And why do you believe Apple after 3 years?
The problem is the GPU. Nothing else can be causing the problems that are occurring other than that.
Well, actually,isn't the unofficial explanation from Apple something like solder expansion where the GPU connects to the logic board?
Fair enough. Then why are those getting logic boards replaced having the same problem occurring wth a very short time frame of the replacement?
I'll spare you the details but I had this exact same symptoms that many others had. It started with my first split screen and freeze and then went downhill from there in a few short weeks to the point where one morning no matter what I tried and how reboots and startups, nothing worked. At best I got the gray screen after the apple/gear churning screen. At worst, I got a royal blue or even black screen, or even nothing at all.
I applied a "fix" that same morning, staying entirely within Apple's policies and guidelines, and my early 2011 mbp has been working perhaps better than ever without a single symptom. Even clicking the checkbox for Auto GPU Switching in Energy Saver works every time, whereas prior to the fix clicking on that box was instant freeze.
I always thought Apple's explanation was fishy since I first started researching the problem. It just didn't make sense to me. Kinda' like close but no cigar.
I have to believe Apple never had a frickin' clue what the problem was and that's why for the most part they've remained mum for several years, maybe hoping the situation would just die off.
Being that Apple is a capitalist corp, earlier this week I emailed Tim Cook at Apple offering him a proposal if I could demonstrate where this problem wasn't and approximately where it was.
Jessica Hogue, an Executive Customer Relations type gal contacted me and after several days of playing phone tag, having never actually read my email, insisted I freely give her my information for a potential fix and I said I'd be happy to when Apple agrees to my proposal. Jessica said, they don't do that, and again, Jessica insisted I freely share my info with her. It seems that Apple wants me to play socialist while they play capitalist. Jessica said, if I change my mind, please contact her and I said likewise.
Even if my early 2011 mbp goes belly up tonight, I've already been shown that their explanation cannot be accurate and that they completely misdiagnosed this problem and potential solution. Sure the boards may have issues with bad soldering, etc. and may indirectly contribute to this problem, but there simply is no way that this is the problem.
And if I'm right, that could more easily explain why Apple has done so little in their attempt to rectify the siuation and calm a good percentage of their mbp user base.
At the very least nobody in their right mind should continue to believe anything Apple has to say about this longstanding, serious, and expensive issue that has turned so many mbp's into worthless bricks.
