HP ZBook Power Mode Monitor

On some HP ZBook models the battery/AC change power_supply event is not trigerred at all and TLP won't automatically change the power modes from battery to AC and vice-versa resulting in either low perf mode on AC or consuming too much power on battery.

To fix this, I've added a systemd timer to poll for battery status changes and trigger udev events on power supply changes.

Contents:

  • systemd timer
  • systemd service that is executed by the timer
  • shell script that is executed by the systemd service

Usage

Install: sudo make install Uninstall: sudo make uninstall Enable/start: sudo make enable Stop/disable: sudo make disable

The events are logged in the systemd service output and can be retrieved via usual means (journalctl).

The state file that is used for storing the previous (last seen) state is stored under /var/run. When the current power supply state is different from the stored state, an UDEV event is triggered and other services can be informed.
