ubuntu-laptop-battery-lifeBattery Draining is a serious issue on many Linux Distribution,Especially with the newer distributions like Ubuntu 12.10.There are few apps like Jupiter to tackle the battery draining issue but here I am introducing a application called TLP which is much more powerful in saving battery life than its competitors.

TLP is a powerful command line tool which is very effective for Advanced Power management on Linux powered Laptops.TLP applies the settings upon the system startup hence its much more effective then the other power management applications.

TLP is available for all the major Linux distributions such as Arch Linux, Debian, Fedora, Gentoo, openSUSE and Ubuntu.Here is a big list of advanced Power settings which will be modified by TLP to increase the battery life.


Before getting into the installation you need to make sure that

No user specific power management scripts are running ( look at /etc/rc.local )

Remove the laptop-mode-tools using the following commands

sudo apt-get remove laptop-mode-tools

Installation on Ubuntu and Linux Mint

You can install TLP using following commands

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw

This application will automatically start at the system bootup,So use the following command to start it for first time without reboot

sudo tlp start

You can add some extra features by the following commands

sudo apt-get install smartmontools ethtool

If you are using Sandy bridge or other newer models then install the following application also
