Sigh . . . I finally disabled power service in msconfig.
I am working on some stuff that requires physically checking some data against other, so went into the living room and checked. I came back into the "office" and my computer was asleep! I tapped the space bar on the keyboard and she woke up!
OK, so some power saved and a few buckets of coal no longer dirtying up the environment on my account.
At first I noticed that my mouse was a bit jiggly, but that smoothed out and no longer seems to be a problem. I guess he was just settling into his new surroundings.
