At an estimate your laptop uses 50W.
You need to use a resistor that dissipates a similar amount of power as your laptop.
Testing a SMPs at less than one tenth of the power you're intending to draw is a waste of time. Your switching regulator might be 84% efficient at 3.12W but at 50W it might only be 50% efficient.
