Apple has finally rolled out a large-scale repair program to fix longstanding issues with MacBook Pro and Retina MacBook Pro laptops shipped between February 2011 and December 2013. The issue seems to be related to the soldering process of the GPUs, it affects laptops with AMD and NVIDIA GPUs so its not vendor specific. Apple doesn't provide specifics but it's rumored that the problems arose because the lead-free solder that's used to connect the GPU to the motherboard cracks through repeated thermal cycling.
As a result of the defect, affected laptops may exhibit distorted video, no video, or unexpected restarts. Full details of the repair program can be found at Apple. Customers can bring affected laptops to an Apple Store or service provider or send it in via mail for repair. Additionally, Apple also promises to reimburse clients who have paid for a repair either though Apple or an Apple Authorized Service Provider.
