Windows UEFI Firmware Update (V2222) corrupted BIOS Supervisor Password - Lecoo N176A

think now 0

Summary: After a mandatory Windows Update (LecooN176A - Firmware), my laptop's BIOS Supervisor Password logic was corrupted. Despite knowing the correct password, the system rejects it as incorrect, while the User Password remains functional.

Lenovo Bellator Fighter 7000, 8940hx, RTX 5060 laptops.

BIOS error, causing a Supervisor BIOS password error even when entered correctly. The user BIOS password works normally.
I don't know how to contact the manufacturer because warranty support isn't available in my country.

The Lenovo/Lecoo website only provides BIOS version v2020, but somehow Windows 11 found version v2222 and installed it on my machine, causing the error.

Does anyone have any information or assistance? Thank you very much!

Hi think now,

Can you boot into Windows now?

If you can boot into Windows, you can re-flash the old version by official manufactural tool.

If you cannot, you need to bring your laptop to a repair shop. They will take out the BIOS chip, flash the BIOS then put it back to your computer. This is not a complex progress.

If you have any updates, please feel free to let me know.

hi,

I can log into Windows. I can use Windows normally. But I can't change the settings in the BIOS because the Super BIOS password is incorrect even though I enter it correctly.

My current BIOS is v2222. Is reinstalling BIOS v2020 dangerous? Will it cause the BIOS to freeze?

Where can Microsoft obtain the v2222 BIOS? Can they provide version v2222 or higher for installation?

The latest BIOS version v2020 from the manufacturer link: https://iknow.lenovo.com.cn/detail/429447

Thank you!

Hi think now,

It seems this is the problem of v2222 BIOS version. Please consider these suggestions:

Reset current BIOS.

Downgrade to v2020. You might need to enable the rollback option in BIOS settings.

Report the problem to Lenovo/Lecoo and wait for the next BIOS that fix the problem.

I hope that above information is helpful to you.

Microsoft, could you please provide me with the v2222 installation file? I can't find the v2222 installation file on the Lenovo website. Installing v2222 will overwrite and delete the old BIOS password.

I've contacted Lenovo, but they refuse to resolve the issue, claiming they don't have v2222. I don't understand where Microsoft got v2222 from?

Thanks!

Hi think now,

I really wish I could provide you v2222. However, it is tied to back‑end systems and service functionality, and unfortunately, we don't have the authority or access to do that.

This is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas.

Thank you for your understanding.
