Thinkpad W500 - heating problem

Asked by Nataraj M Basappa

First thanks, for all the people involved in brining in UBUNTU. I had contemplated long enough to switch my
primary computer to UBUNTU and after release of 10.04 couldn't hold myself, I even convinced my wife
that it would be much better than windows 7. But I am facing this heat problem, seen only when battery is fully charged
and still on AC power. I have searched google, for possible solutions like CPU scaling and ACPI and so on and still not able to find a my way in reducing heat. Any help appreciated and would file a bug if required be.

System Details.
Thinkpad W500 - 2.8 Dual core
9 Cell Li battery
No other OS installed.
Xorg - running on ATI open source driver with 3D enabled.

Hi :)

I am not sure about this issue and suggest also posting a question in
http://www.linuxquestions.org
http://www.ubuntuforums.com
This is usually the best place to ask but sometimes it helps to cast the net a bit wider. The first of those links is a general linux forum, not just Ubuntu because i have a feeling this is a kernel issue so someone from a different distro might be able to help. I think the issue is about being able to under-clock (rather than overclock) the cpu and i am not sure how to go about anything like that. Also i seem to remember aother question about this sort of thing with another machine in the same series.

Sorry i haven't been much help!

PS on a side issue it is worth running through the medibuntu worksheet to try to sort most of the multimedia issues in one go

PPS also this link might be useful generally

Tom,
 Thanks for your support, I got it solved to a greater extent and my laptop temperature is relative (I am not putting figure here as I my laptop most of the time keep it on my lap) to that of what my windows 7 use to run. Trick was with installing laptop-mode-tools, which was not installed by default it seems, as its been dropped from default list from 10.04 (read that info from Ubuntu online docs).
