That is just unfortunate. I know that is was tricky to to get them to accept my replacement unit, but there was no way that I was going to go through reinstalling everything only to be stuck with a worse machine. Fortunately, the first level support guy was understanding and was willing to try and figure it out. I still spent over 1.5 hours on the phone and he had to consult several people. Unfortunately, the follow up with "Daniel" (my "friendly" neighborhood Surface Care Team member) was far less productive. After over a month of a pointless back and forth (during which he went "dark" for two weeks) I finally demanded that the replacement be from a newer lot and that I could immediately send back any device that did not meet my expectations (since a NEW replacement was a non starter). Well, Daniel was never heard from again. I have since decided to just live with (for the time being) my issues as my SP2 is actually quite stable aside from the battery weirdness, and the whole ordeal was just getting too frustrating. I really don't want to get stuck with something worse - and since I have the extended warranty, I can always pursue a replacement later. I sincerely hope that it works out for you.
