hello!
i have just installet Ubuntu 13.04 on my Samsung RC-530 S02, and I'm liking it very much. but i have one problem I would like to solve: i m noticing that this new OS is consuming too much energy. before installing it, i used ubuntu 12.04, and my battery life coult reach 6 hours (if i kept mininum brightness). now it hardy reaches 1 hour and 45 minutes. furthermore, i can hear that the PC's fan is working much more than before. can I do someting to change this?
thanks
