Got this very dirty machine that gives no POST and off corse remain in black screen, I cleaned it up also with IPA can't see any corrosion or damaged components but still run only in SMC mode then I'm guessing its is an issue with the SMC but how do you troubleshoot SMC issues?
I got this machine after it was at another workshop, they removed the EFI U6100 and the U5870, I replaced them from a dead board but now i got fan spinning and stuck in the middle of boot line, I understand from someone that the EFI need to be reprogrammed can anyone guide me to it? Louis I know...
