Laptop over heats
 
Hello,

I am using Debian Squeeze on my laptop and since I am using it my laptop over heats and turns off itself because of the over heat.

My fan seems to be working but, it doesn't seem enough because my laptop is always hot, I use to have Windows 7 on this laptop and did not have this problem with it.

What is the problem? I have installed sensors detected and it reconizes my intel fan but, still it is not enough!!

Can someone help and tell me how can I fix this problem.

Cheers!

I think that your problem is that this is a laptop with Optimus technology that is currently not supported by Nvidia for Linux.
Sorry, but I can't help with that.

Hello,

I been researching and it seems you are right my laptop has the "NVIDIA Optimus Technology", so it seems that in Linux there is no support yet on this technology, the only thing that I am not sure if this is why my laptop overheats?

It seems that the only solution I got left is either go back to Windows 7. Can somebody confirm if it works on FreeBSD or any BSD? I prefer that before going back to windows.


Cheers!

Most likely the Nvidia-GPU will not get into power save mode, heating up the laptop. There is a project called Bumblebee working on enabling Optimus on Linux, but since I don't have an Optimus laptop I have no experience with that. May be that can solve your issues.

Hello mate,

thanks a lot you were completely right, the Bumblebee project completely solve my problem, if any one else has this problem that I bet someone would have here are the steps I did to solve it:

http://suwako.nomanga.net/ on this website you have the steps to solve it but, don't forget to install VirtualGL because it gave me a dependency problem but, installing it from here http://www.virtualgl.org/DeveloperInfo/PreReleases solve my dependency problem.

Thanks a lot, my computer runs smoothly now no overheating before I can put some eggs on it to fry, lol

Cheers!!
