screensaver miner & changing the Windows 'power plan' to power saver when active

[thomiel]

Currently, I only got a CPU miner at work on my quad core, just symbolic thing.

I love the screensaver version of the rpc-miner. Only thing is, as I have enabled the AMD cool&quite feature, it will double the cpu clock and burn another 50 watts or so when the screensaver starts. I don't want to afford extra energy beyond what my computer uses for normal operation. So I wondered: is there an easy way to switch the energy scheme from balanced to power saver when the scrensaver activates and back to balanced when it deactivates?
