I recommend visiting https://wiki.ubuntu.com/Kernel/PowerManagement/PowerSavingTweaks and if you want to go further and identify power sucking apps also visit: https://wiki.ubuntu.com/Kernel/PowerManagement/IdentifyingIssues

Try to install Jupiter. It works fine for me. You can grab it from PPA:

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. –  user61928 Oct 3 '12 at 11:14
    
If this PPA will removed my answer will be completely unusable. Because my answer is "Try to install Jupiter". –  martini Oct 3 '12 at 14:38
    
ok just improve your answer then insert the link –  user61928 Oct 3 '12 at 14:40
    
@martini If the Jupiter PPA is removed, it will still be possible to install Jupiter, through other methods. In that circumstance, an answer explaining what Jupiter is and why you recommend it for this purpose would still be helpful. You might choose not to expand your answer further (and that's OK), but I still would consider maythux's advice to be good, and applicable to this situation. –  Eliah Kagan Oct 4 '12 at 7:03
    
@Eliah Kagan ok, ok. Answer was improved already after maythux's comment :) It was consisted of only link and no text before. –  martini Oct 4 '12 at 14:25

This article answers you about ubuntu 10.04 needs more power

There are many tools that you can use for reducing power consumption like:

1.powertop

sudo apt-get install powertop

2.jupiter

Download and install the latest *.deb file. Launch it from the menu. It will create an applet in your tray, when you right click it, you will see what it does for you

3.MicroMiser

4.From Ubuntu software center, search for laptop-mode-tools and install it.
