Dell TB16 & XPS 9560

I just got both 3 weeks ago and the fan on the dock seems to ramp up all of a sudden and the power cable does not ligt up . I have to unplug the dock and remove all the connections and reboot then the fan stops and the power is restored .I only have a keyboard and a usb interface plugged in the dock .

When i shut down at night i keep everything plugged int the dock . In the morning I wake up to a loud fan and the power is no longet going the pc . I have uodated EVERYTHING bios etc .... 

I would like some assistance from Dell please ...  for the price i paid i could have got a MAC ...

Amost there
