    Lenovo X1 Yoga 1st Gen (model - 20FQ) with a locked BIOS

    Hey all, I have a Lenovo X1 Yoga 1st Gen (model - 20FQ) with a locked BIOS. I would like to unlock it.

    Currently I have it apart in all its glorious bits looking for the security eeprom that I can't find. Plan was to jump it. Next step I think is to pull the BIOS IC and flash a decryption file to it?? I'm a bit confused on that process.

    1. Pull the BIOS IC,
    2. Read and save the original locked file
    3. Flash the decryption file
    4. Install and boot up and remove password from BIOS
    5. Remove BIOS IC again
    6. Flash Original locked BIOS back
    7. Install and jump for joy??

    Can someone let me know if I'm on the right track.

    Also is there a known decryption BIOS for the X1 Yoga 1st Gen

      Re: ThinkPad X1 Yoga 1st Gen (Type 20FR) BIOS needed

      Okay I believe I need to dump my locked file and attach it here and you fine people will mod it for me? Don't want to pull it till I have a solid plan.

      Oh, I probably should have mentioned that when it was together, I could still get into Windows, the whole thing isn't locked, just the bios.

                  Hi, friends!
                  I need help with my Yoga 1st Gen (20FB000QUS). I upgraded the MoBo to have 16GB, so I bought the same MoBo (14282-2M LRV1 MB 448.04P15.002M) on Aliexpress, but with the X1 Carbon 4th Gen (20FBA05ECD). I managed to edit the BIOS with the Intel ME/TXE injector tool and clean the ME and add the correct Chipset codes, but the Stylus Active Pen is not charging power. I measured the voltage on the original Yoga MoBo and it is 3.341volts/3.351volts, but on the X1 Carbon MoBo it is only 0.5volts, not enough to charge the Stylus Active Pen. This is definitely some missing ACPI code in the BIOS that releases the voltage to charge the pen, but unfortunately I don't know how to solve this problem. If anyone can help me, I would really appreciate it!

                      by Loki_Fido
                      Hi everyone, hope everyone's having a great day.

                      I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
                      I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

                      So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
                      Does this mean the BIOS is fine? making it a hardware issue?

                      I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...

                      Lenovo Yoga Slim 7 14APU8 Bios Request
                      by beogeek
                      I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

                      Attached is the bios dump in the state I received it...

                      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...
