Hello there, I am pretty gutted. Today I noticed that my MBA screen was more wobbly than usual. I did not think much of it until I tried to close the lid (which is not often throughout the day). Anyway, when I did, I couldn't. Something about the hinge was preventing me from doing so. I applied light pressure when closing it as you do and 'crack' (gasps) - anyway, a small crack appeared slightly to the right of the left hinge (just on that central strip thing, about a CM long). This is now preventing me from closing the lid. I probably could, but fear that I may make it (the crack) worse. The left hinge itself actually now appears to be higher than the right 1 when looking at it dead on and from the side also. This is probably what is preventing it from shutting. What's worse is that transporting it now will be challenge without it being closed. I shelled out for the AppleCare in January - but my first reaction is that it will not cover it. I will be particularly frustrated if that is the case - as this is genuinely not my mistake - I have not dropped or banged it for example. I have no idea how it has happened. Has anyone experienced a similar problem? How did you resolve the issue? What cost dare I say do you think I would be looking at if the AppleCare does not cover it. Any help would be very much appreciated. Really am baffled how this might have happened (I am so careful with it - its like another child to me!). P.S - it is a Rev B MBA purchased early 2009 - Applecare till early 2011 - I have an Apple Store in my home town Newcastle, UK.
