Keyboard and trackpad stop responding briefly

I have a late 2012 (current generation) MacBook Air with all software up to date.
Every so often (sometimes multiple times per day, sometimes not at all) my keyboard and trackpad will stop responding to input for 1-10 seconds.
This has been happening since the computer was new.
Every time I go to the Console after I regain control I see the following:
[date] [time] Dock[processID]: no information back from LS about running process
There does not seem to be any prerequisite to that line, sometimes it's the only output written in the last 30 seconds.
Does anyone have any idea what's going on here?

If this were happening to me I would suspect a third party software conflict.

[SOLVED]MacBook Air (3,2) keyboard and trackpad stop responding int...

Hey guys, I've now got arch running on my air perfectly I think, except for a random loss of trackpad and keyboard input. It happens even with a usb keyboard. I'm not sure if the whole laptop is freezing or only the inputs stop functioning, I believe it is the latter because things that blink or move onscreen like the cursor keep blinking. It happens both in X and out. I have no idea where to start for diagnosing.
My current kernel line is this:
options "ro root=LABEL=arch arch noapic irqpoll acpi=force noefi"
I'm using nouveau but it also happens using fbdev. I can't get nvidia to work, it just blacks out the screen when starting X.
Any hints are welcome
EDIT: It just happened again, this time just after I clicked on a tab in firefox. I hit refresh, so the spinning circle came up on the tab, and the windows partially reloaded, then the mouse pointer stopped responding. The loading circle then stayed spinning indefinitely with the page failing to load any further.
Further information:
I removed noapic, irqpoll, arch (is that even a valid kernel option?) and noefi from the kernel line for this boot so that all that was left was acpi=force and it still booted happily. I'm not sure if I need any of those, I can't remember why I added them, probably to fix this keyboard issue. I'm booting through rEFInd so maybe I shouldn't have that noefi entry anyway.

Solved, I removed all boot options and I'm guessing one of them was causing it.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

Macbook air with 10.10.1 keyboard and touchpad stop responding after login screen

Keyboard and touchpad works only at login screen.
I have tried all the PRAM and SMC. reset stuff.
Safe mode, repair etc. Creating another account is not helped either.
I am also using 10.10.1 with macbook air.
I have also called the apple tech support and no results!
And this is obviously a software bug from so called robust yosemite!
Same here!
Macbook air built-in keyboard/trackpad only work at login screen

You may have to take the computer to the Apple store to have it checked out.

Dropped mid 2013 macbook air keyboard and trackpad not responding

My laptop slid off of my desk and onto the floor earlier this week. After checking to see if everything was okay- it was not!
My trackpad and keyboard are now unresponsive.
Macbook keeps searching for an external keyboard/ mouse.
Some reviews say to remove the back case of the laptop and make sure everything is plugged in. Other reviews say to reset SMC and NVRAM. I am currently backing everything up , but which route is best for a dropped laptop?
thanks in advance!

Take it to an Apple Store or Authorized Apple Service Center to see if it is salvageable. Sounds like it's very likely not salvageable.
Hopefully you have a good backup, created before this catastrophe.

Blackberry Curve 8520 keyboard and trackpad stopped working suddenly!

This morning when I was texting on my blackberry I noticed when I was pressing the s button it would press the a button as well. Now for some reason, the a button, which is also the lock button stopped working. I switched my phone off and took out the battery, switched it back on and now it won't light up unless I am pressing all the keys repetitively for about a minute or two. Sometimes when I do get it to light up, it won't let me select anything. Does anyone know how this can be fixed? Its definitely not water damaged and it's out of warranty (I just bought it a week ago from family believe it or not!) Thanks.

MacBook keyboard and trackpad not working

Hi,
I have had my MacBook for about a month and it has been great. However yeasterday the keyboard and trackpad stoped working. I have been abble to use it with a usb keyboard and mouse, but obviously this is not a permanent solution. There seems to be no connection between the computer and the mouse. The lights on caplock and numlock don't work and in System Preferences> Keyboard and Mouse there is no trackpad option. I assume an internal connection has come appart but I don't want to open it up as I am not perticularly experienced in these maters.
Any feedback would be apreciated

OK, I have had the same problem. I had a look on these forums, but the best thing to do is call Apple Support. They told me to do the following:
Unplug the mains adaptor
Remove battery
LEAVE the machine for like 50 seconds.
HOLD Power button for at least 5 seconds.
Install battery
Attach power adaptor
Before turning the machine back on, hold down: Option Key (Alt. with the switch symbol) Control (Apple symbol with square thingy) P and R.
While holding these press the power button, KEEP holding them, and the machine will restart again, chiming again, KEEP holding and the machine will restart a third time: on the THIRD restart and the THIRD chime, release the keys, and the login screen should come up, and machine should be OK.
This is what worked for me.
Incidentally, last night the machine stopped recognising the keyboard and trackpad, but responded with external devices, but this morning, it wouldn't even start. This solved both issues, it is so far working fine.

Keyboard and Trackpad freeze on 10.7.2 because of hidd process

Hi everyone,
I am running OS X 10.7.2 on a MacBook Pro 4,1 Penryn late 2008.
My keyboard and trackpad stop working randomly and it's been happening for the last few months. Nothing can be done but a restart of the computer.
I found out after doing some reasearch online that it is because of the "hidd" process. Now what I do as a workaround is I use my magic mouse to force quit the hidd process because it seems like bluetooth is not affected (thankfully). hidd restarts automatically and then everything works again.
However, it's getting worse and I'd like to find a permanent fix for this, as it now happens a few times a day. It is SO ANNOYING when I'm working on a design or something else important without having time to save...
I know there are similar subjects on the forum but none of them apply to my case directly. Is there anything I need to reinstall, or a preference file I need to delete to fix this?
I fixed the permissions with OnyX, clean caches and everything, nothing works so far.
Thanks in advance,
BS0D

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Boot in safe mode and log in to the account with the problem. First, disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable, and remove all aftermarket expansion cards. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including your login items.
Test. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

Keyboard and touchpad stop working

Hi everyone.
I've used my HP Mini 2140 Notebook PC for about two months. Two days ago, while I was working, the keyboard and touchpad stopped responding so I couldn't do anything. The computer kept "working" though. The computer won't go into sleep-mode when I try that; it just fades out the screen and hangs. Since then, this has started happening at total random.
I've tried this across two installations of Vista Home, and have uninstalled/reinstalled device drivers. I noticed that whenever this happens, the laptop's fan accellerates to what seems like full blast, and keeps going like that until I force the power off.
I've tried unplugging the AC adapter and battery, holding the power switch to drain power from circuits and booting up again, both with AC only and battery only. Neither of these things helped.
Wondering if anyone has seen or heard of a similar problem? Very frustrating.

Have EXACT same problem! Only my keyboard and touch pad freeze up after I have let computer run without touching it for several minutes!
Have no problem if I continually use keys or touch pad!
Have extended power saver times to over 5 hours with no help!

Stuck at login, Keyboard and Trackpad not working.

I don't know what happened, but this morning, all of a sudden my keyboard and Trackpad stopped working. I have recently upgraded to Lion and ever since had some minor issues here and there, but this is something really new. I suspect the last update did something, but I'm not sure. Thanks to my friend, he let me use his Mac to post this. I'm totally puzzled about what to do. The keyboard works just fine prior to OS X load, I can tell this because when I hold the Option key the boot manger window comes up, but both keyboard and Trackpad stop working during the login phase. I'm confident that this is a software issue, I just don't know how to fix it

I have found, when this problem exactly occurs. In order to reproduce this problem, click on Apple icon and then Restart, untick Reopen windows when logging back in. After system is restarted the keyboard and trackpad will not work, and the only way to solve this is to manually restart your Mac, by holding down the power button.

2012 13" MBP keyboard and trackpad inop after OS loads

I have a 2012 13" MBP (non retina) that had water spilled on the counter that pooled around it and some seeped into the bottom (don't ask how). I have taken it apart, cleaned it with alcohol, baked it to ensure it is dry and now almost everything works.
The odd thing is that the keyboard and trackpad will work during system boot to, say, reset PRAM or boot into safe mode or select any other combination; however, when the system boots into the OS (or recovery mode, etc) the keyboard and trackpad stop working all together. I can connect an external mouse and keyboard and it works fine...I installed a fresh HDD with a fresh copy of Yosemite and still have the same symptoms.
I doubt it's a hardware related issue since they both work on startup, but for the life of me I can't locate the issue that prevents them from working. I have turned off BT, reset PRAM and SMC, reset by holding power button in for a long time after shut down, all with the same results.
I also replaced the top case (new keyboard/trackpad) and have the same results....
What's interesting is if I keep pressing caps lock while the system is booting (press once per second) the keyboard and mouse will work after boot, but then stop after a minute...which is some progress I guess. I am going to try and reinstall the OS one more time and see if that makes a difference....I have reached the end of google and am out of ideas....anyone have any thoughts?

Update: I've justed attempted a boot from a Mavericks install USB stick. The trackpad and keyboard are still not recognised.
Unless I'm mistaken, I've either a very odd hardware fault, or something has got scrambled with non-volatile memory/firmware.

Built-in keyboard and trackpad not detected, what happened?

Hi there,
I was just using my mac book pro as I always do and suddenly both the built-in keyboard and trackpad stopped working.
I rebooted the mac book but then I received a message that neither a keyboard nor a trackpad were detected so the system started to look for bluetooth versions of them. I am only able to type this post using an old usb keyboard and mouse I found in my stuff.
Does anyone have the same problem?
I am using a Mac book pro 15 inches from 2011 with Mavericks 10.9.2
Best regards,
Cicero

I see that this was a problem many months ago, but I just had the same issue with my 2008 Macbook Pro and I want to post the solution for others who may search here for answers. My keyboard and trackpad stopped working soon after I downloaded Mavericks; but the OS was not the issue. The issue is apparently that the ribbon cable, in the battery compartment, connecting the keyboard and trackpad to their internal USB board needs pressure against it. I had recently (about a month and a half ago) replaced my battery with one from the Apple Store and, at the time, I noticed that it did not fit as snugly as the previous one. The solution I found (at least for older Macbook Pros) is on the following webpage:

Good luck!

Keyboard/Trackpad stop responding; OS still functional

Hi
I recently got a new retina Macbook pro 13" on Tuesday (arrived Thursday). Everything has been functional until late on Friday, where the keyboard and trackpad input stopped responding. The operating system in the background continue to work (I was watching a youtube video at the time which kept playing, and a file I was transferring via SFTP gave a notification when complete). While the system is in this unresponsive input state, plugging a usb mouse/keyboard does not work - they otherwise work fine. To resolve, I had to reboot the laptop through via the power button.
There is no messages in the console that suggests anything obvious in the Console, but maybe i'm just missing something.
Anyone else experienced this?
OS X 10.9, late 2013 rMBP 13".

Many people are experiening this problem rght now. It is not due to the new MacBook you bought but rather that the new operating system "Mavericks" has some glitches. They should be fixed soon so be looking for an update. Best of Luck!

My keyboard and trackpad occasionally do not respond for 1-2 minutes.

I bought my MBP new in July of this year and since I've had it the keyboard and trackpad have randomly stopped responding. It happened when I had lots of programs running at once and when I wasn't running anything. I took it to the Apple store and the genius said I needed to "ground" it by plugging the magsafe charger into the wall socket with the extension with the 3rd bottom prong. I've since done this and the keyboard and trackpad continue to freeze. I saw the update for this problem and it wouldn't let me download it because it said my computer didn't need it. I assume this is because my computer already has the update on it because it was made after the update came out? Has anyone else experienced this? Any solutions?

This isd a common problem for users who bought there Macbook Pro before March 2008. You should try installing the update again. If that does not work try to use an external mouse and keyboard to test if this is a logic board problem which could effect the USB ports causing them to not work either. If that's the case take the computer to apple and have the do a full diagnostic on it to save you anymore headache. You could in theory do the Apple hardware test yourself by taking you original Leopard install DVD and booting into the hardware test by holding D when you start up.

Keyboard and Trackpad just stopped working completely

Hi, I'm on a MBP 2.4 GHz running 10.4.11. Beginning yesterday my keyboard and mouse completely stopped working. This happened twice. The first time I got them working again with a hard shut down, the second time I got them working by closing the screen, putting the computer in standby. When I opened the thing back up, everythign was working.
Today, though, when the keyboard and trackpad quit, I've been unable to get them working again.
My problem is similar to the ones experienced here by MBP 2.4 and MB Air owners:
http://discussions.apple.com/thread.jspa?messageID=7194888
With the difference being that I'm on Tiger, not Leopard and I can't get the key or pad to respond at all. The solutions offered at that thread don't work for me.
I've plugged in an external keyboard and mouse and those work fine.
Any help you can offer is appreciated.

Related to the keyboard and mouse or trackpad not working, I've found of late that the whole lot freeze up and that wretched spinning timer takes over ad infinitum. Only way out is to hold pwr button the customary 6-8 seconds, then re-start with pwr/option.
Problem could be related to (Apple) upgrades as it's after a new one that this problem creeps in.
Makes me want to either revert to Factory settings or, Heaven forbid, give this MacBook Pro the float test and go back to Microsoft or even dig out the old steam typewriter.
The latter may be the best option - my life has definitely NOT improved since I invested in this heap of junk and the almost daily offerings of wonderful software by Apple are now set up for Spam, they're such a waste of time...
So, that's my Sunday moan.
If I leave this thing alone while I make a cup of tea I'll find it frozen again by the time I come back - any help on this from anyone??? (Steam being a bit pricey these days)
