Ouchhh...yes better to buy a second hand then. If Aliexpress, avoid Akemy, cheap but definitely not trustable.

As lessons have to be learned, better previosuly ask for the card to be checked for a bios without password and computrace not activated

KYD motherboard Store​ was the most reponsive on this....

Before investigating that way, can you boot on usb?

if not, just leave your computer without any power source and remove the bios battery for some hours , also push the bios reset button on the mb (if there is one, but this is not a tamper one related to hardware intrusion ) for 20-30 seconds, and the power button too if you did not take the mb out.

I did this (one day without power) then i just reconnected the power supply and i had it solved. Then i could reset the bios to default setup and i mounted back everything with a new ssd (bc i discovered i had computrace activated...

After a few more days of searching, sanity-saving breaks included, and a whole lot of “what the heck is happening,” the issue just... vanished.

Yesss, really like, [I]poof[/I], gone. I can't explain it.

Maybe it was because the battery had been disconnected for ages, or maybe—just maybe—the blue moon teamed up with my trusty chunk of tourmaline to work some energetic protection magic?!

Long story short, the motherboard suddenly sprang back to life, and I could finally boot the OS normally.

No rhyme, no reason—just pure, unexplainable...

I think you should try CLEAR ME , i had the same as you on a T450, i cleared the management engine, reloaded my original bios once done and I could acces it again (without pswd as it was already autopatched)
