Improve battery life/performance on Ubuntu with TLP

TLP is a very nifty piece of software to improve battery life on Linux laptops, and it comes with external kernel modules for Lenovo ThinkPad’s which further improve battery life.

sudo add-apt-repository ppa:linrunner/tlp

sudo apt update

sudo apt install tlp tlp-rdw

If you are running a ThinkPad, you can install the following:

sudo apt install acpi-call-dkms

Start TLP with the following:

sudo systemctl start tlp

Enable TLP to autostart on reboot:

sudo systemctl enable tlp.service

Finally, reboot your laptop for settings to take effect
