Thanks to everyone for their input on this issue. I received my new battery today, installed it, and bingo. My camera is alive and well.
As to the watch battery inside. Before I had the good sense to ask the Community about this issue, I looked on youtube. Many people there talked about the battery inside as being the issue.
At any rate, thanks again to the sound advice I have received on this site. My camera is operational and I look forward to using it.
