Can I interchange logic boards between A1052 (1.33Ghz), A1085 (1.5), A1107 (1.67Ghz) and A1139 (hi-res version) - suspect possibly not with the latter. I have a 17" A1052 that freezes after a few seconds of operation and I get black messages that tell me to power down and restart, or tell me “System Failure”. Am I correct in suspecting the logic board - it was working flawlessly yesterday.
A1052 logic board part number 820-1524 dosnt seem to be suitable to others Try seaching google with part numbers if somethings shows up If the part number dosnt match i’d not try crossfixing like this. You might kill more parts even
