Step-by-Step:

  • Back up the original BIOS. Open NeoProgrammer, detect chip (Winbond 25Q128), click “Read”. Save as t470_backup.bin.

  • Write the clean dump. Click “Erase”, then “Blank Check”, then “Write”, then “Verify”.
  • Reassemble and boot. Press F1 – no password prompt. Set a new password if desired.

    Warning: You’ll need to hex-edit the dump to remove the password hash. This is not beginner-friendly but 100% effective.

    If you do not want to solder or use a clip, three commercial tools are verified to work via the SMBus (System Management Bus) without disassembly:

    Recommendation: For a single laptop, the $10 CH341A kit is the verified best value. For a repair shop, buy the Vertyanov. Software:
