I see someone else had this problem back in 2019 and it was suggested the trackpad needed replacement. What would cause this with just a battery change? Is there anything else that would cause this to happen? How can I definitely be sure it’s the trackpad and not something else? Is there a troubleshooting procedure or is it a matter of changing it and hoping for the best? follow up question re: this posting. are the keyboard and track pad somehow connected together so that a damaged trackpad will cause the keyboard to stop functioning also? found a damaged cable on trackpad( got a bit too aggressive removing the battery) that explains the trackpad being inoperative but not sure how or if that is the whole problem. any suggestions?
Inspect the keyboard cable and the trackpad cable for damage. It’s possible these were scraped during the removal of the embedded battery. If you see any damage here this is most likely the cause of your issue. If just the trackpad cable is damaged and the keyboard is still non functional there might be an additional issue. If the keyboard cable is damaged you will most likely need to replace the top case which can be a pain. Alternatively you can disconnect the internal keyboard and use a wired external or Bluetooth keyboard instead. In the attached photos the red circle shows the location of the trackpad cable and the yellow circle shows the location of the keyboard cable. Hope this is helpful!
