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.
Typical laptop might last from 1.5 hour to 3 hours of normal use. So you might want to squeeze out all the battery juice and put it to good use.
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) :
Though Wubi is only officially supported on Ubuntu Hardy Heron onwards (8.04), there is a trick exist which enables you to install Ubuntu 7.10 on Windows using a discontinued binary released by Wubi Installer project.

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.
Its nice to have this sort of reminder when you really need to change the battery.
Sometimes when you are about to ask questions or to get help about something related to your Linux computer, you might be asked which distro and the release of the distro you are using.
Same goes if you need to fix something or install binary packages on someone else’s computer. The first thing you should know, is the name of the distro and the release they are using. The simplest way is to use “lsb_release” command, which are included on most modern GNU Linux operating system.
Just run : lsb_release -a
And you will be given information you need to install binary packages, submit a bug report or to determine which solution best for the particular distro.
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 7.10
Previously I’ve published how to upgrade Ubuntu Linux operating system to the latest release using “upgdate-manager” tool. But what if the computer you are upgrading does not have internet connection ?
Upgrading to Hardy Heron without Internet Connection
- Download and burn the alternate installation CDROM
- Put it in your CDROM Drive and follow the instruction
- If nothing happened, you can launch upgrade manager by typing :
gksu “sh /cdrom/cdromupgrade”
That’s all hope you can enjoy the latest Ubuntu 8.04 LTS release !
