Please help Jorge Castro i don't want to remove Ubuntu but this heating problem, if not solvable, gives me no option but to remove Ubuntu — Mysterio, Oct 19 '11 at 16:40

You know, i noticed that my nvidia PC is slower at graphics with unity3d. And a lot faster with unity2d. You may want to try running unity2d for a test.
Meanwhile read this: http://www.webupd8.org/2011/06/linux-kernel-power-issue-fix.html . Do it and test your results.

I read that yesterday but I didn't want to mess with my Grub settings – Mysterio Oct 19 '11 at 16:53
It's really not a problem. I do it on any machine i have. You can revert grub settings very easily. But you decide. – alex Oct 26 '11 at 11:43

Searching for this model laptop reveals this forum thread talking about how to manage power on that laptop.

First install the utilities:

sudo apt-get install cpufrequtils

Then set a conservative governor:

sudo cpufreq-set -g conservative

According to thinkwiki:

They differs in the way they scale up and down. The ondemand governor switches to the highest frequency immediately when there is load, while the conservative governor increases frequency step by step. Likewise they behave the other way round for stepping down frequency when the CPU is idle. The conservative governor is good for battery powered environments on AMD64 (but may not work on older ThinkPads like the T21). Ondemand may not work on older laptops without Enhanced SpeedStep due to latency reasons. Anyway, for recent enough Intel CPU, ondemand is the one recommended for power efficiency (over userspace, and even over "powersave") by the Intel's kernel developer Arjan van de Ven

Though that might be a little bit out of date. You might want to try it and see how the laptop runs for a while.

Oh that's some KDE specific thing, updated my answer – Jorge Castro Oct 19 '11 at 17:34
Ok does this method mean the CPU will work below its optimum ability? – Mysterio Oct 19 '11 at 19:27

Marginally cooler but still hoter than Windows 7 – Mysterio Oct 20 '11 at 17:49
