lets try the html output.... if the html output is not enough I need to enhance it ;-) (the idea of the html output is that it should contain all the information needed to diagnose power issues... making it easy for reporters and easy for the support guys (or developers) because all the information is easy to get, and just there) > - powertop only shows power drain, no longer shows how many hours of > battery I have left is this feature appreciated?

Kernel bug? I think you actually have something keeping the device busy! lsof should show which one (and I should make PowerTOP just print this information suppose) > - the power saving tunable for wlan0 is not working, pressing enter > keeps it in the bad state, also that tunable shows up even if rfkill is on interesting; hopefully powertop.html will show which wireless LAN device you have ;-) > - powertop can't make up its mind how much power my CPU fan is using, > it has shown 0 W (and system base estimate of 5W), then a bit later it > has shown the fan using 8W (and entire system using 8.x W, system base > estimate of 0W). I guess this is because fan can't be turned off to > measure its usage, but it still is confusing the measurement/estimation is constantly evaluated. I take it you have a thinkpad? If the estimate is unstable maybe I need to "dampen" the estimator a bit more for it. (fan's have been the hardest to get working well.. their power is a 3rd order polynomal with the RPMs, due to the physics of moving air with a rotating thing. 3rd order polynomals suck for least-square estimators since they're not always very stable) > - I don't see per-process GPU ops as on the screenshot in your blog, I > only see GPU ops on the device tab.
