Optimize power consumption while running on battery
Currently, openSUSE 11.3 does not much to preserve my battery while being unplugged. Intel's powertop came up with many good suggestions that cut the power consumption on my laptop in half! It would be quite a good idea to make the powersave profile do a little bit more than just dim the screen and throttle the CPU. Other suggestions:
- turn bluetooth off, radio is always a battery eater
- reduce USB polling
- enlarge write cache
- ...do other things that reduce wakeups to a minimum
Mobile usage is more and more a key scenario.
Set user benefit
You can add different relations here, for example duplicate features, obs projects, urls...
To embedd an image you can simply upload it to paste.opensuse.org and add a relation to its raw url.
Set release notes
The powersaving script sets all hardware components to save powersaving modes but skips critical settings like USB suspend which could cause trouble.
The max performance script reverts all settings previously made by the powersaving script.
