Let's here what you got.
I had the same issue with my i5/256/dgpu. I let it charge a little, kept it plugged in, then hit the power icon on the screen and chose restart. Then I got the menu for setting language, etc. I'm going through that setup now.So I received my i7, 512gb, 16gb Ram Surface Book this morning but am unable to connect to wifi. In fact at the login screen all I have is an icon showing the Ethernet is not connected. I can't even select a wifi network for some reason.
The battery is completely dead so I'm charging but I don't see how that will change anything.
Am I missing something?
