Unresponsive Keyboard and Trackpad problem FIXED/RESOLVED

I've been dealing with this issue since early December myself.
I purchased the MBP in November and had nearly a month with out any issues.

I spent nearly two hours on the phone with Apple Care via a specialist trying to diagnose the problem yesterday.
He did mention that they believe neither the 10.5.1 update or the MBP 1.1 update were to blame for occurrence of this issue. (I remain slightly skeptical)

Let me give you a short rundown of my problems and what I've done to help resolve the issue. Hopefully it'll help some of you.. or help me (with some of everyone else insight) if it happens again.

The symptoms:
keyboard and trackpad become unresponsive.
The problem is intermittent but often is completely unresponsive at start up.
USB mouse and keyboards have full functionality.

Kernel panics often occur as well. Usually this occurs just after the keyboard and track pad experience extreme intermittent "on and off" periods.
The only option is to do a hard-restart which my or may not resolve the unresponsiveness.

Things I've addressed in my particular case:

1. The battery recall issue - my battery (6N745288YFTA) is OK.
2. Resetting the PMU - no change.
3. Re-installing both the 10.5.1 and MBP 1.1 updates - no effect.
4. pressing the Function + S key at start up and running /sbin/fsck -fy The HD is said to be OK
5. I just finished an Archive and reinstall of Leopard = this seems to have fixed the issue for the moment. I have not run the Updater to bring the OS back to it's fully updated form yet.


The Archive and Re-install DID NOT WORK.
Even upon downloading and installing the 10.5.1 and 1.1 update, I'm still back at square one.

I've also been experiencing these phantom keystrokes to the eject key and backlight myself lately.

I've resolved to wait for the 10.5.2 official release to see of that helps... If not then I'll break down and send my machine in for service.

THE SOLUTION:

This is a HARDWARE problem!

After playing around with removing the battery and noticing that this often returned functionality to the keyboard I surmised that this had some sort of physical aspect.
Sure enough, there is a section of copper colored tape/wiring exposed in the batter slot that is slightly bowed where it's smallest.
When I depressed this with my finger tip on this portion to basically flatten it out flush against the housing; I found that all functionality was restored!

You can see the portion in the picture below.

I haven’t had any problems AT ALL since I took a piece of napkin and taped it down to sustain pressure on this portion of bowed tape/wiring.


I have yet to call AppleCare to see what they suggest I do.
I will post a reply here when I hear their suggestion.

Same problem here. It's a design issue. My keyboard and trackpad also stopped responding, couldn't get past login ... The problem is that Apple ran the trackpad cable over the top of the battery. And as Macbooks get thinner and thinner, component are snugger and snugger. So, when the battery heats up, and it will when watching YouTube videos or running video editing programs as many of us do, the trackpad cable gets unseated from the connected to the trackpad board. I have an Early 2015 Macbook Pro, and this problem surfaced just after the 1-year warranty period expired. If I turn my Macbook Pro over and firmly press in an up and down motion over the bottom case (under where the trackpad, trackpad cable and battery are all 3 aligned, then turn on my laptop, I once again have a working keyboard and trackpad and can login as normal. This is not what one would expect from such an expensive laptop. As these things get thinner and thinner ... problems will crop up more and more.


Apple Support will tell you to reset your NVRAM and SMC ... but that is the canned reply. Resetting those do fix other problems: keyboard backlights and other wonky issues ... but it will not reconnect an unseated trackpad ribbon. And if you are out of warranty ... just purchase a replacement ribbon on ebay and install it yourself. Taking it to an authorized Apple Repair Center will cost you an arm and a leg, especially outside of the USA where there's no price regulation.

The link above is only for the Early 2015 (March) MacBook Pro ... you will need to research your models ribbon for replacement.

What a difference a day makes. Last night I powered off and removed the battery. Turned it on and it was working OK, but then the trackpad and keyboard stopped working a few minutes later while I was using the computer. I put the battery back in and rebooted. Worked fine the rest of the evening and then for the first time in a while it woke up just fine after about 4 hours of sleep with the lid closed.


However... I closed the lid and packed it up to bring to work. After running some errands, when I got to work and plugged it in - no dice (see console log below). Then, after rebooting (twice), trackpad/keyboard were still not working. I opened the battery case and pushed around on the cable some more (nothing, as expected), but after replacing the battery again and rebooting again it's working OK.


Here is the slightly redacted console log after reopening the lid:

When it still wasn't working after reboot, I saw these two similar messages:

8/2/12 11:17:36 AMkernelUSBF: 4.468 [0x8605100] The IOUSBFamily was not able to enumerate a device.



It definitely seems to point to a hardware issue with the ribbon cable at this point, but it seems that unlike others, mine will not start working again after the ribbon cable has been jostled - until the machine is rebooted.

@jj: At this point you could do a replacement for the flex cable and see if that helps. The cable is not expensive (around $25) and is not a difficult task to change. But in my case the problem returned after several months. I suppose replacing the cable every 6 months or so is no big deal but it's just as easy for me to use it as a desktop most of the time.


There could be more to your situation but start with the cheaper "fix".


BTW, did you ever try an external keyboard and mouse to confirm that they will work while experiencing the frozen trackpad/keyboard? That's an alternative way to get around the problem but surely not a convenient one.

Aug 4, 2012 6:45 AM in response to krissel

Well, it's been nearly a day now and even after many reboots and poking at the cable, I still cannot get the keyboard/trackpad to return. Luckily the external mouse and keyboard work fine or I'd have a brick. I'll order the replacement cable and see if it resolves the problem. I always use an external mouse at work anyway, but at home, I prefer to work not at a desk, so this will be a pain if I cannot resolve the issue. Also, even though I prefer a mouse, I still use the trackpad for some purposes (no pinching and stretching with a mouse).

I appear to have the same issue again. Faulty trackpad and keyboard. New part warranty ran out last month.


Another flex cable ordered. Going to complain to Apple if new flex solves problem. This must be a design fault.


One slight difference, I can only get the trackpad to work now and again, keyboard gone. The grey wire connection to the trackpad seems flimsy and I cannot get it to click into place. What is this wire? Wondering if I need to order another part.

Thanks Steve,

I took my 2007 macbook pro to the "genius" bar, and they stared at me like I was from another planet when I explained the very sme problem to them. They also told me I should "Just buy a new computer".

So much for geniuses...

Your solution works perfectly. It seems this is not uncommon.

Even though I totally prefer a mac over a PC, the lack of quality in construction (ie. wear and tear ability) sometimes really ****** me off.... especially for the price.

Hi everybody

Once, about 6-7 months ago I had the same problem, my trackpad and keyboard together freeze sometimes intermittently

Then I solved alone, putting a little thickness between battery and golden cable

http://i49.tinypic.com/16m8w3t.jpg

This method worked great until a couple of weeks ago, when keyboard and trackpad together stop to work definitively

Now I had to repair it, but I don't know if is enough to change the golden cable or I had to change the keyboard or if are unnecessary both solution because is the black connector in the logic board to be out of order

Someone could help me, someone solve this second step of our problem??

Thank you everybody

I have this similar problem about 4 months back on my macbook pro that was purchased in November 2011. Was quite disappointed with the quality that I kept it until this week when I decided to tkae it to the local Apple service centre for repair. They qioted me RM 2,435.00 ( about USD 760.00) to fix the problem by exchanging the logic board. Well one of the USB and the blue tooth were not working as well. should I do it ?

The trackpad on my MacBook Air stopped recognizing clicks. The curser position could be changed but nothing I was trying was working to get the clicker to work... SMC Reset, Zap PRAM, Disk Utility, Permissions... etc.


Turns out that the wireless mouse I had paired to the MBA and tossed into my brief case was being pressed by other items in the briefcase! Turned it off. Problem solved.

I have a 2011 MacBook Air 13´ with the same problem. After suffering the lack of reliability of the computer which means switching it on and not knowing if the keyboard and trackpad are going to work or not, I took the computer to the Genius (Apple Service). They thought that it was a trackpad failure or a keyboard failure or both. So they changed the keyboard. I was going to pay for it because the warranty expired. When I go to collect the computer I test it for a few seconds and the problem continued.


I spoke wth the technician and after some tests he told me that I had very bad luck. My only choice is to replace the base plate which costs more than 400 Euros. Much more expensive than changing keyboard and trackpad.


I have been several months with this problem, and has affected professionaly to my activities with the computer.


In the last five years I have been a great Apple fan, we have at home several Mac computers, Ipad, Iphone, Appel TV, Time machine, etc. Apple is more expensive than other computers but it was worth it. But when I pay more than the average I expect, as a customer, a good reliability.


And this has not been the case with the problem. I have a great dissapointment with Apple and I doubt that I will buy another apple product again. I shall move to Samsung and other companies but never Apple.


From seeing this community I can see that Apple has manufactured a product with a serious defect and I would expect a solution. This is what I would expect and thousands of unhappy customers that have read and written in this community. This is totally unacceptable. Someone from Apple should come up and give an explanation for such a defective product.


I have been seduced by Apple for a few years, but not anymore... since I have paid for a useless computer.


Bye, bye Apple.

I last commented in this thread about a year ago. I was using the MBP without the battery (on AC) as my way of avoiding the problem. But about 6 months ago I stopped taking the battery out. I usually have the AC plugged in anyway since this model doesn't have a great battery life (early 2008, 15" 2.5 GHz, 4GB Ram 10.6.8).


Here's the odd thing. I have only had the freeze up or the multiple lettering maybe two or three times since then even though the battery is in the unit. What I do get on occasion is the trackpad not really recognizing my fingers. Sometimes I have to wet them or rub them, wait a few seconds, then try again and the cursor will respond.


I wish I could tell you all why it seems to be better now, but I can't. Not complaining, mind you. :-)
