So Orville has returned home from the computer shop. They said they basically had no idea what was wrong but had tried this and that and the other thing and finally the computer was working again.
I took him home, and plugged him in, and pressed the button, and … nothing. Didn’t work.
So Michael called the shop and told them this, and Computer Guru Jamie, who owns and runs the place, came over to our house to investigate. (It helps that Computer Guru Jamie is a good friend of Michael’s.) He tried this and that and the other thing and got Orville running again. He thinks the problem is the motherboard won’t hold a charge or something and if it recurs, a replacement will be necessary.
But for now, Orville is back.
