The laptop will have small DC-to-DC converters and/or regulators to
develop the needed voltages. With 19-VDC from the wall-wart they've
got plenty of "headroom" to run their regulators. Note that there are
other voltages running around in there to power the CPU, which uses
something around 2.2-VDC I think.

19V to 2.2V is one hell of a drop!
