Thanks to all who replied, esp. David A. Harding for his great log
suggestions (which I haven't gotten around to really diving into).
I *think* I found the problem, and a work-around. But I don't
understand it or how to fix it (short of rebooting, which I'm pretty
sure will work).
It seems that some part of the machine thinks it's on battery power when
it's really on AC, and vice versa. I have the Gnome power manager set
to suspend never on AC and after 15 minutes idle on battery, but I have
determined that the OPPOSITE is happening. That is, I am not suspending
when on battery but I am on AC. So naturally the work-around was to
tell it to never suspend on battery either.
The kicker is that the Gnome Power manager notifier correctly tells me
when I am on AC or battery! So something is backwards, but I have no
idea what or how to really fix it other than rebooting, which I did
finally do and which did fix the problem. :-/
Later,
JP

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
