Used this guide to replace my battery. Sadly, it didn't fix the problem. The problem is with my charger connection. It is loose. I had hoped changing the battery and looking at the problem from the inside would resolve it. The charging connection is in it's own little housing. I considered opening the housing but I had no replacement parts to fix whatever may be wrong. I greatly appreciate the quality of this repair guide. There were no problems with tear down or putting back together. Thanks again!
