Well I've found a reseller that was willing to send it back on my behalf.
It's been sent to them, just waiting for it to be "repaired", apparently they actually swap the B2 chip for a B3 rather than exchange for a B3 model.
Then I will just have to wait to hear what it's going to cost for them to deal with it on my behalf, I would expect a minimum of return Carriage.
I dont think you are responsible for any charge, ASUS fix it and send the bill to intel (including p+p)
