Improve Battery Life Using TLP.
#-Link-Snipped-# is a power management tool for Linux. It brings you the benefits of advanced power management without the need to understand every technical detail.TLP does not replace but enhance the existing power management of your Linux installation. TLP applies it's settings upon system startup and on every change of the power source.

How To Install :

1) Remove User specific power save settings & scripts.
(You will find the script in /etc/rc.local)

2) Remove Laptop-mode-tools.
```
 sudo apt-get remove laptop-mode-tools 
```
3) We have to add third party TLP-PPA as it is not available in any distro's repository.
```
 sudo add-apt-repository ppa:linrunner/tlp 
```
4) Then update the source.list
```
 sudo apt-get update 
```
5) Installing TLP.
```
 sudo apt-get install tlp tlp-rdw smartmontools ethtool 
```
6) Start TLP.
```
 sudo tlp start 
```
It's easy to install & very good tweak for Laptop/Netbook users. 👍

Open up the script & tell me what's the script in it.
If there ain't any script in it then ignore it & move further. If there's any, then remove it.

If you're using Sandy bridge or latest one architecture then don't forget this :
```
 sudo apt-get install acpi-call-tools 
```

This is there in the script..

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
 
exit 0

Which means you haven't added PPA properly.
Go to ubuntu Software center --> Edit --> Software sources --> Other Software.

Show me it's content.

If you don't know how to add PPA, read : <a href="https://www.crazyengineers.com/threads/adding-ppas-in-ubuntu.61390">Adding PPAs in Ubuntu</a>

Whatay great tool. Using on my system and battery life has surely improved. I however have tweaked /etc/default/tlp conf file manually for some parameters.
