After being in development for 8 months, TLP 1.3 was released with a new configuration scheme, tlp-stat improvements, and a workaround for laptops reporting incorrect AC or battery status, among others. TLP is an advanced power management tool for Linux. The tool comes with a default configuration optimized for battery saving, so it's very easy to use - just install TLP and you can forget about it. TLP is highly customizable though, so in case you want to change some of its settings you can do that too (this is done by editing the TLP configuration file).
