Only tried the "Power Options" tab and set the Power Schemes to turn off the montor, hard drive and put the system on standy after "5" hours. The "Advanced" tab "power" button I set to "ask me what to do" when the "power" button is pressed, and the same "ask me what to do" when the "sleep" button is pressed. The other Power Options - Hibernate, UPS, and Away are not used. Don't know if any of these settings have had any effect on the Energy Star program or not. I have also looked at the "install/delete" program. Deleted a program that said "Energy Star", but it didn't seem to do anygood.
