3. Systemd Service

A systemd service and timer is installed by ZenWatt to apply the power limits again after a system reboot. Clicking the Enable button in GUI will enable the timer.

To avoid conflict with other power management tools, following services will be disabled if they are found on the system.

• GNOME power-profiles-daemon - power-profiles-daemon.service

• CPUPower - cpupower.service

Disable the ZenWatt service from the GUI to re-enable the GNOME power-profiles-daemon.

3.1. TLP

ZenWatt is compatible with TLP. Settings selected from ZenWatt’s GUI will also be applied to TLP.

Tip

If you don’t wish to control the CPU governor or EPP profile using ZenWatt, set the option to ‘auto’ from the GUI.

Read the following article on how to prevent conflict between TLP and other power management tools.
