Yes I have, both in the Group Policy and on the individual client machine. I've Opened up the policy by giving full rights to Everyone, the individual users etc.

If I change the registry value on the client, for example, choosing which scheme (0-4) it will always revert to some type of default power scheme.

I'm also logging onto the client machine as Administrator and even that account can't control the power settings...

So, to answer you question, I have tried editing the reg values in the GPO and on the clients and have tried opening up permissions on the GPO and clients.
