When you are working outside with your laptop, the most important thing that you might consider is to maximize your battery lifetime. This is true especially when you are working on location where AC power is not readily available.

Here are a few tips that I got from surfing the internet to save battery life when you are using Ubuntu (or GNU Linux OS in general) :
Being a relatively newcomer with Desktop + Web apps application, I tried to experiment with Mozilla Prism in a newly installed Ubuntu Hardy on my sister’s laptop.

Ubuntu is friendly enough to provide a nice and friendly warning to me about the status of the laptop battery that I currently use. With Microsoft Windows (at least Windows XP), the laptop simply dies when the battery looses its juice.
