One thing I did discover is that the issue is hardware dependent. I
have an older Dell laptop and it suspends when I close the lid. It's my
newer laptop, i.e. about 4 years old that is currently having the problem.
Here's the cpuinfo for the working system

Thanks for the information, but I don't think this is the problem since I
don't see those messages. What I discovered by using gnome-tweak-tool is
that the default behavior is to not suspend on lid closed.
"Don't suspend on lid close" is Off by default. This is a double
negative so it means suspend on lid close is the default. I'd rather
it follow the language for Power Button which is to use an Action
pop-up menu. Seems like there are three sane possibilities: Nothing,
Suspend, Hybrid with the default being suspend.
What's really
confusing is that the entry under the Power section of gnome-tweak-tool says
"Don't suspend on lid closed" and there's this slider to the right, which is
unlabeled, so I don't know what state it's in.
Weird, sounds like a font related bug or something; that slider for me
is an Off / On slider and by default is Off (slider is to the left).
