need remove password lenovo p52

[Boergelund]

Hi,
I've got the same Problem with my P52. When I flash the autopatched file i get this melody and the screen stays black. Maybe someone could help with my file?
I attached both the original and the patched file. After reflashing the original dump the system starts with a locked bios.

thanks in advance

Has anyone solved the password problem in bios with lenovo P52. Autopacher does not work, a melody is heard when the laptop is started with a patched bios and now picture on screen.

Thank you Peste for your effort and the quick reaction but unfortunately the new bios with autpatcher isn't working.

I read somewhere in the forum that the Macronix chip could be the problem.

I download bios REV1.0 but it takes 45 seconds to start up and the device works normally. I updated bios ver 1.54 to download from Lenovo website, the laptop does not display the image. It's confusing....
I hope you can help me fix the attached clearme file and try it out, thank you
