If I forget to put my phone on the charger overnight and the battery fully discharges, I plug the AC adapter in and nothing happens, It will not charge. The green LED light comes on but will not charge the battery. After 3-4 hours , Nothing. After reading many posts I took a USB cord, stripped the end and used the positive and negitive wires to charge the battery for 2 minutes put the battery back in, plug the ac adapter in and "Viola" it then charges. I just got a brand new battery from verizon but it happened again. What could the problem be? Sorry, Should have put this in tech issues!
