I havent been on these forums that long but im starting to notice a pattern of muppets buying an AW, having it faulty and then moaning and saying 'oh i want my money back please and you can have a faulty laptop back because i dont want it now'.
I had my 7700 just a few weeks back. When it arrived there was a HUGE section of bad paint so i called their tech support guys. All they asked was for a photo of the damage and then they ordered me a new lid for my 7700. They've also let me keep my laptop while i wait for the new part, and once it arrives they'll only have my laptop away for a few days.
At the end of the day once you agree to purchase something from anyone you enter a contract. I'm sure by using the term 'MAY BE' on the agreement they implied that if its a seriously crazy major unfixable problem then they will give you your cash back 100% with no problems. If however its a dodgy fan it seems totally out of order to ask for a full refund. Send the thing back and get it fixed. Im sure you can survive without you laptop for a few days, or even a week!
If you look at the number of components that make up a laptop i'm sure the odds of something failing are around 100/1. Now if AW gave a full refund to everyone who had a dodgy laptop on arrival then the price of all their systems would be astronomical and nobody would buy them! Stop your moaning. Get it fixed or pay the 15% fee. You entered a contract and AW stated they might give you a full refund. They've said they wont so its tough shite.
PS. How do you know it didn't become damaged in transit after the AW checks? Despite the great packaging all it takes is one lazy posty to ruin your system.
PPS. Anyone thinking about buying an AW please dont hesitate! Every time i've dealt with AW customer services and tech support they've been very helpful and very understanding of the fact that i spent a lot of cash on a system and have always bent over backwards to help me.
