Comment 166 for bug 22336

Hi Rob,

If I'm running any kind of power management it's not intentionally. Anything I know about power management and Linux (or Windows) I learned in the last few days - it's always been a topic I've been happy to ignore. I swear I didn't deliberately touch anything to do with power management until after the problem appeared.

Actually, as a side note, I don't even have anything under the directory /sys/devices/system/cpu/cpu0 except topology, so a lot of the stuff people are talking about above can't be applicable to me.

I did clean out my fan and it is running better now. I reinstalled Ubuntu successfully and I am having no problems now. Of course, I also have not allowed the battery to fully charge yet to try and test my theory again. But the problem came and went away in a fashion that could not have anything to do with anything I had installed, or any problem with my fan - I was still having the problem trying to use the LiveCD (system stopping under what could never be called an excessive load, just starting Firefox would do it), and it went away when I allowed my battery to drain a little, again running from the LiveCD. I can't think of any good explanation for this. It seems like the battery is fully charged but I have a battery icon rather than a cord icon in Gnome, FWIW.

The fan is speeding up and slowing down with load just like I was used to it doing on Windows - maybe my BIOS is taking care of this?

Here is my output from acpitool -e with a fair number of things running:
