I get a bit irked when I see stuff that can be solved but people just complain about it. News.com, slashdot, zdnet … list goes on and on about people jumping on the bandwagon. So you know what, I attempted to fix it. Ok, here is my solution. I spent more time prepping this post than writing the application.

No explanation as to what it does or how it is supposed to affect battery life.

It disables Aero when on battery power. Then re-enables it when plugged back in.
