Sorry, but that's not the way Georg Simon Ohm explained how currents flow;
the 4.5A/72W rating describes the maximum ability of the adapter to
deliver current and power within its designed safe temperature limits.
If a TP600X is designed to operate with a 16V, 3.36A supply then a 16V,
4.5A supply from say a T21 will work perfectly well, safely below its full
capabilities, and the computer will never notice or draw any more power.
