I'm a Lenovo Thinkpad X1 owner. I was using Linux Mint 13 for a few months, but a few days ago, I decided to switch to Xubuntu 12.10. Of course, I expected better battery life and less power consumption, because of XFCE. Unfortunately, things went terrible and now, the power consumption in IDLE is between 20-30W!!! While using Linux Mint, the consumption was 8-9W on average. I think I tried everything possible, for example http://29a.ch/2011/10/14/review:-ubu...on-thinkpad-x1 but nothing helps. I'm really disappointed and I have no idea what to do next. Battery life is very important for me.
Please, could anybody help me? Even if a guess, what could be the problem.
Thanks a lot.
