Keyboard and trackpad freeze and randomly become unresponsive

I've got a MacBook Pro (15-inch Early 2011) running Mac OS X 10.8.2.
Since a few weeks ago at random intervals my keyboard and trackpad become permanently unresponsive. I don't recall any particular cause or change that would have caused this to start happening.
What happens is that the trackpad and keyboard will stop functioning completely. The computer, display etc. would continue to function properly:
The clock keeps ticking.
If music were playing it would continue etc.
Internet connectivity (via an ethernet cable or WiFi) continues to work as well (a download will continue, and even resume if I disconnect and reconnect the ethernet cable).
Presssing the power button will bring up the shutdown dialog as usual (but I can't use it, obviously, so a forced shutdown needs to be performed instead by holding down the power button longer).
.. but the keyboard and trackpad are rendered inoperable, as if they were no longer connected.
I've made no progress in finding out what could possibly be the cause of this. A few observations:
It has never happened while not using the keyboard (e.g. watch a DVD with TV series for a few hours, and afterwards the keyboard would always be fine).
It always happens while actively typing (e.g. while in the middle of replying to an e-mail).
It is not a temporary problem, the keyboard and trackpad will not become responsive again after some time (the computer isn't particulary occupied with calculating something big, no beachball and no busy mechanical noises).
It does not happen progessively. It works fine and snappy one second, and I'm touching a dead keyboard a split second later.
I tried connecting a USB keyboard but that doesn't seem to work either (I'm mentioning this since some of the linked threads below close with that as a solution).
Possibly related (although I haven't found anything in these threads):
Keyboard causes trackpad to not function properly
Keyboard and trackpack freeze
Keyboard and Trackpad Unresponsive
MacBook Pro Keyboard & TrackPad freeze! Totally Unresponsive!
MacBook Pro inbuilt Keyboard and Trackpad freeze when not connected to bluetooth devices?
I've crawled through some log files in /var/log (via the shell and through Console.app) and found a couple things that may be relevant, although they seem unrelated. Etiher way, I was surprised by what I found. All sorts of errors with regards to Bluetooth and USB stuff. I'm not aware of using either. I haven't used bluetooth in years and though I sometimes charge an iPod by USB, I haven't had any problems with that, and this keyboard/trackpad freeze has also happened on sessions where I started the laptop and never even touch the USB ports in the time leading up to the freeze.
Sample log from when it happened. It last happened at 21:04:xx:

  • Keyboard and trackpad freeze and unresponsive

    keyboard and trackpad freeze and unresponsive happen occasionally.
    This is not a rare case. Please do not want to circumvent nor dodge the problem and issue. Don't pretend that this prolem is minor and not important.
    When there is something wrong, please admit that there is something wrong and appologize!!
    Be responsible for those people who pay $1,800 dollars, which they earn for working day and night and till late night everyday!!

    This Apple article may help you with this issue.
    Other users have reported that leaving any USB device connected to the MacBook Pro prevents the issue from occurring. A workaround for the moment, but not too onerous.
    Best of luck.

  • Why does my Macbook pro keyboard and trackpad randomly become unresponsive forcing restart in OSX Mavericks?

    Randomly when using OSX Mavericks, since installing yesterday, my mid-2012 Macbook Pro keyboard and trackpad freeze and become unresponsive.
    The computer is still running whatever I was doing, the computer does not crash, i just cannot control it and the only way I have found as a fix is to restart.
    This never happened in Mountain Lion.
    Can anyone help?

    Very similarly.
    Mac Mini late 2012. i7 CPU, 16GB ram. 12GB unused.
    After installing Mavericks, it seems to grind my system to a halt. It is still running (I can move the cursor and activity monitor updates processes) but every application I try to launch results in a colorful waiting sign. It even can take a minute or more before an application shows "any" sign of starting.
    I tried to open a terminal session (so I could manually kill a process) but the terminal session did not even process. It timed out after 5 minutes.
    Acitivity monitor shows 90-95% idle and I have no idea what's causing it.
    I have already rebuild disk and reset permissions (all seemed fine) 3 times.
    I've rebooted over 8 times since last night. I cannot use my Mac anymore reliably.
    Please help.

  • My trackpad and keyboard randomly become unresponsive on MBP Retina

    I just got my Macbook Pro with Retina a week ago. Its the newest model that just came out the week I got it. Its a 13 Inch. I noticed when I am using it, the trackpad and kayboard randomly become unresponsive for sometime. I have to close it and wait for it to start working again. Do you have any idea what the problem might be. Should I contact Apple?

    I went through this with my old Late 2008 Macbook Uni when I installed Kingston Value RAM.
    Take your new RAM out - install your old RAM back - do a PRAM reset and see if your keyboard and trackpad are working again.
    Once that's done - turn your Macbook off - install the new RAM - if keyboard and trackpad are unresponsive again - install different brand of RAM.
    I ended up intalling Crucial RAM in mine.
    Good luck.

  • Intermittent keyboard and trackpad freezes in 10.5.2 (not again!)

    Hi all,
    I'm having a major issue with my MacBook Pro built-in keyboard and trackpad. This issue is incredibly reminiscent of the previous widespread keyboard/trackpad freeze problems, documented in a number of threads, such as here:
    http://discussions.apple.com/thread.jspa?messageID=5860606
    http://discussions.apple.com/thread.jspa?threadID=1196400
    http://discussions.apple.com/message.jspa?messageID=6103438
    http://discussions.apple.com/thread.jspa?threadID=1190210&tstart=0
    What's special about this case is that these issues began very recently, well after I installed Mac OS X 10.5.2, which I recall is supposed to provide a fix for exactly this issue. I've never had a problem with this MacBook Pro notebook before, so this is incredibly unnerving.
    The issue is frustratingly intermittent, but frequent. Sometimes the entire keyboard and trackpad locks up (freezes) and won't acknowledge any input whatsoever. Other times the keyboard and/or trackpad appear to get "choppy", sometimes the keyboard will miss a key causing a typo while typing or the trackpad will suddenly stop moving the cursor. Other times the keyboard will repeat keys by accident, causing maaaaajor typos (kind of like that).
    What's really weird is that I'm seeing the floating "eject" bezel appear (the symbol that you see when you hit the keyboard's eject button) very frequently, when my fingers are nowhere near that key and I'm sure it's not pressed. This even happens sometimes when I'm not using the keyboard at all, just the trackpad (most often while scrolling with the two fingers gesture).
    I've troubleshot this in a number ways. Here is one such troubleshooting session's activity log that I kept while performing the troubleshooting:
    ---- CLIP ----
    MacBook Pro Keyboard Freeze problems troubleshooting log
    * Symptoms are a frozen keyboard and trackpad, that is, no input being recognized by the keyboard or trackpad. Not even the light of the caps lock key lights up when the issue is present.
    * Restarted computer. Issue recurred moments after logging back in and beginning to type.
    * Restarting, zapping PRAM. Issue is gone for a little while but has recurred.
    * Found a single line at the time issue began again in the "All Messages" log shown by Console.app that reads as follows:
    4/24/08 Apr 24, 8:58:15 PM kernel USBF: 551. 7 IOUSBCompositeDriver[0x65b7280](IOUSBDevice) GetFullConfigDescriptor(0) returned NULL
    * Restarting computer again, trying to boot in verbose mode. Can't!! Keyboard wasn't recognized even at this stage! Can't log in either, keyboard unresponsive at login screen.
    * Restarting again (via external USB mouse). Login window comes up and keyboard input is acknowledged. Very strange.
    * Keyboard input lost once again after using the keyboard for a short period of time.
    * Restarting, zapping PRAM again, and Logging in as Leopard's "Guest" user to try and isolate issue...no good, just seconds after logging in, the keyboard and trackpad freeze again.
    * Restarting once again, this time everything works. Noticed that the keyboard backlight is not lighting up in low-light situations. Trying to change the light level with the keyboard keys always results in the keyboard backlight bezel showing up with a prohibitory symbol. This is looking more and more like a keyboard driver issue.
    * Repairing disk permissions, no problems reported. Verifying disk itself, no issues reported. Issue persists.
    Observations and Lessons learned:
    * This issue began slowly, with freezes sometimes happening hours apart from one another, however it accelerated quickly. Now sometimes only mere seconds after logging in, my keyboard is frozen and sometimes the keyboard is even frozen at boot time, so that start up modifiers are not even recognized!
    * Zapping PRAM helps, sometimes, but only for a short period of time.
    * No other traditional Mac fix seems to affect the issue (repair permissions, etc.)
    * The issue occurs regardless of whether or not any peripheral devices are attached to the system.
    Perhaps unrelated, but interesting (and new!) to note:
    * The Bluetooth menu item reports that "Bluetooth: Not available", the Bluetooth System Preference pane is not visible, and System Profiler reports that "No information found" about Bluetooth.
    ---- END CLIP ----
    I've yet to try resetting the SMC, or doing a clean install, but from the copious amounts of users who reported similar errors in the threads I linked at the start of this post, those options only sound marginally hopeful.
    Some of these issues (like the weird eject key suddenly firing on its own) have been present for a little under a week, but the freezing is brand new. The only system-wide change I've made in the last week was installed the MacBook Pro EFI Firmware Update 1.5.1, which was successful (verified in System Profiler; my boot ROM version reads as MBP31.0070.B07).
    So mostly I want to know if anyone else using OS X 10.5.2 is also experiencing this problem. Also, though I'm grateful I could actually use my built-in keyboard to type this message (even with occasional missed keyboard presses, GRRR!!!) my only reliable workaround is an external keyboard. Which is a decidedly annoying thing indeed.
    Help?!?
    Thanks!
    -Meitar Moscovitz
    P.S. AUGH! Just as I was typing that last sentence the keyboard froze again! So I'm actually finishing typing this post via a VNC session. So, so, so so frustrating!

    I wanted to post once again with additional information just in case someone else is also having similar problems. Unfortunately, I'm almost certain that this is probably bad firmware or bad hardware, not a software issue at this stage. Here's why.
    KERNEL PANIC! Take a look at the backtrace and you can clearly see that the Trackpad is to blame. Also, in the system configuration report, not the boot ROM version string, which indicates that I have indeed updated to the latest firmware provided by the recent release of MacBook Pro EFI Firmware Update 1.5.1.
    Here's the Kernel Panic log and system configuration I reported to Apple:

  • Keyboard and trackpad freeze after being idle for a few minutes

    I have a early 2008 MBP and just today the keyboard and trackpad freeze after not using it for a few minutes.  I was at work when it happened.  I plugged it in and started doing something else and a few minutes later came back and i couldn't move the mouse or do anything with the keyboard, but processes were still running.  For example, I have a fan speed app that sits in the toolbar, and it was still showing current fan speed.  So I restarted it, and it did it again.  So the next time it happened, I closed the lid and opened it up and it fixed it.  It's happened several times now after a few minutes of non use and I just close the lid and it fixes it.  Also, there was a period when I was using my computer for a couple of hours non stop and it didn't have a problem.  Only when I'm not touching the keyboard or trackpad does it do it.  since this keeps happening i have verified the disk in disk utility, done a hardware reset with cmd+opt+p+r, ran through system profiler to see if there were any problems with no results, and it still does it.  Anyone have any ideas?
    It should be noted that not only does the battery not work for more than about 2 minutes, the left I/O board appears to be dying.  The power chord takes a considerable amount of wiggling and adjusting before it finds a place where it will actually charge. The audio out and the USB on that side are the same way. So I am aware of that problem. Also, I have had to take out the right side fan multiple times and disassemble and oil the bearing because it's going bad, which requires taking the top plate off, but I haven't had to do that for over 6 months. In my mind if the problem was caused by taking the top plate off, that would fry the entire top plate, which happened once when a technitian at a local company took the computer apart for a waranty repair.  All of these problems considered, I don't think they would have anything to do with the fact that the mouse and keyboard suddenly won't work after about 5-10 minutes of sitting idle. I have done nothing different since yesterday that would explain why it does this. 
    Also, I can't do anything with the install disk because the CD drive is dead.  But that's mostly because it was a piece of garbage to begin with.
    Any Ideas would be helpful.

    After doing some more digging I was watching processes in Activity Monitor to see if I could see what process is failing.  I think the problem with with Chrome. It only happened when Chrome was open. And since then I reinstalled it and the problem has so far gone away.  So, I think the problems is solved. 

  • Macbook 13" non-retina keyboard and trackpad freeze

    My macbook pro 13" non-retina is experiencing keyboard and trackpad freezes occasionally. I bought it a week ago and have experienced it 5 times now. The frequency seems to be increasing.

    I just experienced the trackpad and keyboard freezing again. restarted the macbook 3 times. Each time the trackpad and keyboard fails after logging in. This is crazy

  • White Macbook 15" Keyboard and Trackpad Freeze

    I'm hoping someone can help me.  I have a white 15" macbook that is having some issues with the keyboard and trackpad freezing.  Both are completely dead.  When I wiped the machine, during the OS install, it said there was no keyboard attached.  I can only use it by utilizing a bluetooth keyboard and/or usb or wireless mouse.  No other performance issues.  Hardware tests all check out ok.
    This afternoon, my son told me that the keyboard and mouse started working again for about half an hour, then quit again.
    Has anyone else had this issue?  Ideas?  What will this likely cost to fix?
    Oh, and no spilled drinks, drops, etc.
    Thanks...

    As you have determined, this is a hardware issue. We don't know the cause, but it's broken and needs repair.
    Contact Apple using expresslane.apple.com if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.

  • 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 trackpad freeze when left idle after installing hard drive

    Installed a Samsung HM640jj hard drive in my Macbook Pro. Since then the keyboard and trackpad freeze if not in use. As long as I keep scrolling around on the pad everything works fine but as soon as I stop they both freeze. On startup the freezes only last a few seconds but the longer my mac is on the longer the freezes last. I've tried a lot of tricks from other posts but no luck. Not sure if its a glitch with the drive or if I should wipe it and reinstall from OS disk to see if that works. Any ideas? Thanks

    Any chance that something was damaged or loosened while you were replacing the drive?
    What other tricks have you tried? Did you reset the PRAM and/or SMC?

  • Keyboard and trackpad freeze

    Running OS X 10.5.8...my keyboard and trackpad suddenly and unexpectedly became inoperable.
    Plugging in a mouse regained pointability but still could not type.
    Rebooted several times until keyboard "came back".
    Immediately timemachined a backup.
    And now typing this message
    Anybody know what happened? What shoud I do?

    Did the battery get totally drained. Because draining the battery completely can cause it to expand and press on the trackpad and that stuff.

  • Dual 2 GHz PowerPC G5 beachballing and then freezing at random intervals

    My computer at work has been beachballing and then freezing at random intervals for the past week or so.
    What happens is that all processes stop. The cursor is still responsive for a while, and then the application I'm in, regardless of what it is, “beachballs.”
    Occasionally I'm able to wait it out and the computer becomes usable again and other times it just freezes. Then I can't force quit so I have to do a hard power cycle and then start up again. This happens every day, at least 4 times a day.
    I've been keeping the system.log open to look for any tell-tale issues and noticed that during every crash I get the following information:
    3 kernel[0] disk)s3: data underrun
    3 kernel[0]
    and it repeats until the computer becomes responsive again or I decide to do a hard power cycle.
    In addition, I checked the System Profiler diagnostics area and found this:
     Last Run:    11/8/10 1:05 PM
      Result:    Failed
      Failure type:    Memory
      Memory slots:    DIMM6/J43, DIMM7/J44
    So…I switched out the offending bars and switched them for 1 GB bars and this problem was solved.
    The diagnostics result for the Power On Self-Test:
    Last Run: 11/10/10 6:21 PM
    Result: Passed
    However…I'm still experiencing beachballing and freezing problems with the same severity and frequency.
    Help!

    So, to clarify: do you suggest I use Disk Utility first to see if any problems are uncovered? Or should I use TechTool Deluxe instead and test the RAM with Memtest?
    My two cents would be use Disk Utility first. If you don't have the install disk handy, you can do the same thing with single-user mode. See this link for details: http://support.apple.com/kb/TS1417
    You have to run it from single user mode (start with command-S keys held down until you get a Unix terminal screen.
    You can also run memtest from single-user mode, though I do not remember the command syntax offhand. Looking at an AppleJack log, though, I see the following command line entry that was used to run memtest on a three-pass check
    */usr/local/sbin/memtest all 3 -L*
    Running memtest from single-user mode tests more of the RAM because little is occupied by the BSD kernel.
    A snip of the terminal output running memtest:
    Test sequence 1 of 3:
    Stuck Address : ok
    Random Value : ok
    Compare XOR : ok
    Compare SUB : ok
    Compare MUL : ok
    Compare DIV : ok
    Compare OR : ok
    Compare AND : ok
    Sequential Increment: ok
    Solid Bits : ok
    Block Sequential : ok
    Checkerboard : ok
    Bit Spread : ok
    Bit Flip : ok
    Walking Ones : ok
    Walking Zeroes : ok
    Somewhat thorough, though no test is completely bulletproof.

    Book your Apple appointment now, in the mean time you can try a SMC reset.

  • Help! Intermittent Keyboard and Trackpad freeze/unresponsive

    Hi everyone
    I'm pretty new to macs, and got my first one a few weeks ago - 2.4GHz White MB latest model. It has worked well in the first week, but I've experienced some problems with the keyboard and trackpad. At home I usually use a bluetooth keyboard and mouse and they work fine. I usually leave the MB on at night as well. Sometimes when I try use the keyboard and trackpad, it is completely unresponsive. I've also experienced this at uni as well, where it just suddenly freezes. I can only control it with my bluetooth mouse (at uni) and both bluetooth keyboard and mouse at home. This problem used to happen after waking up from sleep as well, where I would open the lid and the keyboard + trackpad is unresponsive. Sometimes when I'm in class and it freezes, I have to hold the power button down and do a power off and on.
    The last time it happened was this morning. My mouse could still function, so I did a normal restart and it just hanged, and the swirly circle icon (not the multi colored ball) just kept spinning. Had to hold the power button down to shut it down and restarted it again.
    Problem is, it seems to be an intermittent problem. I can't seem to reproduce it, so how can I take it to my local shop to get it checked out if i can't show them this problem?
    What do you all recommend?? I really can't afford this to keep happening at random times.
    Also have another complaint with the battery not being flat against the case. It seems to bulge out a bit. I called Apple a couple of weeks ago and they told me to take it to my local reseller where I bought it from (NextByte). I went there and they told me I had to drop it off to them, and it would take 3-5 days for them to take a look, and maybe even longer if they had to get it fixed. I can't afford to be crippled for so many days without my MB as all my uni notes are on it.
    Please let me know what I should do. Thanks!

    Also forgot to mention if I use my bluetooth mouse to turn bluetooth off from the menu, it comes up with a message:
    You cannot control your computer if you turn Bluetooth off at this time as you would lose your input devices.
    Please let me know what I can do. Thanks!
