Dear Tim Cook, As your office is likely well-aware by now, thousands of Apple customers using your 2011 Macbook Pro line of computers are experiencing widespread GPU failures, including myself. Two years of normal use is a completely unacceptable amount of time for a big-ticket and supposedly high-quality machine to be experiencing such failures. Many forum posters believe that lead-free solder which is environmentally friendly but makes for weaker connections is the source of the problem. (Improper use of lead-free solder is blamed for the Xbox 360s red ring of death issue, which caused a substantial number of unit failures.) This is what I believed first too. Untill I saw this video: https://youtube/watch?v=1AcEt073Uds A re-baller by trade explains that reballing will not permanently fix the problem as broken solder balls are not the cause of the problemn. It is more likely that the bumps in the underfill are the real problem. They no longer properly connect the die to the substrate. This can indeed be easily tested by heating the GPU to such a temperature that the solder will not yet melt. This can be done by giving a towelie or sleave treatment (closing the lid and putting the machine in a sleeve when GPU failure occurs). This will nog heat up the machine sufficiently to melt any solder, but it will still temporarily revive the GPU. https://discussions.apple/message/26850345#26850345 The real cause seems to be a combination of factors that lead to GPU fail: Insufficient cooling of the chips due to design error. The air intake is too small to supply enough air to the cooling system; Low quality cooling paste used. It dries out too quickly; Too much cooling paste used; Heat-pipe plate surfaces are quite rough (not lapped); Constant switching between the integrated and the discrete graphics chips causing the GPU to heat up and cool down frequently, wearing it out; It is abundantly clear that this is a design / manufacturing issue. Apple needs to address this. The forum thread on this issue (https://discussions.apple/thread/4766577?tstart=0) has 1.632.126 Views and 9,090 replies. Thats right. One point six million views. Thousands of people have this issue. Thats thousands of hard working designers that paid top dolar for a PRO machine. All being left out in the cold now. Unable to provide for their families. Please start a replacement / trade-in / trade-up program to help these people. I have added my name to the growing list of support forms, and petitions, registered feedback through the official form, created a case with AppleCare, and now am contacting your office directly to urge your for a public response on this issue. The people will not be satisfied until our machines are restored to full working order under a replacement program. Restoring machines using refurbished logic boards will only perpetuate this problem, which is well documented in the support communities.
