I have two t470s laptops. After auto-patch they both do the same: the keyboard lights up and goes out, the power button lights up, after about 30 seconds a strange melody is heard, no display - and that's it.
I have successfully removed the password on several of T470s's before, but now I am doing it on another computer - maybe different hardware is the reason why it doesn't work anymore. But I don't know what has changed exactly. From software - only Python version, every other thing is the same.
Both machines are 20JT-SOSM1G (motherboards WIN LIPC PCL10N07803). Numbers: PC-OUFQCT...
