      Need some help with t490/t490s

      Just wondering what's the best method for removing bios passwords on them we get 100s off them but since you can't do the driver bypass. Need most consistent method.

              Rewrite EC dump to board. This will erase EC eeprom. You need to set serial number etc with service tool from Lenovo

                          Try to program back your backup file and see if the device works or not.

                              I think the patched method will not work with your device, maybe you need to use a proper programmer to program the SIO chip.

                                            Hey guys,

                                            have a laptop here that has a supervisor Password (dump in Attachements).
                                            Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
                                            the laptop works but everytime it wants me to type a supervisor password i never set.
                                            I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
                                            Anyway i wanted to ask what of the two chips is the ec bios because on the left...

                                            Help needed in unlocking BIOS Supervisor password - Lenovo X1 Yoga 5th Gen
                                            by baaligoga
                                            Good day, everyone!

                                            I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.

                                            I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...

                                            Lenovo P16 Gen1 Supervisor Password from factory
                                            by Pusher
                                            Hi, I bought a Lenovo P16 Gen1 from a private seller. The box was still originally sealed but when I want to enter the BIOS a supervisor password is required. Is it possible that the notebook was delivered by Lenovo with a password? What can I do to reset the password? Unfortunately, I no longer have contact with the seller.

                                            Supervisor password retrieval from Lenovo T550
                                            by Pascos
                                            Hi all,

                                            I bought a few Lenovo laptops from a batch, most of them having a 10th/11th gen Intel CPU, and I found out they all have a supervisor password enabled. I understand you would need soldering or a programmer to disable the supervisor password on these newer units, which I would like to prevent if at all possible. I have the suspicion that all the laptops are using the same password, though.

                                            In the batch there is also an earlier T550. Is there a method available to retrieve the supervisor password from this model so it can be tested with the others?
