    Getting rid of supervisor for x1 carbon 8th gen

    Click image for larger version  Name:	20250621_105925.jpg Views:	0 Size:	218.8 KB ID:	3726527Hi there,
    As title says, i need to get rid of supervisor password, at bios enter if i let blank, it goes into bios but limited settings can be aplied.
    X1 Carbon gen 8th : 20U9 - 0084MH
    I opened and i think i found the bios chip somewhere near ssd m2.
    Now i have some electronic skills and i have CH341A programmer with an additional 1.8v converter for those chips, but i am not sure if this chip is 1.8v or 3.3v.
    I have read some topics and i saw there is a method to short some pins to get rid of that supervisor password, but i could not find relevant method for x1 carbon 8th gen.
    Can you lead me? How to do it properly?

        The password is stored in the EC. See here for a description how to delete it: https://www.badcaps.net/forum/troubl...ssword-removal

          🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
          by macabook
          Hello everyone,

          I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
          🧩 Initial Issue
          • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
          • External display (HDMI) shows
          ...

          Lenovo Thinkpad X1 carbon 11th Gen BIOS problem
          by MaxonDomkrat
          Hi everyone.

          I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...

          Thinkpad P14s Gen 4, BIOS Supervisor Password
          by badzymandiaz
          I have a laptop that was purchased second-hand, and I am able to boot Windows on and extract the BIOS dump (ONLY the BIOS region, I was unable to dump anything else due to an FCERR I received trying to dump the other regions) and use normally. However, because the BIOS is locked with a supervisor password, I am unable to use anything else except for Windows, and it has also disabled some hardware features of the laptop itself, such as the fingerprinting module, etc. that I really do wish to use.

          I have been digging around for nearly 2 weeks trying to find any mention of the same model...

          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...
