Hey VideoTrack,
ok, then I understand at least, why many ppl here couldn't see the problem at all.
I do a lot of different things on my PC during the day, but I don't work constantly on it. That means in my case either having to boot and shut down the PC many times a day (too unconvenient) or manually going on low energy a lot of times during the day (which I definately would forget most of the times) or wasting a lot of energy (= costs a lot of money and is quite "ungreen") or, well, using a Windows energy plan with a short time-setting.
