1. Installation is pretty much very straight forward, which is also one of the main reason I like to use Ubuntu.
$ sudo add-apt-repository ppa:linrunner/tlp $ sudo apt-get update $ sudo apt-get install tlp tlp-rdw
2. Start the program immediately and see the battery status.
$ sudo tlp start $ sudo tlp-stat -b
3. Applying either in battery or ac power mode.
$ sudo tlp bat TLP started in battery mode. $ sudo tlp ac TLP started in ac mode.
