Add the PPA and install PowerTOP 2.1 using the following commands:</div><pre class="linux-code"><code>sudo add-apt-repository ppa:nilarimogard/webupd8<br />sudo apt-get update<br />sudo apt-get install powertop</code></pre><br />The latest PowerTOP 2.1 source can be downloaded from <a href="https://01.org/powertop/">HERE</a>.<br /><br /><br /><br /><h2>Usage</h2><br />To use PowerTOP, you need to run it as root:<br /><pre class="linux-code"><code>sudo powertop</code></pre><br /><div style="text-align: justify;">PowerTOP doesn't just diagnose power consumption issues, but it can also provide solutions. On the Tunables tab, you can see what you can do to save some power:</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-vahX8SmbwhA/UDyC9dg6UYI/AAAAAAAAJxI/8b6s6iWWN0I/s1600/powertop-tunables.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="powertop" border="0" height="191" src="http://4.bp.blogspot.com/-vahX8SmbwhA/UDyC9dg6UYI/AAAAAAAAJxI/8b6s6iWWN0I/s320/powertop-tunables.png" title="powertop" width="320" /></a></div><br /><div style="text-align: justify;">However, most of the settings are not saved and they are lost after a reboot. You, can, however, make them permanent, by using the commands provided in the PowerTOP html report. To generate an HTML report, run the following command:</div><pre class="linux-code"><code>sudo powertop --html=powertop.html</code></pre><br /><div style="text-align: justify;">This will generate an HTML page which you can open in your web browser:</div><div style="text-align: justify;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-ksV0i7RGxIo/UDyDE4kBfUI/AAAAAAAAJxQ/bIXS21LLiao/s1600/powertop-html.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="powertop html" border="0" height="124" src="http://3.bp.blogspot.com/-ksV0i7RGxIo/UDyDE4kBfUI/AAAAAAAAJxQ/bIXS21LLiao/s320/powertop-html.png" title="powertop html" width="320" /></a></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Here, you can see various information related to power usage as well as a "Tuning" tab where the settings that need tuning are displayed, along with the commands required to apply them. Add these commands to the <i>/etc/rc.local</i> file to make them permanent.</div>
