I found this little application and you must use it!
Its called LocalCooling and it enables a somewhat decent power saving scheme. You can do the same with the Configuration Panel or Dell Quickset, etc.
But where it does differently is that it tells you how much electricity you are sucking up by using your computer and keeps statistics on how much power you're saving using it. It is an eye opener, and it has a feel-good side to it.
Oh, and it doesn't annoy me like QuickSet does...
So, please install this on your machine and save saving electricty, money, and emissions!
