Disabling "allow this device to wake up the computer" just for the mouse helped! Thanks ijwcomp! My mouse is not wireless and I didn't think it does something while it's not moving and clicking, but it has been turning the PC on. The keyboard doesn't have that problem, "allow this device to wake up the computer" is enabled and now I can turn the computer on after hibernate by pressing any button, just as I like it . 10x again!
