Mac Book Pro bought on the 14 Sept 2017 15" 2.8Ghz Quad Core 7th Generation Intel core i7 processor. Turbo boost up to 3.8Ghz 16 GB 2133 MHz LPDDR3 256 GB SSD Radeon Pro 555 2GB The screen flickers when ever booted (when ever open the lid to wake up). I took it to Genius Bar today. It needs Logic Board replacement and will order for the part and do the repacement. I am not sure if it is the same problem as that I encountered with my 2011 Mac Book pro and its discrete graphic card? Has Apple not resolved that type of problem in its latest Mac Book Pro products? I am very anxious if it is going to do the same as what happened to my Mac Book Pro 2011? Could any one tell me if there is a problem recognized with Mac Book Pro 2017 and its discrete Graphic card?
