Yes, it happened to me. I have read reports of sudden shutdown syndrome in macbooks and now it happened to me. I don't understand why this happens. It only works when its connected to power, otherwise it shuts down in about 5 minutes. Now my battery shows 0% even though it has been connected to power for about 15 minutes. Any help will be greatly appreciated. P.S. I'm guessing it has to do with the battery?
