      I look over your dumbs. Both look buggy, are you sure your BIOS chips are read correctly ?

          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.

                                            Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.

                                            For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent...

                                            Is unlocking UEFI worth the hassle? (Surface Pro 4)
                                            by CronaxFD
                                            Hey guys,

                                            Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
                                            I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
                                            Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
                                            It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.

                                            Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?

                                            From what I've...

                                            Intel NUC NUC6i3SYH UEFI Update went wrong
                                            by S70rm7r00p3r
                                            Hi guys.

                                            I am very new to this business and i have some questions. Maybe someone can help me further.

                                            I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!

                                            ...

                                            I have a Fujitsu laptop AH562 witn a BIOS-UEFI problem since I converted the HDD to a SSD. For more details on the paltop go to the following link:

                                            After copying the HDD to SSD with ALtiris utility provided with the Kingston SSD and replacing the HDD with the SSD the laptop went into a startup loop with no screen display and only the disk LED flashing twice per second. I waited for approximatly 2h and then stopped the laptop...
