Control CPU frequency using CPU Frequency Applet

Do you know that you can manage your CPU in Ubuntu, like how fast they run and how much they consume your laptop battery? If you don't know, now you must watch this post and enable it. Why? Of course to control your CPU so they won't consume a lot of energy, so you can have more time if you're using your laptop if it's unplugged.

It's very easy, just go to one of your panel, and right click there and choose "add to panel...". Now, an window will appear and from there you can choose which item you want to put into your panel. Now, search for "CPU Frequency Scaling Monitor" and when you found it, choose and click add button.

Now, an icon (like a chip) will apperan on your panel and from there you can adjust your CPU frequency. In my case, if I click on it, a drop down menu will appear and this is some option for scaling frequency  2.27 GHz, 1.60 GHz and 800 MHz. Now, about modes for scaling your CPU. In my case, there are four option: Consevative, Ondemand, Performance and Powersafe. Now I'll explain a little bit about these 4 option. After I search it on Google, I found it and I'll share it to you. Thank you to hubpages for the article about this.

Conservative : start with the lowest frequency and you CPU will go up if needed and stay there. If your CPU still need more, then it'll go up again to the next available frequency until it maxes out.

Ondemand : start with the lowest frequency and will go up to the highest frequency if the use of your CPU increased.

Performance : set your CPU to the highest frequency and stay there forever.

Power safe : set your CPU to the lowest frequency and stay there forever.

Now, understand? If you want to save your battery life, set your CPU to low frequency. Easy, right? Try it now :)
