Hello everyone.
Long time since did not post something, but now i have a question for all of you , and a bit of help needed.
I have a laptop : Thinkpad Edge 13 ( AMD Neo CPU, ATI video card ). In idle the processor is about 71-75C hot. If i open a website ( youtube ) it rise about 85-90C, and my laptop is very very hot. I know for sure this did not happen in Windows, but i want to stick with Linux, so i need to get this sorted out.
Can anyone help me on this issue ?
Laptop fan is always running, so this is not the case of heating …
If anyone else had this problem on a thinkpad machine with AMD cpu and got it sorted out, please let me know, i need your help !
You did not mention what version of openSUSE that you are using, the desktop that you are using or the age of this Laptop computer. I show that based on the release date of this PC it could be near two years old. Let me say that if you have not already done so, you need to blow out any built up dust in the unit heat sinks around the CPU and anything near all vent holes on this Laptop. I use a can of Duster Spray, blowing it into all vent holes with the laptop shut off, power disconnected and the battery removed. You can really be amazed on how much dust can build up in your Laptop over time and it WILL increase its heating.
I have a couple of blogs that you might want to look at to control CPU speed and therefor the heat it generates.
Thank you for reply.
I Use open SuSE 12.1, and yes my laptop is about 2 years old. However i keep my fan clean.
I will have a look on the utilities you have mentioned, thank you very much. !
Initial workaround to the problems of power regression is to add “pcie_aspm=force” besides existing GRUB boot arguments, this did help to some point but what really helped in both cases was also adding “i915.i915_enable_rc6=1″ or at least I thought so since this line only applies to Sandy Bridge (i3/i5/i7) and latter. In the end my “/etc/default/grub” looks like:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pcie_aspm=force i915.i915_enable_rc6=1”
and make sure you run “update-grub” after making these changes. Besides the arguments I used there are other ones you can use and for more info please head to ”Tweaks To Extend The Battery Life Of Intel Linux Notebooks“.
Results I ended up with such simple tweak are more then satisfactory as I got some ~45 extra minutes of battery life besides the fact that it lowered temperature by some ~10 °C.
Sorry for not getting back. I did not had time to test what you have told me, i was kind of busy.
As soon as i test and have results, i will come back and share it with you .
