Battery life optimization

view story

http://crunchbanglinux.org – After installing Crunchbang 9.04.01 using the scripts from a minimal Ubuntu install I've noticed my AA1's battery life is uhhh, not so good. 1 hour 45 minutes not good to be exact, which compared to UNR9.04 and Crunchbang 8.10 is a bit sucky, as I was getting 2 hours plus off both.I was wondering if anyone has any tips for reclaiming a few more of those precious watts? I've made sure laptop-mode is running already, and I've run lm-profiler and disabled the recommended daemons but I'm sure I can squeeze a bit more out of it! (HowTos)
