Problem solved after downgrading BIOS (enable downgrade from BIOS) with the initial firmware:

https://download.lenovo.com/consumer/mobiles/c2cn18ww.exe

It appears as Intel PTT. If it doesn't appear immediately press buttons reset default values or load default settings.

It appeared to me then.

Dear Lenovo,

 

This solution should have come rom yourselves directly. How come the BIOS update version  2.0 disables such a feature? There should be another update issued, which automatically fixes this issue.

 

Thank you!
