Chosen Solution
I replaced a dead battery on my MacBook Pro and now the keyboard and trackpad aren’t working. The battery works fine, but the fans come on like gangbusters and won’t go off. I can use a remote keyboard and plug in mouse but the fans blow and blow. I did my best to reconnect the track board ribbon but clearly something is amiss. Help!
It sounds to me like something just isn’t connected properly. IIRC there’s a temp sensor integrated into the touchpad, and if it’s disconnected the fans will run full blast. I’d probably just re-do the repair and reseat each connector really carefully, making sure the ribbons are straight and fully inserted, and that they aren’t connected upside-down or damaged in any way. Let us know what you find. Good luck!
Have you tried reseting the PRAM/NVRAM or SMC?
I had the problem after replacing my battery that the touchpad would move the mouse pointer but it wouldn’t left or right click. I looked at the original battery pack and realized a thin metal covering that went over the touchpad was pulled off when i removed the battery. I pealed it off the original battery and put it back over the touchpad and reinstalled the new battery. It fixed the problem and everything is working well know.
This thread was a life saver. I had this exact same problem after changing out badly swollen battery on 2017 MBP. My trackpad and keyboard worked fine before battery change but stopped working after new battery installed and both fans going full speed non-stop. Did all the resets and recommendations but nothing worked. Took to two different “computer fix it” places who told me 2017 “tough to repair” (?) and that I “probably” needed a new logic board. I found this thread and ordered a new trackpad with ribbon on ebay. Just installed and it fixed everything. MBP back to normal. What a life saver.
Can you post the link to the trackpad and ribbon? (But only necessary if the MBP was an early 2015 retina model, or just like it.) Thanks!
I just replace the battery on a macbook pro 13" early 2015. I notice that the click on the mouse pad is gone, but the mouse and the keyboard is still in function. After I have been using the mac for couple days, then I notice that the keyboard and the mouse just falls out and I have to restart the mac to get the keyboard and mouse working again. Have someone in here had the same experience? could it be defect keyboard/mouse ribbon?. I have reset NVRAM and SMC, but still the same problem
