nvidia gpu aggressive power saving in battery mode?
 
I have nvidia geforce 102m based graphics chipset in my laptop running ubuntu 10.04 and nvidia binary driver. When the laptop is running off on AC power with dynamic power switching/gpu speed running at lowest speed the temp is around 65 degrees C, when I switch to batttery the temp drops to 55-56 degrees C. Both seem to provide same level of performance but the gpu seems to get less hot in battery mode. Is there any way to tweak to achieve same level of optimization in AC mode?
