Dear linux geeks,
In this tutorial I will show you how to save power and improve your battery life in your Ubuntu laptop.
How does it work?
The main idea behind this power saving solution is the reduction of hard drive spins. Less hard drive spins, less consumed energy, better battery life.
The Laptop Mode will helps us to achieve our goal. In order to save power and make our laptop battery last we need to make our disk write activity “bursty”. What does it mean?
It means that only reads of uncached data will cause a disk spinup.
Ok ubuntu geeks, let’s do it.
Open a new terminal(CTRL+ALT+T)and run the following commands to install a nice and simple GUI tool that lets you toggle individual power saving modules.
sudo add-apt-repository ppa:webupd8team/unstable sudo apt-get update sudo apt-get install laptop-mode-tools
After the installation is finished, run the following command to launch the configuration tool.
gksu lmt-config-gui
Now you can play with the configuration files. What about the Laptop Mode, how do you enable it? Don’t worry! Once the installation of the configuration tool is finished the Laptop Mode should be enabled by default.
