I have replaced my A1425’s retina screen assembly and, after reconnecting the battery (everything’s in place, no issues with interposer) it’s not being recognised. I cannot start the mac without AC power and the battery menu calls for replacement. I suspect the battery is misconnected or the cables damaged. How would you troubleshoot this?
Hi! Did you solve the issue? If not, did you try resetting the SMC? Hope that helps!
