Just installed Ubuntu on my laptop. What is weird is that my battery life has become shorter, and when I try to charge it, it said that my battery will be full in 8:30 hrs. While on my Windows, it only take less than 2 hrs make it full.
With the Update from Friday 09.12.2011 this problem should be solved. I Had the sam eproblem and now my battery time is longer than 2 hours and loding is much faster.
I hope the update will help you ;-)
