My notebook is a Compaq Pressario CQ71. The battery life is like 1:45 h. When Win Vista was installed on it, it was like 3 h. Now I like Linux more, but this distribution (ubuntu 12.04) is consumes too much power. So, what linux distribution is less power hungry than ubuntu 12.04?

Besides being less power hungry the Linux should be have the same graphic effect option (compiz, cairo dock, ...) like ubuntu 12.04.

Thanks in advance.

Regards

Very good post! The display's brightness is by default on the maximum. Control it with FN + F6 or FN + F7. –  IndexOutOfBoundsException May 22 '13 at 16:40

Short battery life is a problem faced by many Linux users with laptops or nethooks. This is because Linux is always using high performance mode, while Windows adjusts performance when using battery. To solve this, a small applet called Jupiter was created. It allows you to set the performance mode of your computer, so you can get more of of you battery.

To install Jupiter in Ubuntu 12.04, go to Terminal (Control - Alt - T) and type the following commands:

sudo add-apt-repository ppa:webupd8team/jupiter;
sudo apt-get update;
sudo apt-get install jupiter;

When finished, you can launch Jupiter from the Unity Dash or add it to your startup applications.

power saving application similar to Jupiter? < askubuntu.com/questions/285434/… > –  Qasim May 23 '13 at 2:00
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw

After installing the above you need to start it using:

sudo tlp start

I went from using jupiter from 1 /12 - 2hours from my laptop im using the above tlp now which is replacing jupiter and im getting 3-4 hours now beating windows battery life. Also consider having a look @ indicator-brightness.

sudo add-apt-repository ppa:indicator-brightness/ppa
sudo apt-get install indicator-brightness

I set my brightness to around 4 which is perfectly clear enough-

You should at least double your battery life with the above methods.
