I have been trying with the third Surface Pro 3. The type cover appears to wake up the computer only when pulled all the way before flipping it to the back of the computer. Can you try this, Rlarsen462? Please let me know if it works.
What's the big deal about the cover waking up the device? Just open the thing and if the screen doesn't turn on, press a button on the KB or the touchpad. This is ridiculous. Mine doesn't wake up the screen but who cares?
