A developer of RedHat has created a patch for the Kernel de Linux which reduces the battery consumption of devices with this OS installed. and apparently it has given very good results.
The problem was that as of version 2.6.38 of the Kernel, it was disabled -I do not understand why- by default the module Active State Power Management which has among its functions to reduce energy consumption.
We got the patch and information for this news from HumanOS blog. It has about 60 lines of code and we can see it in the this link. It is very likely that it will appear on the packaging of the version 3.2 of the Kernel maybe we'll see it in Ubuntu LTS 12.04 or other distributions with release dates in early 2012.
The most benefited of course will be users of mobile devices, laptops, netbooks and others.
Thanks for the info! Looking forward to Arch!
In a short time (maybe weeks) we will be able to enjoy it in Arch, as well as in any other distro that is RR 😀
In fact, the patch can already be used. I quote verbatim the news in HumanOS:
You, only you who are a GURU can do this without ending up pulling your hair out.
Happy coming back from vacation, hahahahaha.
Hahaha I'm not GURU man ... I wish I was hahaha. And well, we were not on vacation, rather we were doing the opposite, working hard. Imagine that to achieve that, our boss had to hide the modem router from us, because otherwise we would not detach ourselves from the computer hahahaha
What new! Che could you delve a little more into the issue of installing the patch in the kernel, I can't find clear information on how to apply it (for compiling I manage) and my ASUS k52De really needs it!
Thank you in advance!
Well, the excessive energy consumption is true, the truth is that many times I preferred to start in windows because it marked 7:30 power even on battery and if it started in Fedora or mint it would tell me 4:30 or 0 at most. But then I hold on because I know that we are going to have a patch but in a while, it will first go to Red Hat, and then to Fedora as safe, and from there to the others once the SC is published. or not?
It's my turn to be "superficial": I just wanted to congratulate you on the image you used to illustrate the article: really nice and interesting. !! Congratulations!!
Hahaha thanks it's nothing more than a dmesg with a Faenza icon 😀
Regards!
Has anyone already tried it? what results have you seen?
I installed Jupiter: http://www.jupiterapplet.org/ y
Power Top: http://www.atareao.es/ubuntu/conociendo-ubuntu/ahorrar-energia-en-linux-con-powertop/
And I have improved battery performance on my Ubuntu 11.10
