I've recently installed sid on my (new) Toshiba U840 laptop, having completely ditched the windoze install. The one big thing is battery life. It has gone through the floor.
Under win it was typically about 5-6 hours. Under sid it is down to a couple of hours.
What I think is happening (although I have no proof) is that when it goes into suspend or hibernate, it isn't properly powering down.
Is there some sort of tool that I can install that monitors power usage (and preferably what is using it.) Maybe that way I can get to the bottom of the problem.
