Power Management in Ubuntu

[Verdi R-D]

Hi everyone,

For the past many years I've been using Ubuntu, power management wasn't 
great. 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.

Being as I've obviously been living in a hole the past couple of years, 
does anyone have any other tips on optimizing/getting more battery life 
in Ubuntu?

Thanks,
Verdi
