I received my new AC adapter in the mail. It didn’t fix the problem that I am having.
I called Dell technical service (I have a maintenance contract), and spent about 1-1/2 hours on the phone with a lovely young woman in New Delhi. We came to the conclusion that my battery is okay, but either my power port or main board is bad, so we scheduled a technician, who is supposed to be here sometime before noon on Thursday to replace the main board.
The young woman, Thanglen, and I also discussed our feelings about the Coronavirus and the resulting chaos in the world. She said that we can only do what we can, that we all have a time that we will go, and that it is in God’s hands. I agreed with her.
I now have a Bluetooth keyboard that works with both my Kindle Fire and my Android phone, so I can use those devices to access the internet, if necessary, but it is still not idea.
Thanks to rhea for the suggestion about the keyboard!
