Power Option Properties -> Power Buttons

I'm trying to find the reg file or powercfg command that will change the power buttons property to Stand By in windows xp. I'm using the powercfg options in .cmd to set up a new power scheme and was able to set up everything but this option. I thought it might be in the registry under one of the AC/DC policy settings but whenever I export any changes then try to test/reapply them it doesn't change. Is there a powercfg command or registry key I can add that will set this option to stand by or is it located in one of the policy binary keys?

Thank you for any help
