Hi. How does the battery charging disable function works in the alienware laptops? Does it mean the battery won't be charged and draws power from the AC supply?

Probably. The issue is that charging wastes energy and generates heat, so if you have an auxiliary battery pack or say you are running from a car battery, you don't want to be charging things. Or if want maximum performance without extra overheating by simultaneously charging.

If the laptop is drawing current from AC then when the charger is switched off will the laptop turn off?

What do you mean by charger is switched off? - If you still mean the disable charging option then no, the laptop should run, just without charging.

If you mean the physical switch that some power bricks have to turn off A/C then yes, it will run out of power eventually.

Best thing is to try it out as an experiment.
