Why did my internal keyboard and trackpad stop working?

If it still under warranty, take out AppleCare and extend your warranty for two years. I doubt the problem is going to go away on its own, Then take it back to Apple and get it fixed.

"If it is out of warranty, you may want to look at the connector where the cable coming from the trackpad and the keyboard connect to the main mother board.

I've seen a few with crud on the keyboard connector, and cleaning (once it also needed reflowing the connections) fixed it.

I may be wrong, but I think at the time we are writing this, Apple is facing an issue with these keyboard and trackpad failures, and requiring Apple service providers to run a diagnostic test on all laptops they receive (regardless of reason they came in for) while the laptop is connected to a server that feeds the info back to Apple. A program may be in the making."

"Most likely the trackpad cable. On the 2015 models, if the trackpad cable is not plugged into the logic board, the keyboard and trackpad will not work. I have come across a few where the keyboard and trackpad will intermittently not work, reboot usually temporarily fixes it, but in all cases the trackpad cable has been the issue. Sometimes the cable looks fine, sometimes it has slight liquid damage.

It is very easy to replace (remove bottom cover, disconnect battery, then disconnect the cable) and it is very cheap. Try this first, and it should sort out your problem."

"Hello, I just had the same issue this month. The keyboard and the trackpad both stopped working and the only was to fix it was to reboot. I also noticed in the log the message:

""Error: AppleHSSPIController::doSPITransfer NAK received from device"" followed every time by

""Error: AppleHSSPIController::doSPITransfer CRC from device was invalid: compu..."" and sometimes

""Error: AppleHSSPIController::InterruptOccurred Failed to transfer interrupt data with Err (0x00002eb)"".

My MBP Early 2015 was still under warranty and the support told me it was related to a connector between the trackpad and the keyboard formally called ""SVC,CABLE,IPD FLEX,HA COPPER,13"" MBP"" on the invoice. The Apple's Genius ran some diagnostic tests but he show me the results and everything was 100% fine, including the top case.

The repair costs 89€ in France (10€ for the cable itself, 79€ for the hardware fix). Hopefully the repair only takes up to 48 hours (or so they told me, it's been around 5 hours and I'm patiently waiting, I already brought my MBP for other issues and the repairs were fast)."

"Spilled coffee on my mac, brought my mac to the store and it came out fine. Used it for more than a year and out of nowhere trackpad and keyboard working intermittently.

Same issue and they only replaced IPD FLEX CABLE. Funny because Apple store in the Philippinrs said that they also have to change battery and topcase but when diagnosed here in China, they only said the IPD FLEX CABLE is the only thing they changed. They saved me money but not 100% sure if the problem pops up again. Still have to retrieve my MacBook pro 2015 retina, this week."

Hello, I have the same problem but even after I changed the trackpad cable after 2 months the trackpad and keyboard not worked again. Does anyone have any idea what causes the problem?
