Hello!
Some days ago I heard about this project and tried to optimize my laptop with
respect to its power consumption.
I used the hints from the homepage regarding intel915, dhcdbd, etc.
One thing I noticed is a fair amount of wakeups caused by kded which manages
the KDE services. Killing it solves the problem. ;)
My current result has no real high peak but a very wide base field. ;) Do you
have any hints about further optimization?
Greetings, Johannes
