Some help with a wierd docking station problem

Hello there! i've got an issue with my docking station. When i connect with the station it works fine. But when i disconnect it from electricity and reconnect it, it doesn't recognize anything. it doesn't load my laptop, my screens don't get a signal and the light on the station doesn't change coulour.

i've got some other docking's where it works fine.

i've managed to get them working again after the disconnect. By disconnecting them again, unplugging one of the screens, cconnecting it to electricity again and then it works. And it also works with the second screen when i reconnect it while it's working with one screen.

Its a 40AY, it has the latest firmware 3.0.85, it does the same with multiple laptops.

If any of you have any idea how to fix this i would be a great help.
