Problems HP 4540s BIOS - Crazy Power issues

HP Recommended
HP Probook 4540s
Microsoft Windows 10 (64-bit)

Hello Everyone.

Since i upgraded my laptoop to last version of BIOS it has lot of power issues, here some:
- Turn on when plug AC input
- Turn on when plug battery in (without or with AC plug, doesn't matter)
- Turn on when i press any keyboard button
- Seems to be always in Hybernate mode, even I choose power off. 

I tried (really, a lot!) to downgrade the version of my BIOS. It is virtully impossible. Neither by software or trough win+v+powerbutton.  Win+b returns to me a black screen an a blink caps lock. 

Is there any chance of HP release a new version of this bios or have a Windows tolls to downgrade the BIOS? I have a some love for this laptop and this issue is completly anoying.
