Correct.  The "doesn't shutdown on AC removal with main CPU offline"
behaviour is very new.  No IBM ThinkPads have it.

I don't know which Lenovo ThinkPads don't, though.

It *does* mean you need to unplug AC and remove battery if you ever hit EC
issues that get it into a bad state on the new Lenovo ThinkPads.
