I've got strange problems with power managment.
When I'm closing my iBook it wan't go to sleep. White led lights for the short time and after that my computer wakes up (of course when the laptop is closed). This happens only when the AC Adapter is pluged in so it's very strange. When I'm using the battery there aren't any problem.
Problem started after updating Mac OS X from 10.3.1 to 10.3.9. Now I've got Mac OS X 10.4.1.
