My Omega2+ won't boot. When I connect my Omega and expansion dock it to my computer, they both light up in around 20 seconds, and then all light on the boards turns off, and nothing else happens. I can't connect to it with a serial connection, I don't work. Wifi doesn't turn on ether, so I can't connect to it like that. What should I do?

Helle, do there follow a power duck in the box when you buy the omega 2+ for 9$. And do you need to buy a expansion dock, in order to use the arduino dock.
