Unresponsive Keyboard and Trackpad problem FIXED/RESOLVED

slexus,

I've just called pbparts.com on your behalf, because they had provided me such a pleasant experience.

The cable you need for an a1229 is http://www.pbparts.com/shop.php//%5E9229018 - to make sure, before you order it, in very small print on your existing cable, the rep at pbparts told me you need to look for the following numbers:

821-0515 / 632-0528

There are also other numbers, if you visit the link above, in invisible print (for the search engines), if you "select all" on that page, they should be visible to you.

They have ONE in stock at the moment if you want it!

Good luck!

slexus,

Sorry - I've just had a look at the cable that I pulled out of my machine and in order to see the numbers, you have to be looking at the underside of the cable and yes, they're TINY...assuming it's the same for your a1229 then have a look at the image and you should know where to look.

Cheers!

thanks for the help. in the meanwhile i've received a spare part off ebay for $30ish incl worldwide shipping. there is no apparent wear spot in the bend like demonstrated in my photo a few messages back. installed it today, but there seems to be no apparent change in the broken behavior. i left the machine alone for a few hours, only for the internal input devices to be dead again when i came back. not a **** thing in dmesg again. looks like the only thing that can pick up this event is HardwareGrowler and i've now set it to use MailMe plugin for USB disconnections.

while i was working on setting that up off a fresh cold boot (warm reboot wouldn't wake up the built-in input devices), i saw a disconnect/connect cycle take place. when and on what conditions it can reconnect itself, i have no clue so far.

Spare part? As in, used, might not work, came out of another machine?

Or new, sealed, never used?

I've turned off notifications for this discussion...good luck! If it's not the ribbon cable, could be the rest of the top case assembly...not one person has shown me a permanent fix that was software or firmware related - I think you're going to be banging your head against this machine for a very long time if that's how you're approaching the problem

...again, good luck...

Worked like a charm!

Thanks!

One thing I noticed was I had removed the little square film tape thing from the that area, as well some some orange looking tape from the ribbons and forgot to put them back once I had swapped out the logic board (thanks NVIDIA!)

Now I have a macbook pro running like new! Thanks for the tip!

Cheers,

Natre 🙂

What type of tape did you use? I'm not great with technology so I'm not sure which tape is best to use. I'm eventually going to take it into the apple store to get it permentantly fix but I'm a full time student around finals week and can't part from my laptop for that long right now. I just need this as a quick fix for now.

I just used masking tape but Imust warn you its back to acting up again. I am gonna try and rig it up agai nwith some elctrical tape and clean off the tips of the wires connected to that little MINI board or whatever its called. It was working great for a few weeks but now as once again stopped responding 😢

I will let you know how I get one but I reccomend using electrical tape to "press" down on the ribbon cables as per the original discussion.

Hope it works for you!

Cheers,

Nathan

I had a similar issue on a Macbook Pro 13". I tapped the bottom of the Macbook firmly with a rubber mallet six or seven times and it worked like new. The trackpad became depressable again, my mouse stopped being "right click only", and the keyboard started working again.

Well, 3 years later this post has saved another one! My macbook pro's keyboard and mouse slowly started to quit... after a few reboots they stopped completely. So, I took it into the apple store to the genius', lol, and they told me that it needed a topcase for about 300 bucks ooooor I could buy a new one for 2500 bucks. That's a lot to spend on a 3 year old laptop and I'm not ready to drop the cash for a new one!! But with a little help from google, and some creative googling, I used the napkin trick and it works great again!

Thanks!

AND ... in 2012 ( 4 YEARS !!!!)

My MacBook Pro 17" has unresponsive Trackpad ...

THANK YOU --- SO VERY MUCH --- FOR YOUR "TIP" --- Steve Eugene is a "LifeSaver"

This should be filed under keywords: TRACKPAD TRACKPADS NOTWORKIING UNRESPONSIVE BADPAD

AND ...

Isn't it about time that Apple initiated a RECALL of these PowerBooks Laptops MacBooks --- and fixed them?

I have had this same problem and the one thing I discovered is the battery menu and the profile report show the battery needs to be replaced. I took the battery out and the trackpad and keyboard freezing has stopped. I think the problem is with having a bad battery in these models. On the old models it wouldn't matter but on the 2008 models it seems to matter most. I think the bad batteries heat up too much affecting the trackpad ribbon first and eventually other parts of the system. From everything I have read, no other remedy has worked indefinately... Not even rigging it with tape. In fact those that are rigging it with tape say the issue comes back even worse eventually. My advice is the moment you begin to discover these symtoms you should check the battery status and if it is bad, take it out immediately until you can replace it. If the new battery doesn't fix the problem then the problem is that apple has done another screw up with the battery and failed to do a recall again on them. Rigging your computer with paper or anything that could create static for that matter is the reason some of these people might be coming back with horror stories about how this solution worked for awhile until they lost their whole motherboard. Reason and logic tell me the answer is much more simpler than that. If the ribbon needed to be pushed down why would taking a bad battery out work? I think people are acting out in haste on this and I think the paper/tape remedy is absolutely absurd. I won't even try it! I know as a FACT the problem has much if not all to do with the battery. I just bought a referbished 2008 MBP to replace the last one I bought from the same company but the first one I got was stolen. The battery in that one was fine but, how could they overlook that this one was disfunctional? IT SAYS IT RIGHT THERE IN THE BATTERY STATUS!!! I don't think this is the case with all the batteries but, I do believe there are some batches that were manufactured with flaws. It is unfortunate that Apple has ignored this problem and nobody has stepped up to the plate to force them to see the issue. I am running Lion and I don't install junk on my computer. I happen to take very good care of my computers, always have. Apple is the one company out of all the others that avoids accountablility for expensive mistakes. They know this one is damaging computers to this day. They would have to replace tons of computers, batteries, etc. if they were forced to approach this. Instead they will perfect the new systems and sweep the rest of the dirt under the rug. I am a student right now and for 20 years I have used apple in both school and my graphics business. There was a time they were flawless... I always got my money's worth even when Gil was president. BUT THIS TRACKPAD/KEYBOARD ISSUE STARTED OFF THE SAME QUARTER OF THE YEAR THESE SYSTEMS CAME OUT AND APPLE CARED NOT TO FIND OUT WHY!!!!!!! They have always had a bad habit of assuming the customer is stupid when it comes to legitimate issues. Figures they would throw a new top case and keyboard in and send it back to the customer without researching the actual cause of this. Of those people, the problem has returned over time. You have read of all these people on this site and others who have used the "surpress the ribbon trick" but how many of them are returning 6 months later to tell you the longterm results? I've read a quarter of them longterm results and THEY ARE NOT GOOD. They all account the problem getting worse and some even lost the use of the hardware. Some say it is software because they don't have the problem with Windows on their macbook but some of those people came back and said eventually it DID start to present itself in Windows too. PERHAPS PEOPLE IT'S NOT THE RIBBON BUT THE FACT YOU TOOK THE BATTERY OUT FOR AWHILE????? CUMMON!!! LEAVE IT OUT AND REPLACE IT IF IT HASN'T ALREADY ESCALATED THE PROBLEM. It is OBVIOUS this problem DOES escalate over time. Apple is not going to back you up, so use common sense because it is the only thing we have left to count on. I use to tinker with corrupted system files all the time back in the 90's until I knew the older system software inside and out. I had to because Apple sure as **** wasn't going to tell me how to fix a flaw in their system software that incidently would cause ITSELF to corrupt. Again, they would just come out with the next version of software for a hundred bucks and sweep the old dirt before that under the rug. It's the name of the game! Sometimes you win, sometimes you lose. Technology is a real dog eat dog world and an expensive one to stay alive. I am hoping I took the battery out soon enough! I will know for sure when I get a undefective battery. I love this computer as the last one that was stolen. I worked hard and spent a lot of money to buy the **** thing twice in one year. I hope I am not going to turn out as a victim in this investment. I am tired of being the victim. Best of luck to all of you but you are on your own. Apple has clearly ignored this issue and I strongly down they are going to backtrack to previous years to give a **** about how they left a small percentage of customers flat broke with nothing to show for it. VERY VERY SAD INDEED!!!

Hello all,

I am hoping someone smart out there can help me - I've scoured all the forums and no one seems to have a problem quite like mine.

2.5 weeks ago, I had the cracked topcase replaced on my early 2008 macbook by a local dealer (this is a free repair done by apple on the defective old topcases, even if your computer is out of warranty). I was very happy with my shiny new-looking macbook until 2 days ago, when the keyboard and trackpad stopped working. When I phoned the company, they said it would cost $150 just to *look* at my computer, despite my mandate that I didn't have this issue until the topcase was replaced by their staff. They told me that it was "practically impossible" for the keyboard/trackpad issues to be a result of their work. However, after having tried just about everything I can find out there on the wide world of google, my mouse and keyboard still work only rarely and intermittantly - sometimes a reboot will resurrect them, but once they stop working nothing helps except potentially the reboot.

Specs:

Model Name: MacBook

Model Identifier: MacBook4,1

Processor Name: Intel Core 2 Duo

Processor Speed: 2.4 GHz

Number of Processors: 1

Total Number of Cores: 2

Here's what I've tried (to no avail):

- Reset PRAMS

- Reset SMC

- Took out battery & put a piece of "flller" paper in
- Removed Kextstats that weren't Apple
- Repaired disk permissions
- Re-indexed spotlight
- Disabled sleep

Here's the console readout:

Once this happens, keyboard/mouse lose functionality and also disappear from the USB device tree (would usually appear in the same USB Bus as the IR receiver.

Any help would be appreciated, either on how to solve this, OR if anyone else has run into this issue after having their topcase replaced, OR if topcase replacement was given as an option to them as a 'fix' for this issue. If I cannot fix this myself, I would ideally like the store to at least *look* at the macbook to ensure the damage wasn't done during the topcase replacement....but like I said, at this point they want me to shell out $150 just to look at it. I am hoping that if others have had the same problem I can at least convince them to look for me.

Thanks very much all for your help!

danisirek, it's very rare for a new top case to fail in this way. The most likely cause is the connector from the top case not properly inserted into the logic board socket, or dust in the connector that was never blown out. You would think the service provider would have spent 5 - 10 minutes removing the top case to check it out. They sound quite mercenary. Was there also cracking around the two raised ridges on the top of the display bezel? If so, that should have been changed too, as the replacement top case for your Macbook also shiped with a FOC bezel.

Hi techiesteve,

Thanks so much for your quick response. There was indeed also cracking around the display bezel, and they did replace that.

When I phoned them and mentioned that I thought it could be "just a connection issue", they told me that it was "practically impossible", as it takes "quite a bit of muscle" to get the connection in and out. Having never removed the topcase myself, I have taken their word on this....but it seems to me that whether it is difficult or not to remove, that it would be possible to have the connection not fully in.

However, that being the case, they argued that if it were an issue of connectivity, it would have appeared before 2 weeks had elapsed. Do you have any thoughts on this?

Many thanks.

As you likely do, it seems too much of a coincidence this should happen a few weeks after the top case was replaced. The connector has a small black thin plastic tab on it to pull it out of the socket on the logic board. It does snap into position, but it doesn't require 'muscle' to insert or remove. Although the top case cracking issue is covered by Apple for up to 5 years from dop, the part fitted also has Apple's standard 90 day warranty for any other issue. Unfortuneately, AASP's do have the right to charge if a problem isn't covered by Apple warranty. I replace a few top cases each week at work, and since the cracking issue materialised, have only seen a few DOA new parts, spongy trackpad clickers or completely dead, can count on one hand, quality is good. Yours isn't completely dead, as it still powers on. The one connector carries data from the trackpad, it's clicker, and the power switch. Only once did I replace a top case, test before screwing it down, and had a keyboard problem that was resolved by reseating the connector. The problem can only be caused by connector seating, the top case, or logic board. It's a shame you don't have an Apple Store nearby, I'm sure they would be more obliging than the people you used.
