Then there's but one thing left to do.
I thought about it, but I'm glad I did not. I tried everything Google suggested, but it was to no avail. I gave it another week, and when I got home from Perry's, I plugged it in, and voilà, it is working fine. So now I have two. I like them both, so I am going to keep one in the den and one in my bedroom. Problem solved, and it worked out pretty good. Maybe if I keep it charged up and not use it on just battery, it will stick it out a little longer. Or it could go next time I pick it up.
