    Lenovo Yoga370 password

    Hi all,

    got an Lenovo Yoga 370 with BiosPW - anyway I can remove this? I saw a company providing kind of a "Master"-Bios where you have to provide a generated Code to unlock the bios in the final step.

    Dont know if there is another way around this. The dump is attached and checked 3x with diff (no errors). The eerprom is a W25Q128

    Any Help is realy appreciated

          Thank you for the quick response.
          Flash was succsefully but the following occures:
          - Bad CRC (ok, should be done after setting up time-date etc in bios)
          - It booted still with a Password, i entered admin1 as a Test, the following screen showed me Hardware ID: 2151605481 - i entered 1234 as key.
          - It resetted TPM stuff, rebooted. Stilll showing CRC-Error, and if I want to enter setup it only shows me "Entering Setup.." with the dots "..." progressing from 1Dot to 5Dots and nothing more.
          / Any hint for me? Should I had post the HardwareID here to get the correct key?
          / Should I reflash the posted bin again?

                      ok, I dont get to the point where I can enter the BiosPW nor the ID again, so I guess i f´ed this up - I reflashed original bios back, and it works - even if I entered the wrong stuff *facepalm* guess its my lucky day *nervous-laughter*
                      Ok - thank you CraterM for this quick reply and help.
                      Is there a way to extract the all.ro bios part to use it for other machines/models? If you want you can PM the answer if its not for the public eye ^^ anyway thank you so much again

                          Should I buy a Lenovo Thinkpad E495 with bios password?
                          by RMDUiFT
                          Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                          I have a few questions:
                          • If I would buy this laptop and have

                          For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

                          Lenovo Yoga X380 22LH Supervisor Password removal
                          by AppleLover123
                          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...

                          HOW TO: Tutorial for removing Lenovo x390 yoga bios password
                          by questore
                          Hi Guys,
                          I thought I write you a tutorial on how to remove your bios password from your lenovo x390 yoga.
                          Steps:
                          1. Get an EC programmer and read the EC firmware.
                          2. Back up your working EC file !!! (on this modell EC stores all hardware infos and you cannot replace it with others)
                          3. In your EC firmware file find all of these ranges with a hex editor and replace them with 00:
                          !!!!!! IMPORTANT THAT YOU ONLY MODIFIED THE SPECIFIED RANGES AND NO MORE.
                          (I have used HxD Hex editor FREE for this since I found that it is easy to replace ranges)
                          0x36000...
