I am the administrator and only person on this PC, an HP Presario P6520F. I want the power savings to never go to sleep or hibernate. I have changed the setting again and again. I've tried setting it to 5 hours in case it is over-riding never. I have tried several on-line tutorials, but somehow the settings do not change. I assume there is a sleep/hibernate setting somewhere embedded in the software. I also tried to get it to not require a password when it wakes up from sleep, but that setting also does not hold, so I removed the password. Perhaps it's just not letting me do administrator actions, even though the icon shows up with me as administrator. Any help would be greatly appreciated! Thanks.
