It seems the internal battery had died and it was no longer revivable . True to personality , I went to the manufacturer 's website and initiated a live chat with a support representative . I could n't tell if I was chatting with a person or a computer and kept asking if I was really chatting with a person . He kept assuring me that he was human , but he could n't explain why he was giving me information that had nothing to do with what I was actually asking him about .
