Re: Remove_SMM... UEFI.
Originally posted by Daoud333 View PostHello 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
Could you help me to remove the supervisor password ?Last edited by SMDFlea; 04-01-2023, 07:27 AM.
