If you have access to another monitor, try connecting your laptop to that monitor to see if the issue persists. This can help determine whether the problem is with the laptop or the docking station.
Go to your laptop's power settings and check the display settings to ensure they are set as desired when on battery power.
Ensure that the docking station's firmware and drivers are up to date. Check the manufacturer's website for any available updates or support information.
You may also try resetting docking station.
