When I connect my Samsung Galaxy Camera (EK-GC110) to either an external power source (AC charger) or to the computer, I get a "battery disconnected" error message if the camera is powered on, or if it's off, a yellow triangle with a battery icon with a slash through it. The battery is, obviously, NOT disconnected, as it's powering the camera. And when it's on, I can see the available battery percentage. But it also shows "not charging." I can charge the batteries in an external charger if I remove them from the camera, but not when they're in the camera. What might the problem be? I've tried power-cycling, removing and re-inserting the batteries, different cables and chargers, but to no avail.
