
