Waves,
You are a helpful genius!
When I mentioned "power supply" to hubby he said that my computer might not like the 15 minute backup battery that I have it plugged into.
. . taking a chance on power surge stories I have heard.
My computer is fine it seems.

Next I will unplug from the wall and into a power surge protector . . . leaving the battery out of the picture entirely.
Thanks.
I'm checking in off and on but I gotta go and get some other things done tonight.
I walked .6 miles. That helped my mood. I feel alert. .. .probably should get some hard paper work done during this time window.
