Hi !

 

Welcome to Lenovo Community Forums.

 

We suggest that you rollback the BIOS version of the machine from the previous version and observe if the problem will persist.

 

You may download the older version of the BIOS from our support website and follow the steps below.

 

  • Go to the BIOS Setup menu (Read at Methods to enter BIOS)
  • Click on Security
  • Click on UEFI BIOS Update Option
  • Click on Secure Rollback Prevention
  • Click on Disable to Allow flashing to older version

 

Regards,
