Windows 7: Power Buttons settings, not allowing to hibernate

My laptop (running standard Windows 7 HP) seems to miss the option to hibernate. In the power button settings (not sure if I call it correctly, I have a different language than English set in Windows) all the options to choose actions for power button, sleep button and lid close are greyed out. There is a message saying enable changes or something like that (with the Admin-shield icon). Even from the administrator user, after clicking the message the options remain greyed out and a new message appears saying something like "options can't be loaded" and redirects me to Windows help, which of course doesn't know anything.

I think this has something to do with the fact, that the notebook is Samsung. It was promoted to extremely fast wake up from sleep (which it does), but my suspicion is that the pesky engineers disabled the hibernate somewhere. Even in the Start menu the Shutdown roll-out menu has sleep set as default option and hibernate is missing from the list.

It might be something with the Group policies, however Home Premium does not support group policy manager. Due to this fact, I tried to modify the registry myself, without the editor, which resulted in much bigger problem than before... Now the power button settings don't show anything (shame on me for not making backup of the registry). I would love to post some screenshots, but the registry change blew it all up.



Thanks for help in advance, Michael
