I just bought a used blackberry 9780 with this problem; I found it was caused by the battery not having sufficient connectivity to the blackberry. It worked when I pushed and held the battery upwards against the phone's connectors. My response is a bit dated here but anyone finding this answer might want to try this and if it's the case, find some way to keep the battery more firmly against the connectors.
