          Describe the password screen, either:
          PC+LOCK (Power-On password)
          FACE+LOCK (Supervisor password)
          CYLINDER(number)+LOCK (Hard-drive password)

                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
                Attached the dump of the EEPROM ( i received the CH341A today)

                Could you help me to remove the supervisor password ?

                                          Somewhere in this topic are some instruction for unlock... I think you didn't read it.
                                          after pressing F1 key you will see the user password prompt.
                                          type 1234
                                          fallow the instruction on screen, send the hardware ID

                                          keep in mind that i'm with 2 hours earlier than you...
