Hey guys/girls. So to get the big picture I need to tell the whole story. So I got a late MBP 15' 2011. Since day one ive had issues with it, I got my logicboard changed twice and now looking for a third change. I paid for the first one because my MBP was out of warrenty fair enough. So I got it repaired and then three weeks later it had to be changed again and I did not have to pay because of the 90 days warrenty. So what happened this time was I was playing on my MPB and then all of the sudden the screen went sideways and i had lines on my screen. So I figured after doing research that it was my GFX card that went out, and it also got confirmed by two apple tech guys. Now while opening it up I had weird glue pieces on my logic board, several places and the lead genius could not give me a clear answer. so after debating with them trying to get them to tell me what the glue was they escortet me out of the apple store. Afterwards I called costumer relation and told them what happened and how rude they were in there. In my defense the only thing i kept saying was that the solution of paying $300 for another logic board repair was not going to work for me. I kept asking them what kind of repair they had to do in order for my computer to work and they said logic board, but because my previous repairs was unrelated. Now my question is have anyone ever seen glue like this on a logic board ( I will post pictures. ) If no or yes what is your thoughts on what it is ? thermal paste? I really hope you guys are whilling to answer my questions.
