One power setting controls shutting down for inactivity. I never use defaults for this, but rather set things at "Never" when on AC.

You could try to download new firmware & drivers from HP.

>Does it shutdown only during inactivity? Yes, it only shuts down after it goes into hibernation, when it is inactive. Nothing will bring it out of hibernation either. I've even yelled at it. That didn't work either! :-)
