Hi, still no solution! They asked me to pay 800 CAD to be given a refurbished SB which would be another mistake because these kind of errors can be caused to your new refurbished device too. With that money I would buy another laptop which last after some stupid updates.
Hmm I was afraid it would be like that, very annoying, very Microsoft. Replacing it with the same without finding the problem would not be wise indeed. Maybe we have to get used to the Apple stuff after all :-( Thanks for your reply anyways.
