Hi Verdi,

A while ago I read this article written by softpedia. I've tried all their suggestions and I notice that I gained around 1 hour of battery life.

Often I would find my self getting a couple hours less battery life in Ubuntu than I would in the Windows based counterpart. Recently however, I was watching the Linux Action Show (as I often do) and they were talking about power management and battery life optimization. They mentioned that, in many occasions, by just installing the laptop-mode-tools package, your laptop would get an extra hour or so on battery. Furthermore, you could increase your battery life even more by installing an application called PowerTOP. This application goes and shows you the individual application called processor wakeups and gives you a rough generalization on if specific applications are being power efficient or if they could still be further optimized.
