Placed my X2 on the charger. After three hours noticed that it was not charging. What I did notice was that the LED light would turn green, then go off and the Motorola red symbol would appear with the Dual Core Technology screen label. Then it would go off and the Green LED light would reappear. Then go off and the Motorola Red Symbol would appear. It was in some sort of loop. Meanwhile, the charging would not occur. I called Asurion and they are sending out a replacement. My question is what is this? and is there a fix? Or was getting a replacement the best idea? Also, is this a well known defect or just the luck of the draw for me this time? I did pull the battery and re-install. Same thing occurred. Then I eventually turned on the phone and placed it on the charger again. With the phone "turned on" it charged overnight. Luckily I can still have the phone and use it today. Still getting a replacement today as it was ordered. But still wondering if this has occurred to anyone else and what is the fix?
