took mine in after it wouldn't power up and after spending an hour of service time £83 those half baked charlies told me my logic board was dead and would work out better for me to buy a new macbook pro.
i took it back home and thought i'd give it a go nothing to lose and had it working within 5 minutes, called the shop up and they were like oh but oh but.
i said i swapped the ram which it said they had done in the report, i dont want to go on but they even lost a screw for the case.
