which netbook Linux distro manages battery power best?


I just bought a System76 netbook off of ebay. The battery is supposed to last 6-8 hours, but I only get around 1.5 hours. I partitioned the drive into 9 slices and installed Ubuntu/Xubuntu/Kubuntu netbook editions for 9.10. It comes with a nice power manager but I'm not seeing results. The netbook run an Intel Atom CPU and was designed to be used with Linux.

I have space on the drive for more Linux netbook distros to try. Would another distro mangage my netbook's battery usage better and which ones?

I'd give Fedora 12 a try. They had a considerable push to reduce power (idle sound and USB ports, spin down drives, etc.). Apply maintenance after installation, as there were a number of fixes. Also, set your display to dim then power off quickly on idle if you want to save power.

You have your choice between the LXDE and the XFCE spins, here.

I am running KDE 4.3.4 on ArchLinux
Computer: HP Compaq 8510W (not a netbook, but the power management principles are the same)

After some extra package installs for the CPU clock scaling, power management is working perfectly. Assuming that you use a DM (KDE, Gnome or XFCE), then it's the choice of DM that dominates--not the choice of distro.

I've been using XFCE in Ubuntu most of the time and watching my battery drain. I want to put LXDE in Fedora Core 12's spin next to Xubuntu and see if it makes a differenced or if I need to consider paying a $100 for a new battery.

Perhaps we should clarify that---regardless of what system you are using---you need to configure the settings. Have you done that?

For battery power savings, it's not just about configuration. Fedora has added a large set of patches to applications and system services to reduce wakeups and prevent spinning up idle drives. There were also patches to power off idle USB ports and the sound subsystem. All have been pushed upstream, but it can take a few months until they work their way back down to distributions that are further from the bleeding edge.

The configuration stuff may need to be done (though most is automatic when the power manager detects battery operation these days), but that only gets you about half way.

yes I have set the power settings as much as I can in XUbuntu but I'm thinking (hoping) that there's a runaway process that is draining the battery. Maybe wicd is always looking for connections when I am not connected to the internet?

Try a minimal installation without Xorg.
Add Xorg from the repositories. Use the package manager to remove the modules that you don't need.
Try a lighter desktop such as etoile, gnustep/window maker or on of the boxes. Use the cpufrequtils or cpuspeed to adjust the running requency.

There is also tiny x which you can build and save.
