TLP - Linux Advanced Power Management
TLP saves laptop battery power on 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. Nevertheless TLP is highly customizable to fulfil your specific requirements.
TLP is a pure command line tool with automated background tasks. It does not contain a GUI.
