Many who use notebooks have an “infinite war” (seriously, no pun intended =)) when trying to save as much battery as possible, so they can use the notebook for longer. The tool we will use is called TLP.
TLP is a tool via text line that allows you to control kernel modules and adjust device consumption in an individual and very detailed way, however, like any application that you will be using via terminal, a certain technical knowledge is necessary, which can be drastically reduced with its interface.
An interface to TLP
In Windows it is less common to happen, but in the Linux world the software and the interface for it are not necessarily the same thing, in fact, it is possible, in some cases, to use several different interfaces for the same software.
It’s the TLPUI is a graphical interface for TLP and allows you to manage TLP in a simpler and easier way. We did a very complete article explaining how TLP works.
Both TLP and its interface are distributed to Ubuntu and Linux Mint through a PPA repository, and as you may know, it is possible to add PPAs without using the terminal, however, for the purposes of versatility we will use it here in this tutorial .
First we will install TLP and then install TLPUI. Let’s open the terminal and type the following commands:
sudo add-apt-repository ppa:linrunner/tlp -y && sudo apt update && sudo apt install tlp tlp-rdw -y
That done, just wait for the process to finish and add the following commands in the terminal:
sudo add-apt-repository ppa:linuxuprising/apps -y && sudo apt update && sudo apt install tlpui -y
Once installed it is very simple to find TLPUI, just access the menu and type «tlpui» and the following program window will appear.
This facility is very welcome, especially for those who are not familiar with the terminal and want to do energy management, TLPUI comes to help and a lot of these people, since the change can be made in a click or two, facilitating the their lives.
How to use?
On the first screen we can have an overview of what TLP does, how to enable and disable, which standard mode we want (battery or ac, which would be plugged into the outlet).
Another interesting tab is “Disk”, where we can better configure how our HD will behave in each situation (via battery or not). Remember to take care when enabling / disabling each option, do so very carefully, as this will affect the way your machine will work in some circumstances.
The «Network» tab, we can configure how the Wi-Fi will behave, since the Wi-Fi connected together with the bluetooth (when available) is one of the biggest energy consumers when not used, together with a great brightness of the screen . So in this tab we can configure this.
Another interesting tab is that you can configure the “USB”, where we can configure how the USB ports will behave when we have a device connected, such as a Smartphone, or when we have a printer plugged in and the like
To learn more about each function of the TLP, visit their website, there you will find very detailed documentation.
What did you think of the tip? Have you ever felt the difference?
See you next time, big hug.
