Lenovo Thinkpad E15 gen2 GE4B0/GE5B0 NM-D011

[Maxpower3]

Thanks Maxpower3, I think I more or less understood, correct me if I'm wrong but I think it all comes from having a specific password stored in the EC chip and the ideal would be to be able to read that EC chip, like the other problem I have that I have not yet been able to solve with my other computer and that I have in another post (thinkpad yoga 11e) that saves the password in the nuvoton ncpe288 EC chip, since I have tried all possible ways without success and I think that until I can read that nuvoton EC chip I will not have a solution.

Why don't you restore your original BIOS from the post ?

The power issue isn't coming from there.
Do you know the password and did it work before?

With the image/dump that hoaca388 offered me, it worked, but it asked me for the supervisor password (I finally found the one I had set on the computer, but I set it and it didn't work; I mean, it was like another password and the one I set on the computer didn't work), so I restored my original dump/image and set the password I had set on the computer and it worked (that's why I had asked later here on the forum why hoaca388's dump/image didn't work with my password set on the computer, but you're still explaining it to me and I still need more knowledge to fully understand it). And the power problem, I'm sure it's because the MOSFETs are falling off the board, I still have to check that, but I was still unsure about the BIOS, since the password I set in the hoacca388 flashed image didn't work with the password I set myself...(in this case, I'm talking about the Lenovo ThinkPad E15, not the Yoga 11e), with the Yoga 11e, I haven't been able to unlock the BIOS password in any way.
