Thanks to everyone for your posts and detailed information. Im quite sure it was not a mechanical/non connecting issue... it was the brick drawing the full wattage as my laptop was at 2% battery. Do the airline give you details as to what the maximum wattage they provide...? I guess I will buy a travel charger for air travel, should I look for something thats below 100W or do I need to go lower to the 70W range to be extra sure...?

Thanks again.
