This just happened to me. Left it connected overnight and woke up to white screen and, when I disconnected, dead battery and shutdown. Reconnected and it showed connected but the battery icon stayed white and the Fuze didn’t show up in Windows Explorer.
It was the cord.
I tried it with a different cord, and it’s charging and connecting just fine now. Even a cord you’ve used regularly can just stop working. (This was a generic, by the way, that I’ve been using for months.)
