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.

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 ?

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. :-)

just bought a new macbook pro retina 15, late 2013. had a mid-2010 macbook pro (not retina). on the 2010, my bluetooth keyboard, mouse, and track pad had co-existed peacefuly and simultaneously for a very long time. now, the new MBPR will only recognize the mouse. can't see the keyboard or trackpad. i could live without the trackpad, but the keyboard not so much. any thoughts on how to get it to recognize the bluetooth keyboard? thanks for any help you can give.

Wow, LB, are you really telling me you have a brand new MBP not responding to its internal KYBD or trackpad?

And cannot pair with your BT KYBD either? Yikes, you've still got plenty of warranty; back to the shop with it like lightning!

For the moment, try to pair your BT KYBD again. Put new batteries in it if need be. And the best of luck to you!

Jan 22, 2014 8:06 AM in response to hexdiy

hi hexdiy,


thank you for the kind words. thankfully, internal kybd and trackpad work. Keyboard and mouse batteries are 100%


after double checking for any external noise, many reboots, and patiently clicking back and forth in bluetooth-search setup windows for each external (keyboard and mouse). magic mouse was finally recognized for an instant ... saw it then lost it. once it finally showed up long enough to click 'continue,' the mouse ultimately paired ... this also took a few tries. had to reboot and repeat bluetooth-device-search process multiple times before it finally found the external keyboard. still can't pair the trackpad.


i honestly can't say anything positive about the macbook pro retina 15" late 2013 with mavericks ... i've had at least 10 macs. overall (not just bluetooth), this is worst Apple experience ever ... easily.

Just want to add a few thoughts to this ongoing problem which first befell me a couple years ago. (BTW, I have a 17" MBP and a new Air but I still go back to this MBP for many projects since I really like the concave keys much better than the chicklet style.)


Anyway, I have had this problem return very sporadically over the past year but nothing like it was previously, as I've commented earlier. I've found a few things that can give me back the trackpad and keyboard without restarting.


First, if I find the trackpad not responding, I either rub my fingers, warm them or wipe them with a damp cloth. Sometimes it seems as though the pad loses its ability to sense the finger. Most of the time I get the cursor to move again. I also take my finger and give it a push/swipe/flicking movement upward and sometimes this reactivates the cursor.


If those don't work, I've found that using the arrow keys can sometimes bring back the cursor and the rest of the keyboard as well.


Failing all of these attemps, I cast a spell over the Mac and swear a blue streak. Of course that doesn't give me back my cursor or keyboard but it makes me feel better. :-)

One more thing ...


Re: the original wireless-accessory-response problem


For magic mouse and late-2013 MBPR 15", I want to shut off "Scroll direction: natural - Content tracks finger movement" Deselecting the box in Mouse settings has no effect whatsoever. Every time I grab the mouse, the page/spreadsheet/graphic scrolls. And, I can't turn that 'feature' off. Urg. Does anyone know how to make this stop? I appreciate any help you can give. Annoyed and nauseous ...
