How to Install and use PowerTop on Ubuntu 15.04

PowerTOP is a power management tool to diagnose the power related issues. It helps to reduce the power consumption and extends the battery life making it more healthy and robust. PowerTOP is built with amazing utilities like sensors, powersave and cpu governer, each one plays its own role and at the end we get a very low power consumption.

PowerTOP also checks the currently running programs and looks over the kernel options and estimates the total power usage, hence it is very helpful for laptop users to get prolonged battery life and obviously for larger server companies to reduce the power costs.

Press the tab key now and go at the end and you will be able to see the Tunables option, this is where you need to look and fix the BAD ones to manage the power consumption.

It is very important to know that whatever changes you will make are temporary unless making them permanent. Don’t worry, its easy too. Run the below command to generate the HTML file:

Making PowerTOP changes permanent

A new file powertop.html is generated that can also be opened in the browser:

The Tuning tab is showing the settings that need to be tuned to manage the power efficiently and we just need to run those commands under the Script heading. Copy these commands, open /etc/rc.local and add in it, the changes will be permanent and will get no affect on reboot.
