I’m not sure where to begin looking for the problem. Can someone point me in the right direction? I have no Wi-Fi or Bluetooth after replacing the battery and speakers on my MacBook Pro 13 inch retina late 2012 laptop. I followed the tutorial exactly and did not seem to have any problems during the repair.

I’m an amateur here so I really appreciate your time. I made sure all cables were reconnected properly. In your opinion should I proceed with replacement of the recommended items? I was extremely careful when I replaced the battery so I don’t think I damaged anything. Are there any other things I should check first? The only other ‘symptom’ before I replaced the battery was occasional difficulty getting the laptop to connect to a Bluetooth speaker. It would sometimes take multiple attempts to connect with no apparent cause. Thanks again.
Try reseating the I/O cable, if that fails replace it and test again.
Will do thanks!
I’m having this same issue. Did you solve it in the end?

@henrychugh26 - Did you try resetting the cable and if that didn’t help replace the cable. 40% of the time reseating fixes it and the other 40% replacing is needed. And lastly 20% the board is corroded up.
