Keyboard and trackpad are unreponsive?

"Replace the trackpad cable. This commonly goes bad on 2015 13"" models, and causes intermittent problems with both the keyboard and trackpad (trackpad needs to be recognised in order for the keyboard to work on this model).

Part is £10 and takes 5 minutes to replace"

"I have the problem with Trackpad and Keyboard not working on a customer's a1502.. Before I go replacing any ribbon cable(s) for a Trackpad or otherwise, can ANYONE answer this..?

Why do both Keyboard and Trackpad work flawlessly outside of Sierra.? Pick ANY Linux distribution - I have 5-7 variants - and boot up to find KB and Trackpad ALWAYS working, ALL the time, without stopping or failing to work.. Thx"

"I had the same problem. It started when I forgot my charger at home and borrowed a MacBook Air charger. A day later the keyboard and trackpad had stopped working. I used an external keyboard and mouse until I have drained the battery. I opened the computer and tried clicking the trackpad cable in place. A day later I got back my charger and the the keyboard and trackpad worked like a charm again.

So I do not know it the problem was me charging the computer with the wrong cable or if the cable had been misplaced or a combination of the both.

EDIT: Since I wrote this post the keyboard and trackpad have stopped working a few more times. But now I have found the solution to my problem. I am pretty sure it is the trackpad connector that there is something wrong with. Disconnecting and reconnection the connector (see step 17 in this guide: MacBook Pro 13"" Retina Display Early 2015 Trackpad Replacement) have fixed the problem. I have also bought a new cable and will install that in my computer when it arrives."

I had a similar problem and was trying to hard SMC reset by opening the Macbook pro and unplugging the battery. This did not help, but after trying this I unplugged the trackpad cable and keyboard cables then plugged them back and it worked! I suspect a loose connection with one of them.

"Hi all,

a quick question to everybody who have replaced the flex cable and had normal functionality afterwards.

I would like to know if the trackpad still had its click response (force touch or whatever you call it) even though it didn't work?

I ordered a replacement flex cable off of Amazon and after installing it my keyboard and trackpad are still unresponsive. BUT when I click the trackpad, I don't even get a vibrating response telling me it registered my click. When I put the old cable in though, the trackpad and keyboard don't recognise any movement, but the trackpad recognise my clicks and gives a response by vibrating.

Now I'm not sure if the replacement cable is broken or if my issue lies somewhere else.

Greatly appreciate any response!"

Hey I am having a similar issue. My keyboard stopped working but my trackpad is still working fine. I took it to a repair place and they said that putting in a new keyboard did not fix the issue. They now want to replace the logic part on the mother board and reprogram it. I told them that it could be the cable for the track pad and they said that when they swapped the mother board the keyboard worked fine so it has to be the mother board. When i plugged in an external keyboard, it also didn't work. Not sure what to do. Should I still try to replace the trackpad cable?
