I charged my camera for 6 hours but it won’t turn on.
Be sure that you have used the wall adapter, ION Battery Booster or a high speed USB 2.0 port to charge the camera. The camera will not charge properly on a USB 1.1 port. A USB hub with many connections may not properly charge the camera either. A camera that is turned off and then connected for charging will have a bright red LED. The LED will change to a dull red flash when the camera has finished charging.
