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.

The friendly Old Battery Warning in Ubuntu

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.

Using lsb_release to get Ubuntu release information

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.
