Comment 161 for bug 760131

Even if that were so, when my laptop goes into battery mode, with all of the aggressive power saving modes throttling the CPU, etc, it's unacceptable for it to be running so hot. I wouldn't normally care if it's plugged in and sucking up power, but when the power is supposed to be scaled back, it shouldn't be taking up more power ( even at the cost of decreased responsiveness.)

In any case, as of yesterday, after a kernel update, my laptop is now consuming 14-17W of power when on battery, as opposed to the 19-25W it was taking last week. While not as good as the 11-14W range I had going with Maverick, it's an improvement. I don't recall seeing anything in the kernel changelog that would indicate a change to the power consumption, but I'm not a kernel expert. In any case, I have not altered any of my power saving optimizations between the two tests, and I had used the force acpi trick much earlier on.

If it stays this way for now, that's not a bad sign.
