Resoldering the U8900-chip on the non retina MBP mid-2012?
Hey people, i have a Macbook Pro 15 mid-2012 (A1286), so non retina here. It has a black screen, external video works though, sometimes i even get video on the internal screen when i disable the 650M by software-mod but it's very inconsistent. For the retina-model there was a common problem that the U8900 chip needed resoldering. But i couldn't find much on the web for the A1286 model: Where is the U8900 on that board? Is it the same procedure as for the retina models?
