Extending ASUS Eee PC Battery Life Without Changing From Ubuntu 11.04

25th May 2011

It might just be my experience of the things but I do tend to take claims about laptop or netbook battery life with a pinch of salt. After all, I have a Toshiba laptop that only lasts an hour or two away from the mains and that runs Windows 7. For a long time, my ASUS Eee PC netbook was looking like that too but a spot of investigation reveals that there is something that I could do to extend the length of time before the battery ran out of charge. For now, the solution would seem to be installing eee-control and here’s what I needed to do that for Ubuntu 11.04, which has gained a reputation for being a bit of a power hog on netbooks if various tests are to be believed.

Because eee-control is not in the standard Ubuntu repositories, you need to add an extra one for install in the usual way. To make this happen, launch Synaptic and find the Repositories entry on the Settings menu and click on it. If there’s no sign of it , then Software Sources (this was missing on my ASUS) needs to be installed using the following command:

sudo apt-get install software-properties-gtk

Once Software Sources opens up after you entering your password, go to the Other Software tab. The next step is to click on the Add button and enter the following into the APT Line box before clicking on the Add Source button:

ppa:eee-control/eee-control

With that done, all that’s need is to issue the following command before rebooting the machine on completion of the installation:

sudo apt-get install eee-control

When you are logged back in to get your desktop, you’ll notice a new icon in your top with the Eee logo and clicking on this reveals a menu with a number of useful options. Among these is the ability to turn off a number of devices such as the camera, WiFi or card reader. After that there’s the Preferences entry in the Advanced submenu for turning on such things as setting performance to Powersave for battery-powered operation or smart fan control. The notifications issued to you can be controlled too as can be a number of customisable keyboard shortcuts useful for quickly starting a few applications.

So far, I have seen a largely untended machine last around four hours and that’s around double what I have been getting until now. Of course, what really is needed is a test with constant use to see how it gets on. Even if I see lifetimes of around 3 hours, this still will be an improvement. Nevertheless, being of a sceptical nature, I will not scotch the idea of getting a spare battery just yet.

    Alternatively, install granola. It is proprietary, but no cost for personal use and seems to work well.

    Thanks for this, I couldn’t remember what the name of the eeepc utility was. I have it installed now though. It’s kind of odd that you are only getting 4 hours or so of battery life. I have an Asus 1000HA and get around 6 hours with no modifications. The eeepc-controler increases it to around 8. Of course, I have another advantage I like to use for conserving battery life. I am blind, so I have installed a program to turn off the screen which gives me about 2 more hours of battery life.
