1 Are logic boards interchangeable between the models?
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.
