First off, thanks for working with me. I've tried to solve as many issues as possible by seeing what is already posted, but this issue seems to be rare. Yes, the sensors are not working. I've tried ksensors, acpitools and i8k. Including the applet, all have been fixed at 75C regardless of what actual temp is. I tried using the new Nvidia driver which gave the video card temp, but that driver caused all kinds of other problems which lead to me eventually going to the legacy driver for my old setup. The lack of sensors is an issue I have not been able to work around and is probably related, but my laptop in general seems to want to at least start up in battery mode. Very strange. I wonder if running off of battery activates some mode which is otherwise turned off...?
