I've changed my battery after this question: Does battery condition have anything to do with macbook pro performance?

The performance has significantly increased, however I have a new problem.

My Macbook's Keyboard and Trackpad are not working.

At all. Only the power button works. I've connected an external mouse and Apple keyboard via USB slots. They work just fine, the problem is it's not a laptop anymore.

This happened after I changed the battery and replaced it with an iFixIt battery while going over their tutorial. I did use Listerine instead of adhesive removal, because apparently shipping them is illegal in my country.. Some comments said that's a good alternative, I'm not sure if this caused the issue or not.

After the keyboard and trackpad became unresponsive, I've read that the Touchpad Trackpad Ribbon Flex Cable is very sensitive and it easily gets damaged. I've ordered a new one and installed it, didn't help.

Right now I'm looking for more solutions on how to fix my device.

  • Did you remove everything like in the guide or leave in the logic board? Either way you could try disconnecting and reconnecting the keyboard ribbon (at the front by the battery (see step 33 on this 15" guide) as it is quite hard to push back into the slot. Perhaps it got dislodged when removing the battery. I used dental floss and alcohol to remove my battery and doubt Listerine would cause an issue if you didn't spill it everywhere (although I doubt it dissolved the glue much). – lx07 Nov 14 '19 at 22:02
  • No I didn't remove everything I skipped most of the steps like the comments suggested. While messing around trying to fix it I did try that. – Esqarrouth Nov 15 '19 at 1:31
  • I tried disconnecting and reconnecting that part again. Didn't help. – Esqarrouth Nov 23 '19 at 15:07
  • apple.stackexchange.com/a/246403/108839 I looked at the settings like this post suggests, and Apple Internal Keyboard & Trackpad seems connected – Esqarrouth Nov 23 '19 at 15:08
