Internal keyboard and trackpad not working

I am currently using a Macbook Pro 13”retina 2015.

So i usually use my mac in bootcamp for work purposes. I connect my macbook to an external HDMI monitor and a USB mouse and keyboard. It worked fine, until after awhile, i turned on my mac and the built-in keyboard and trackpad were not working. The only key working was the power key. I could not enter recovery mode or used any start up command keys since the keyboard was unresponsive. It only worked with my USB( logitech) external keyboard and mouse.

No trackpad was detected in system preferences. The weird thing is it still force shutdown when i enter combination: shift+control+option+power button (so the keyboard is kinda working). In some cases, when trying to log on, a bluetooth device search tab appears.

I went to the apple store to get it serviced. The technician reinstalled my OS and formatted Mac. the inbuilt keyboard and mouse worked. and after using my external keyboard and mouse, everything stopped working again. He did not really know the cause of this problem.

I'm pretty sure this isn't a hardware issue as stated above, the shift+control+option+power button still works. I think there may be some error or setting problems.

Note: i have never dropped fluid onto my laptop or dropped it

Would really appreciate any help to resolve this issue. Thanks

Answer this question I have this problem too

Is this a good question?

I know this is an old thread, but the above answer is incomplete. For posterity's sake:

The symptoms OP described are consistent with a faulty trackpad or trackpad cable. The 2015 model is engineered differently than previous ones. The trackpad is now a necessary part of the chain for the system to interpret keyboard input. Thus this model has an issue with the trackpad and keyboard going out together - unlike in the past where a failing trackpad or TP cable would affect the trackpad only.

I work in an Apple repair shop and for some reason have been seeing this issue a lot lately. As in the OP's case, I've seen that power button still works, and the SMC can still be reset while the machine is off. Possibly because the system is ignoring localization / character mapping information now stored in the trackpad, unlike when the machine is on.

I do think you are on the right track here Colin. I will tell you this though, I have a machine in my shop experiencing all the same problems and I was able to get one other command to function, Single-User mode. Once in that mode I was able to do two things:

1. Verify that the keyboard itself was fully functional and all keys were typing.

2. Run /sbin/fsck -fy, which did resolve all the issues afterwards. Currently I have not figured out why but I suspect the answer lies somewhere in that communication you are discussing.

Note that the issue OP described is specific to the 2015 MBP, so resolutions from older threads likely won't work.

They changed two things in the 2015 model over previous years -

1. New trackpad - Force Touch model. As I said above, it appears to be a necessary part of the keyboard input chain now.

2. Trackpad cable ran along the top of the battery, rather than below it as in previous years, exposing it to any debris, crumbs etc that might be inside the machine. This is a complete guess, but as I posted below, my mom's 2015 MBP had this issue, and I did notice a decent size "ding" in her trackpad cable when replacing it.

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..

Fresh reload of Sierra, same thing. A couple of software updates and they worked, but stopped working again.. Boot to Linux, zero problems... Thx

Well this adds an interesting element to the mix. What did you end up doing?

I wish one of our veterans like @danj or @mayer would share their perspective on this one!

For what it's worth, my mom had this exact issue on her 2015 13" MBP a couple months back when I was visiting. Of course, resetting the PRAM brought back functionality, and it continued working fine while I was there. To be safe we replaced her trackpad cable ($60 off PowerBookMedic). 2 months later, the issue hasn't shown up again. I'll post an update here if that changes. While I was replacing it, I noticed some crumbs had gotten inside, and there was a crumb sized dent in her old trackpad cable.

@wisebeardy - Colin, this issue is tricky as there are many causes! Just like someone complaining about their foot hurting the cause could be someone dropped a brick on it, they kicked something hard, renched the foot running or have gout! Which ‘IS’ the right answer they all are!

Same issue here... a swollen battery, a worn cable, something spilled into the trackpad (spray cleaner) or keyboard being the physical things. The keyboard driver is out of date (failed to update in OS update) or in Ruben’s case Linux or MS Windows messes up the driver within BootCamp (or if running natively directly corrrupts it) In some cases a Trojan has tried to infiltrate the system!

Sadly, i’ve seen a few of these my self and we’ve helped a few people here with this maddening issue here: Why did my internal keyboard and mouse suddenly stopped working?

Hi, I'm not entirely sure if this will work but please give it a go because I'm posting this right after I managed to find the fix (hopefully a permanent one):

1. Shut down your MBP

2. Connect an external keyboard to your MBP

3. Reboot your MBP while holding the Shift key to go into Safe Boot

4. For me, my trackpad and keyboard instantly revived, and I just shut the MBP down and switched it on normally.

It took me ages to try this because all I could find were suggestions to reset SMC and PRAM. I even did a clean wipe of my MBP, nothing worked. I'm just posting this in hopes that it helps, but I'm praying hard that this is a permanent fix for me as well.

Hi! I have exactly the same issue.

Sometimes it works, a lot of times not, it seems as it is getting worse.

@wisebeardy, is it a problem with cables/connectors or something else?

Thanks,

Gregor

Yes - so far, replacing the trackpad cable and/or trackpad itself addresses the issue.

by

This is also one of the first things I try depending on what I'm told happened.

A common cause on the trackpad is spray cleaners! It seeps into the innner layers or drips onto the logic board underneath making a mess! People spray the surface Vs the cloth to then wipe the surface. This makes the difference of not killing the trackpad. The keyboard can also encounter spray cleaner abuse, luckily it recovers!

I am currently battling this problem. On four occasions I have fixed it only for it it occur a short while later. My problem seems to be associated with the ribbon clamp at the front end of the trackpad cable (under the front edge of the MB. When I re-seat it I get full functionality back (on one occasion only the keyboard came back however). The problem first occurred after carrying the MB in a bag against my back on a brisk walk, so it got a bit of a shake and some bending load. Since then it has become more and more fragile - I daren't move it now! The ribbon has a couple of stress relieving kinks in it next to this end which would normally reduce a pull on the connector if the battery where to move (or swell), but these create the unfortunate consequence that if pressed by the cover if it is slightly dented, by my back for example, will produce quite a large force to dislocate the ribbon end. I have inserted a little pad under the ribbon end this time to try to maintain some upward pressure on it to resist better any more compressions. Will it work for long? Lets see.. (I would add that there is no difference in appearance between a working clamped ribbon and a non working one, it is something very subtle and sensitive that is going wrong here)

I would recommend you replace the cable. You may also want to run CoconutBattery to make sure you battery is in good shape. I often see swelled batteries are pressing the cable against the bottom cover.

I also place to the sides (making a bit of a channel) where the cable runs some dense foam tape to help protect the cable.

Here's the part you'll need: MacBook Pro 13" Retina Trackpad Flex Cable, Early 2015 - Apple P/N 923-00518

Many thanks for the advice Dan, I see what you are thinking. My battery looked fine however, but I will try coconut. Replacing the cable could also improve the retention of the connector strip under the clamp, with a nice fresh surface for this to grip to.

by

Battery came up good on Coconut battery.

I reset the shape of the folds/kinks in the ribbon to ensure they would not touch the bottom case and had two days of reliable use, including carrying the MB about, then after overnight recharging (gets quite warm) the ribbon disconnected itself, without any external influence, just sitting there on the side board. Couldn't get it to work after that, at all.

Now I have a replacement ribbon in, as suggested by Dan, and it's working again. don't know if it will survive a recharge yet.

Fitting the ribbon is tricky, it does not come with the little sticky pads at the clamp end that aid the retention, I am re-using the old ones. Putting the kinks into the ribbon is also very difficult and, I suspect, critical.

by

I also employed the "channel" suggestion, from Dan, seems like a worthwhile experiment

All good, still... :-)

After all type of tests at the apple repair shop, days and days without my computer, all types of diagnostics, including blaming me for what I have active at login, they finally accept to change the trackpad cable. It has been a week, and it is working fine.

Trouble is that it appears to be fine, no apparent damage, fitted properly, but somehow there is still a problem that the new cable fixes.

It is a software issue. You can fix it by cleaning your desktop f any files, because some how, there are files that can corrupt the start up process, thats why you have to start it up over and over again until the trackpad is recognized again. Or, you can upgrade to High Sierra ant the upgrade will solve the issue.

No, it doesn't work like that. I have High Sierra with the same problem.

by

Yeah, this is not true.

by

Agreed! Wishful thinking cleaning the desktop of the files it has on it. The upgrading the OS might have merit if the driver was corrupted or out of date.
