    The name of utility is "ThinkPad Maintenance Utilities V1.11" or newer version, look for UEFI version.

      just download the latest bios from the lenovo website and create a bootable usb with the bios image downloaded and you will have the option to either update bios or rewrite DMI info.

          Re: Remove_SMM... UEFI.

          Hello the team !

          i have a Lenovo Thinkpad T460 of a friend with startup password locked. No boot in windows.
          ( MB Lenovo NM-A581 REV 3.0 )

          Error messages :

          0271 : Check Date and Time settings

          ---> i have tried to remove CMOS Battery


          0183 : Bad CRC of Security Settings in EFI variable.

          ---> EEPROM seems to be corrupted

          Press F1 to enter Setup.

          ---> and then ask for startup password ( supervisor password is also configured)
          no access anymore to the UEFI Bios.



          It is possible to recover with dump EEPROM and then patch it ?
          ( it's an Winbond 25Q128FV )

          Thanks for your advices.

          Dave
