Hello everyone, merry christmas to you all! can I get some insight to this please.. A few issues, creaking and smudges! The other day, I was playing a film, and when the film started it displays a completely black screen, no dead pixels great! however... ...I can see what appears to be about 5 permanent smudge lines, two about 3 inches in length and the others about 1 inch. I haven't ever touched the screen and these marks must be in the screen which i find very very odd... I have tried to clean the screen and got the whole thing looking completely immaculate, but these smudge marks do not move. When the screen is off you cannot see anything that would look like it would be causing it. however when you switch it on and turn the brightness up and are looking at a black/grey area you can see them, and you know how once you notice something it eats away at you... this must be a manufacturing error?!. I have 3 years apple care, and the laptop is about 25 days old bought from apple online. very upset about this, and whats annoying is, they are not very noticeable marks using the MBA for day to day things but when you watch a film etc you just can't help but to notice them.. so its forcing me to take action reallly disappointing. To further this frustration i swapped out the first MBA i got as the right speaker was faulty.. this was fine at the time as it was within 14 days old, but now it looks like all i can do is to take it to an apple store and pray that they can fix the smudge and creaking issues. I guess they will have to replace my screen only? just need a bit of support and advice on this really. many thanks for reading > photo sorry its so small, but can you see those smudge lines, they appear darker than the rest of the display on top of this I noticed my 2011 13" MBA creaking around the track pad area and can get rather annoying, especially as it makes it feel cheap! anyway, from what i have read (linking me to this forum) its a rather common problem and you need a pentalobe screw driver or something?! I have booked it into the genius bar and i am going to ask them to re-seat it for me on tuesday.
