Right again, of course. I was thinking along the lines of a minimum
expected current, to protect the adapter from overload, or a maximum
current, to protect the laptop. But, as you wrote, if the adapter
wasn't powerful enough it would just work at max capacity and the
laptop would use the battery for the rest. I still think overcurrent
protection could be useful though?

I'm glad I don't design power supplies for a living. ;) I'm not a
star at analog electronics but I'm learning.
