[Pertains to Microsoft Operating System]

For XP Pro, I'm looking for a simple script/reg file which will allow me to easily change Power management from... say... "Always On" to "Portable/Laptop" setting just by clicking a simple icon, AND another script/reg file to change it back.

Reason:
Since I'm on a notebook, I seem to change my settings a couple times a day, at least, so I'm tiring of all this clicking for just a simple change.

Anyone?
