Comment 36 for bug 177646

Pehaps it would not save energy for the CPU. But I assume the CPU does not heat that much when running with 500 MHZ or 1 GHZ instead of 2 GHZ. So, perhaps it does not save the CPU-power consumptions, but it saves the cooling devices + it saves on the long term the material. Saving the cooling devices on a Laptop means in most of the cases to avoid fan-activity ==> no power consumption on the fan => power saving.

I see it more or less the side-effect a reduced CPU-frequ has on the overall system. AND therefore I would like to have it enabled.
