Hey guys,
Don't really know if this thread is still active, but I sure hope so. I'm writing from the Netherlands, and I too have the blue screen problem. I own a mid 2011 MacBook Pro 15 inch, bought somewhere in June 2011. After reading every single post in this thread I would like to keep you guys updated on my progress. So, here is my story:
I can't recall when exactly the problems started. Inconsistently, but always after using CMD+Q I would get a frozen lightblue screen. I quickly realized that it was just the screen, since the F10 and F11 (volume) buttons gave their confirming sounds. Also could I still change brightness. At first I ignored the problem but eventually it got impossible to ignore, occuring with an average of three times a day. Then I decided to search the internet. Sadly, in the near end of 2011, I couldn't find anything(not even this thread 😕).
After a while I decided to go to the Apple retailer where I bought my computer. I would like to point out that this is not an official Apple store. They heard me out and claimed they had never heard of this problem before. Also they found me unreliable since I could not recreate the problem in front of their own eyes. I didn't know then how to force the error. They sent me home with the assignment of re-installing OSX Snow Leopard, updating all of the applications and told me not to install any third party apps. All of this I did, and as you can guess, the problem wasn't resolved. So back I went, this time they took in my computer and gave it a "stress-test", which pointed out that I wasn't in fact as unreliable as they thought and they acknowledged the problem. After about a week I could come back to pick up my laptop, and as it turned out, they replaced my display - because that was what HAD TO BE causing the problem. Not.
So, without any progress, I returned to the store. They took in my laptop again, redid the stress-test and found the same problem, surprisingly. They concluded that there was a problem with the videocard, and since all MacBook videocards are welded on to the motherboard, they replaced my entire motherboard - or as you might say: LogicBoard. Now, this all took place about three months ago. And here I am today, writing to you, with a still unsolved problem.
Since the replacement of the motherboard I have had a total of four freezes, all after CMD+Q. Considering that a motherboard replacement is quite hardcore, I think it's safe to say that this confirms your assumption of the problem not having to do with the hardware.
Tuesday I am going to go back to the store, and tell them the problem still exists. I am consciously not going to tell them about what I learned from this forum (videocard switching etc.) out of fear they will just give me the blame of the error. I am seriously expecting them to at least give me a free OSX Lion upgrade, and if not give me a new device. The new one naturally not being from the mid/late 2011 batch.
I will keep you all updated!
Thanks for reading,
Roks
EDIT: I would like to add to all of this that I have encountered something new that might possibly be related to the problem. Whenever I start up a game (Diablo III) the screen gives a quick blue flash, in exactly the same colour as when it freezes. Although this time, it's a flash and nothing permanent. Anybody any clues?
