Because of humidity the connections between GPU and video memory chips (that are located inside of the motherboard) get corroded and the replacement of GPU won’t help. This solution works in about 90% of cases because the problem may be not in the video chip itself but rather in the area of the motherboard under the video chip.
We offer to replace the video chip (GPU) with a new one and at the same time we also do an ultrasonic cleaning of the entire motherboard so the computer will look and run like new for many more years. Nowadays Apple refuses to repair these computers because they are considered “vintage” and many people are forced to invest in a new computer.īut we say “NO” to environmental pollution and have two solutions to resolve the GPU issues in MacBook pro model A1297 (17”), A1286 (15”) in 2011-2012 models. A MacBook restarts while loading Operating SystemĪpple had a recall for this issue by replacing the whole motherboard but the recall ended long time ago.Įven after a motherboard replacement these computers got failing GPUs again.Sudden restarts because of kernel or GPU panic.Sudden restarts with a message: “Your computer restarted because of a problem”.A MacBook’s screen does not turn on and stays black.
The screen shows colored or grey vertical or horizontal lines.MacBook gets stuck or shows white screen on OS loading.These MacBook models (A1286 and a1297) 2011-2012 known to have an issue in the discrete GPU (Graphics Processing Unit) that sooner or later fails and the computer will have the following problems: Macbook Pro 2011-2012 GPU failing symptoms If you are reading this you are probably having an issue with your MacBook Pro 2011-2012 (15 inch or 17 inch) and the problem probably lays in the discrete graphics card.
