Ed Mourbey, the very first thing I would do , is to change the battery. It is most likely at the end of its lifecycle. Replace it and reevaluate. Also, clean the $$&# connector of any debris, check for broken, bend or corroded pins. You might even try a new cable. I am certain that a new battery will resolve this issue. Here is the guide and the battery is available right here. Hope this helps, good luck.
