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

@fire1234
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
