How to Install TLP on Fedora 20 for Battery Management

You can use the default battery management with Fedora or can use TLP which is better at managing battery life on laptops.
TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it.

You will need to have rpmfusion installed and will have to download tlp from their site.
Open a console and type as root or with sudo:

$ sudo yum localinstall –nogpgcheck http://repo.linrunner.de/fedora/tlp/repos/releases/tlp-release-1.0-0.noarch.rpm

$ sudo yum localinstall –nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm

$ sudo yum install tlp tlp-rdw

To manual start (after reboot it will automatically start):

$ sudo tlp start

To check the status:

$ sudo tlp-stat

$ sudo tlp-stat –battery
