Comment 8 for bug 921714

Confirmed, it seems as though the CPU Frequency is locked to the highest setting?
BTW I have installed a unity applet that allows setting a lower CPU speed, this seems to allow things to cool down allot while still being usable. It is not a fix as the apps are not reliable and rely on user intervention to prevent possible hardware damage, they are mainly for extending battery life if your away from your charger etc.

Anecdotally I don't remember my laptop manifesting this power frequency bug with Ubuntu 11.04 and Ubuntu 10.10 and 10.04, so I believe it is a bug introduced in 11.10?

I also have an intermittent issue where by folding my MacBook 2,1 up while on battery fails to put the laptop to sleep. I had this last week when I found my rucksack was warm and found my laptop had been left fully powered (CPU frequency at max) while stowed away in my bag without any ventilation (for about 2hrs)! I'm not sure whether this should be part of this bug or a new bug?
