230w laptop supply???
most lappy supplies are 60-90w wireless transfer (20-40% anyway)  looking at them online, clearly the laptop still gets 60-90w and the rest goes "into the ether" just so you dont need a cable!!! **but you do, because the charger needs mains - so what's the fucking point!!!!!!!
