Hi All, I too am having a problem charging my tab. I am running it off the OEM wall unit and when the tab is plugged in to it a white lightning bolt over the battery is displayed. Also, the screen reports that tab is charging.If I plug the tab into my PC's USB port the lightning bolt is replaced with a red cross and no charging message is displayed. Using the wall unit and despite the "charging (AC)..." message the unit does not charge. Based on the UI I am assuming that the cable and the wall unit are functioning correctly which leaves me thinking it is the battery. Is that reasonable? I have done a factory reset but that did not help. Any thoughts, helpful suggestions gratefully received.
