I've got exactly the same problem, even when I plug it into the AC adapter. When I plug it in the AC it starts-up, but gives me the information that there's unkown battery left? How could this happen, I've used the thing with a new battery for about 4 days and then I let it rest for about 4 weeks but now it's dead!
