Changing Power Plan while connected remotely

[private_meta]

Hi, I've been looking everywhere for a solution to my problem: I want to change the power plan on my notebook running Vista while connected remotely. All I found about this problem was "Log in as administrator", but I already am. Can someone give me a hint how to change the plan? I would frequently need that feature, but it tells me only the system administrator can change it (which I am) cheers, meta
