Replaced CPU , Mac seems dead. LED 1 ON, LED 2 goes on - off - on
Hi all.
Wanted to replace my i5 3,1 GHz with a I7 3,4 GHz ( a 2600 model) , replaced the logic board, but mac doesn’t turn on.
Replaced the known good i5 3,1 GHz, but same problem.
LED 1 is ON, LED 2 goes on and off (cycling) w/ short fanspin.
Anyway I can measure the PSU for defects?
Any other steps / defects I should check?
Is dit een goede vraag?

Hello! I have the same problem. In your second step I am in doubt if you returned the “known good” logic board or if you seated a known good processor in the new logic board. Can you please tell us?
