I have a problem about the condition of battery in Ubuntu, although the usage of resource system is better than Windows, but the battery is faster to lost. I tried to install TLP instead jupiter that discontinued.

start tlp on terminal
start tlp on terminal

  1. Open terminal console
  2. Run this command to add the repository:
    sudo add-apt-repository ppa:linrunner/tlp.
  3. Run sudo apt-get update to make your computer aware of the new repository.
  4. If there is error about

    “Could not open lock file /var/lib/dpkg/lock – open (13: Permission denied)”

    you can solve this  by run command

    sudo rm /var/lib/apt/lists/lock
    sudo rm /var/cache/apt/archives/lock
    sudo apt-get update
  5. Run sudo apt-get install tlp tlp-rdw to install TLP.
  6. If you are on a ThinkPad, you’ll need to install a few more packages for maximum battery life, which you can do with the command sudo apt-get install tp-smapi-dkms acpi-call-tools.
  7. Finally, run sudo tlp start to start the TLP service. You won’t need to do this ever again as it should start automatically on each boot.
