Here is what I have already tried without success:
- Updated the official BIOS to the latest version.

- Searched for days for a solution, but tools like Uone are nowhere to be found, and the Lenovo Motherboard Self-Repair Tool is no longer available for download for my specific model.
Here are the exact details of my notebook taken directly from the back cover and the BIOS screen:
- Model Name: ThinkBook 14 G3 ACL
