Keyboard not working after battery replacement

I bought new battery for my MacBook Pro 13" Retina Display Late 2013 and the replacement was nice and easy and i were very carefull so i did not break anything.

The new battery was working but now the keyboard is not working at all there is not even light in the caps lock button and yes i checked if the ribbon cable was loose but its just fine. The mousepad is working just fine aswell...

You would make my day if you could figure this out because i bought the battery because i start school tomorrow...

What should i try??

What do you mean loose but fine?


I had this problem with my 2015 macbook pro. I first tried disconnecting and attaching the keyboard cable a few times but that did not work in my case but after I disconnected and reattached the ribbon cable that goes over the middle of the battery and attaches near the edge of the case the keyboard started working again. I guess it wasnt fully seated .


I have this issue but with 13 inch model mid 2014. Other keyboard functions work but then don't such as QAZ and the erase button along with volume increase. Then later on the A functions but others don't. I suppose either the ribbon connects or does not. Surely cannot be the case that it partially functions.


so was the other battery dead orrr so what i would say is try putting the old battery back in and try charging it overnight

Solution retenue

See step #27 of this guide: Remplacement de la carte mère du MacBook Pro 13" Retina fin 2013

Use a piece of electrical tape and stick it on the cable. Unlock the tab then pull it into a fully seated position.

thank you!!! /20chars


I by accident pulled the tape above the middle (while changing the battery) which was the keyboard zif cable and lifted the little retaining tab. I didn't realize i had lifted the tab, so many of the keys weren't working. The option/command/fn keys. Lowering the retaining tab fixed the problem.


by accident because it's shown in the tutorial on how to change the battery but has nothing to do with changing the battery!!! i wonder how many people give themselves this headache bc of that... add me to the list : /


I wonder which would be the equivalent for MBP 13 Retina 2015. I experience this now post-battery change.
