Need Bios For IdeaPad 3 15IAU7

[peste]

I'm confused. What's the importance of DMI. Do I have to put some thing in that area?

in that interval there is DMI information (S/N, TYPE, name, model, etc.), the bios on the site is virgin (empty in that interval), you have to take the information from your bios and put it in the virgin bios, use the HxD program, enter both bios into it, check that interval in both bios and (copy-paste) from yours into the virgin one... that's it..

Yeah, it didn't work. Either my old DMI is corrupt, or something else is wrong with my laptop. Any suggestions?

In these Reddit posts, I explained my issue and was convinced to re-flash my bios:
