Recently I have installed openSUSE 12.3 on my Lenevo U410. I am using Windows on this machine too. But when I using openSUSE I realize that my laptop get much hotter than what is it in Windows. I also used Ubuntu before openSUSE. Ubuntu works fine, but now my fan works a little.

Do you know how to solve this?

What's the source of the issue? Try checking the sensors for temperature to be able to tell. My wild guess it's the GPU - if it's so, check which driver is used by Ubuntu (lsmod | grep -P 'nvidia|nouveau') and which in openSUSE. If it's the same, you may want to investigate powersaving settings. – TNW Apr 14 '13 at 10:04
sorry for delayed answer. My sensors works well. I am using sensors command and get the temperatures correct. And all of them is working. About the driver, I search and find that driver. But is there a problem with using discrete GPU. My laptop has a intel GPU onboard and nvidia with optimus technology. (when laptop is idle it gets hot too, so I think this is not about GPU). – Ramyad Apr 14 '13 at 18:48
I rather meant whether you know what is making your laptop so hot. – TNW Apr 14 '13 at 18:50
How can I check my power saving options? – Ramyad Apr 14 '13 at 18:54
Lenovo has a tool on windows. I changed it to maximize battery lifespan and therefore my battery has a strange charging behaviour in both windows and openSUSE! Is there something like that for power saving? – Ramyad Apr 14 '13 at 18:56

I have finally find the problem. The problem was from my discrete NVIDIA GPU. OpenSUSE 12.3 found it and all the drivers were good, but I do not know why its gets hot. I think the main problem is from Optimus technology (I have some display problems with it in Ubuntu 12.04 too!). Since I am not using my discrete GPU in Linux, therefore I have disabled it. There is two way to do this:

1.if there is no BIOS option to use UMA GPU only we must install bumblebee and required packages and then turn off discrete GPU.

2.if there is a BIOS option, we can disable Optimus. (there will be no problem with windows since it use UMA for all programs except programs you defined as "run with high-performance NVIDIA's GPU". So you can enable it from BIOS and come back to run them)

first solution: do instructions from here

second solution: go to your BIOS and disable optimus. Then come back to linux and delete all nvidia packages. Check your hardware and make sure there is no nvidia's GPU

another point: you can install YsST power management package for better controlling over power savings and therefore fan and temp of your laptop. Instructions are here

I hope someday linux will support optimus technology like windows!
