Can't Modify Power Settings

i can't modify my power settings. When i try to change my power plan settings it says that my power plan info isnt available. I then go to the FAQ part and it says "If your computer is part of a network at an organization—such as a school, government agency, or business—your organization's system administrator might have made certain settings unavailable or even removed them by using Group Policy. Group Policy is a feature of Windows that lets system administrators manage users' access to Windows features. If you think that Group Policy is preventing you from changing a setting that you need to access, contact your system administrator."

I have NO idea what this means.. this is my personal computer and is not part of any newtworks. I then tried to change my account type to "standard user" so i could fix the problem, but my computer won't let me. I even created a new user account and made that one a standard user but it didn't fix the probelm. How do i gain access to my power plan so i can modify it?
