Today's laptops stop charging when the battery is at 100%. At least
that is what the indicators show.

all battery operated products stop charging when the battery is fully
charged.

otherwise, bad things happen, like fires and explosions, and customers
don't like that very much.

That'd why some UK airlines do not allow laptops and some mobile
telephones in cabin luggage.

you mean in checked bags put into the cargo hold (and that ruling may
change).

batteries are allowed in the cabin, where any fire would immediately be
noticed and extinguished via any of the several fire extinguishers on
board by the flight crew trained in using them.
