Sadly, it seems this isn't helping much. My netbook still idles at ~60 centigrade on and off power. I will verify that before this change I was able to idle cooler when off power just to be sure. I do see the C4 state both on and off power, so that's nice at least. I'm just perplexed why my netbook runs so hot when idle. I even killed X to see if it was really the gpu that was heating everything inside up, but it didn't change anything. -- Chase -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Well, now I seem unable to reproduce the lower temperatures at all... I tried the same kernel without your patches and mostly got the same temperatures. I tried the Ubuntu 10.04 LTS 2.6.32 based kernel and it was two or three centigrade cooler, but not the tens of centigrade cooler I remembered. I also can't see a big change anymore when power is plugged in or not. Maybe it was all a matter of usage in different environments making me think it was related to being plugged into power or not.
