If you are ready to proceed, head to and search for the repository named lenovo_bios_unlock . Read the 500-page issue thread for your specific model. Remember: With great power comes great amperage. Unlock wisely.

The "Lenovo BIOS Unlock Tool" is not a single download. It is a suite of techniques: UEFIPatch , RU.EFI , CH341A , and community patch scripts.
