Overheating issues in laptops are a common issue. And since summer is here, using laptop in your lap will literally burn your balls (intended to male readers). I have used Jupiter to fix overheating issue in Ubuntu 12.10 and older versions. Jupiter was a real gem of an applet. Install it and set it to power saving mode and you could feel the magic. No blurring of fan, no burning sensation between your legs (this time intended for female readers, if there are any) as long as Jupiter was there holding the castle.
Jupiter is dead, any alternate to Jupiter?
But since the development of Jupiter has been stopped, the heat is on again. Earlier Ubuntu version can still use Jupiter but it is no longer supported starting Ubuntu 13.04 Raring Ringtail. The PPA from Webupd8 does not work any longer. And this is why I was looking for a suitable program that could fill the void left by Jupiter.
During my search, I read some discussions about a command line tool TLP that could be used as an alternate to Jupiter in Ubuntu 14.04 and Ubuntu 15.10.
Update: You can now install Jupiter in Ubuntu 13.04 and Linux Mint 1 (not recommended to use Jupiter)
Install TLP to solve overheating in Ubuntu 14.04 and 15.10:
The same steps are applicable to other Ubuntu based Linux distributions such as Linux Mint 17 and elementary OS Freya.
Open terminal (Ctrl+Alt+T) and use the following commands to install TLP:
sudo add-apt-repository ppa:linrunner/tlp sudo apt-get update sudo apt-get install tlp tlp-rdw
You can use the following command to uninstall TLP, in case you don’t want to use it anymore:
sudo apt-get remove tlp sudo add-apt-repository --remove
How to use TLP to get better battery life:
Once you have installed TLP, it will be automatically started from next reboot. Though you can force start it right after the installation, without restarting, by using ‘sudo tlp start’ command. And afterwards you need to do, basically nothing. It is a full-fledged command line tool with lots of configuration option but you don’t really need to it. Install it and forget it. It will be doing its work in the background.
Does TLP really solve overheating and increases battery life?
Answer is subjected to user experience and vary according to what I have read in discussion. As far as my experience goes, it does reduce the temperature a bit and the blurring of fan occurs less frequently but it is not the same experience as Jupiter. I did not see any significant improvement in battery performance though. As we don’t have any other option, we have to take TLP as an alternate to Jupiter to solve overheating in Ubuntu 14.04. Apart from that you can also follow best practices to improve laptop battery life.
