Restart TLP service without rebooting system

  • 772

TLP helps make my laptop more conservative on power when on battery power, and more performance focused when on AC. The issue is that when I want to enable/disable TLP or change some settings with TLPUI, it requires a reboot before it takes affect. I've tried sudo systemctl stop TLP and sudo systemctl start TLP, but this doesn't seem to have any effect.

    For changing settings without restarting, you should be able to (re)start the service with.

    From https://linrunner.de/tlp/settings/introduction.html#making-changes:

    sudo tlp start

    For changing the charge thresholds without restarting you can use the tlp setcharge command. It sets the charge thresholds immediately, using your settings if you don't supply any other arguments. On reboot, your settings are reapplied when TLP starts.

    From https://linrunner.de/tlp/usage/tlp.html#battery-features:

    sudo tlp setcharge [ START_THRESH STOP_THRESH [ BAT0 | BAT1 ] ]

    Sets the thresholds to the given values. ... Without parameters the configured settings for the main battery (BAT0) are applied. Upon reboot, thresholds are reset to the configured settings.
