Hi, I have two laptops, one an Acer running Vista Home 64bit and the 2nd a Toshiba Satellite running Vista Home 32bit. On my Acer 64bit, when I unplug the AC it automatically switches from High Performance to Balanced without me doing anything. I like this, is there any way to do it on my Toshiba as well, it does not automatically do do so...THANKS!
