Macbook Pro Keyboard and Trackpad Not Working

few days ago, my Macbook Pro keyboard and trackpad started to act very oddly.
Basically, the keyboard doesn't work at all. I press down the keys, and all I get is that error message sound. The volume and display brightness keys seem to work, but almost all of the others just won't type anything. it-s like any key command or alt would stay pressed so when i click any key its trying to perform other function instead of just typing the letter. that-s probably the reason why the trackpad is also being very odd. When I first turn on the laptop, it seems to work as normal. I can click on an application, and it opens. But about one minute after the laptop first starts, it's like anywhere I click on the trackpad is a right-click. To open an application, I click like I normally would but instead of opening, a menu pops up as if I right-clicked. This happens in Finder and everywhere else that I've tested (for instance, I can't drag any Finder windows to different positions on the screen, because it acts as if I right-clicked instead of left-clicked), no matter whether I tap or click the trackpad.
I have reset my permissions, but that didn't fix anything. I verified the hard drive and it said there were no problems. A big issue is that I can't do anything that requires me to type in my password, since I can't type anything. I tried to reset the PRAM, but I don't think that it even registered me pressing the Command-Option-P-R keys when I booted up, so i just removed the battery for a while, i am not sure that did anything at all.
i tried to reinstall the os, i had mavericks and i installed a fresh mountain lion but the problem persists. i recently installed virtualbox and the keyboard seems to work right as long as i do not press any of the following keys command, alt, shift, etc.. if i press any of them same thing happens. i found that if i connect a usb keyboard everything works, but when i use the inbuilt keyboard the problem is back and a i have to connect disconnect the usb keyboard to be able to type or use the trackpad normally.
any help would be appreciated.
Thank you.

  • Macbook Pro Keyboard and trackpad not working - SOLUTION!

    Recently my Macbook Pro of 3 years suddenly stopped working -- or at least the keyboard and track pad did. I plugged in an external USB mouse and and keyboard and was able to use it but it was of course cumbersome. Thinking it was a software issue like the one that used to happen to my old G4 desktop I reinstalled the OS but this did nothing but cause a lot of extra work. After doing a lot of hours of research I finally began reading that people were finding a solution by replacing their "topcase" (the topcase includes the keyboard and trackpad). This is a $300 fix and not knowing if it would even work I didn't want to try it and be wrong!
    To make a short story longer I found a website (which I have no affiliation with) called www.powerbookmedic.com who sold the cable only so you could do your own fix for about $35. They provide basic video but not an exact step by step to replace the actual cable -- just how to get to it.
    I will warn you that the components are tiny and I recommend buying the Mac tool kit and pry tool to help you through it. Even so I broke a small component but luckily it still works. In the end I now have a working Macbook Pro and some extra tools for the next time. I stripped a screw so had to spend another $15 and buying anti-static tape, although not necessary might be a good idea. Total cost to me was about $60 with tools and everything.
    It is not very hard to do the replacement but it is tricky because the components are so fragile and I did not have a video to properly describe how to open up connectors -- hence why I broke one. But if you are patient, savy and need to save a few bucks it can be done.
    PS- I have rebuilt desktop Mac's before but this was the first time I ever opened up a laptop. I used the video's provided at http://www.powerbookmedic.com/ as much as allowed.
    Good luck!

  • 10.5.8 MacBook Pro: Keyboard and Trackpad Not Working

    I have an older MacBook Pro (all metal, non-chiclet keyboard) and the trackpad and keyboard have recently become unresponsive. The power buttons work fine and when I plug in a mouse and keyboard via USB, I am able to use the computer-but that limits my mobile usage. Is there a driver update/download that I can get to fix this? Side note: I no longer have the old OS X disc that came with the computer. Thanks in advance for any help!

    Hi s,
    In some cases, the battery can interfere with a cable between it and the inside of the MBP, causing keyboard and/or trackpad issues. Shut down the MBP, disconnect the power adapter, remove the battery, take a piece of something semi-soft (like a paper napkin folded over a couple times), place it over the cable you see in the battery compartment, and tape it down. Replace the battery and see how things go. If this works, you'll eventually want to replace the keyboard/trackpad cable (about $25 if you can do the work yourself). Note that if you go to a repairshop, they usually want to replace the entire top case assembly, which is much more costly.
    If the issue persists, shut down,disconnect the power adapter, remove the battery, connect the power adapter, boot the MBP and see if the issue persists without the battery in place (but remember to save a lot, because if the power adapter gets pulled out the MBP will immediately shut down and any unsaved work will be lost).
    Also look at the battery to see if it has any signs of deformity/bulging, in which case do not use it again (it may be pushing on the keyboard/trackpad cable and causing the issue); it must be replaced.

  • My 2012 Macbook Air Keyboard and Trackpad Not Working

    This all started last weekend when I installed the latest updates from Apple. The reboot and startup went fine, and nothing happened for a couple of hours, but while I was reading on the Kindle app (fullscreen), the trackpad stopped working. The keyboard stopped working too. Only the power button worked.
    Since I received both a Growler and Notification Alert while this was going on, I assume everything else in the background is working just fine, but the keyboard and trackpad simply are not working. I rebooted the machine and it was working just fine. I dismissed it as a one-off occurance.
    However the same issue occured a few hours ago, this time with the Safari screen full-screen. Since I was home, I've added a regular USB keyboard and mice, and that's how I'm typing this out on my Macbook Air at the moment
    Like I said, this all started after I installed the OSX 10.8.4 updates onto my machine. I've never had a prior issue with the keyboard and trackbar until yesterday.
    Any advice?

  • 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.

  • Wireless keyboard and trackpad not working.

    iMac keyboard and trackpad not working after a couple days of not using. Hit power button on them and the light will blink, but will not function. Any help?

  • 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.

  • 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.

  • Macbook pro Late 2011 13.3 inch i7 keyboard and trackpad not working bluetooth showing a cross sign and no usb mouse is detected. Almost dead keyboard and mouse. Earlier same problem used to be solved by opening the lower cover and closing it.

    My macbook pro 13.3 inch i7 late 2011 edition has previously encountered unresponsive trackpad and keyboard. To solve that, I used to open the back cover and then close it. It has been working fine since that. Yesterday, same thing happened, this time I noticed that bluetooth icon is showing a cross sign across it and keyboard and trackpad were unesponsive. After some time , everything worked fine and bluetooth sign was back to normal. Then , suddenly it went back to the problem. I shut it down by holding the power button. When I booted it again, I could not login because keyboard and trackpad were not working. I attached a HP mouse it didnt work. I opened the back cover disconnected the battery and then connected it again, didnt worked. Since then , I have tried many things and nothing has solved the problem.

    @sanjampet
    As you suggested I reset the smc, in the first boot nothing worked. In the second boot, it all worked like a charm. I thought that my problem is resolved now. To test it, I shut it down properly. Next morning, I powered it on, all things i.e, keyboard, trackpad, bluetooth etc. worked and I thought that problem has been solved. When I was just going to visit apple forum to reply you,  the same problem reappeared. A sawtooth cross over bluetooth icon, keyboard not working, trackpad not working,no usb mouse working which worked well when it was fine. I reset smc so many times again and again but same problem continued. Isn't it a problem of the firmware?
    Next time when it will work, I will update its firmware.
    My macbook was bought in dec2011 so no warranty now.

  • My Macbook pro keyboard and trackpad do not work

    There is no water damage. So please, do not say this may be the problem. My mac is only around 2 months old. I was using my keyboard and trackpad fine, when i looked away, and when i looked back nothing worked at all. No keys, nor the trackpad work. Please if someone knows a known issue, please bring it to my attention. Thanks!

  • Keyboard and Trackpad Not Working; Mac OSX Unexpectedly Quit?

    Hey everyone... I think I may need to stop by the Apple store to figure this one out, but I just wanted to make sure if there was anything I could do on my own first.
    So basically, on my MacBook Pro that I got nearly two years ago (late September of 2006) for the past month and a half has had problems. In the beginning, the mouse and keyboard would freeze up and just not work. Restarting the comp did nothing. Some times were worse than others (once it was frozen for 1.5 hours). Then it stopped, every now and then having a few freezes (sometimes when the keyboard froze but the trackpad was still good), but two days ago I had my comp not hooked up to an adapter. When the battery got low, the comp froze. I went to bed and closed the laptop, and the next day it was still frozen. I unfroze it, but then it happened again (I'm pretty sure the same situation... almost no battery)... and it is still frozen, even after multiple restarts.
    Also, during the time when freezes weren't as bad, sometimes the keyboard would get stuck on one key, usually the volume up button (very annoying)... then I was told to restart the comp. When I came back, I was told that Mac OS X had unexpectedly quit.
    Sorry that was a lot to read, but any help is really appreciated! Thanks!
    Not sure if this is also important, but I did spill some water on the keyboard a very long time ago (late December '06)... it wouldn't take this long for that to cause the problem, would it?

    Does booting up in [Safe Mode|http://support.apple.com/kb/HT1455?viewlocale=en_US] help at all? This boot mode checks the disk on startup and disables non-apple start up items and certain kernel extensions.

  • My macbook pro keyboard and trackpad lock up randomly

    In the last day or so, my mac has started locking up the keyboard and trackpad randomly.  It happened to me a couple times yesterday completely at random times.  Once when I was playing a game, and another time when I was just browsing the web.  I had Mavericks 10.9.3 at the time of the first lockup, then updated and the second lockup occurred under 10.9.4.  I have a 15" mid-2012 macbook pro. 

    I have to hard restart the computer by holding down the power button.  Closing the lid like in the issue with the retina mackbooks does nothing. 

  • HELP!: MacBook Pro Keyboard and Trackpad freeze...

    Good Afternoon,
    Yesterday afternoon, I turned on my MacBook Pro and a few seconds after bootup the trackpad became unresponsive, I then tried to perform a restart with the aid of the keyboard however, I then, noticed that my MBP keyboard also became unresponsive. I then tried to turn off the system through the power button and a dialog of OSX came up asking me to Restart, Sleep, and/or Shutdown the computer, meaning that the OS was somewhat responsive. Since I could not select any of the options via keyboard or trackpad I decided to close the lid of my MacBook Pro. Interestly, when I reopened the lid I has to push the power button and the computer went over a new start up sequence and the computer has behaved normally thereafter. However, I should note that this is the second time that my MBP freezes on me in the fashion. What should I do? Is this a common error in MacBook Pros?
    My MacBook Pro model is a 15" Core i5 2.53ghz Mid-2010 with 500GB HDD, 4GB of Ram, and a Nvidia 330m 256mb grapichs card.
    Thank You for any assistance in this matter.

  • Macbook pro (early 2008): Trackpad not working under Windows XP

    My Trackpad worked regularly under Windows (Bootcamp) and Mac OSx until some months ago my Motherboard had to be exchanged because of a fault function of the graphics card. When I started Macintosh after the Macbook pro was repaired the Trackpad worked regularly, but under windows the mouse didn't react to moving the finger or clicking. I reinstalled the drivers, but this didn't fix the problem.
    What shall i do now? Thank you for any advices.

    since my mac is year and two months old (funny, two months and you are screwed).
    Not if you had of purchased Apple Care.  You would have been covered for 3 years.
    What I would like to say to the Apple:
    This is not the place as Apple does not come to these forums. 
    These are user-to-user forums where everyday folk post "technical" questions and offer answers to each other voluntarily.  No one here works for Apple nor does Apple get involved in responding.  Not even sure if they "lurk."

  • Macbook Pro Keyboard shortcuts are not working

    Hi there,
    In the last week or so my keyboard shortcuts for volume control are no longer working - even the mute button has no effect. when I press the shortcuts the volume adjustment image pops up and the computer makes the clicking noise, but the volume doesn't change. I can change it by going into system preferences>audio but it's fairly annoying. Would really appreciate some help on how to solve this! Thanks

    This solution worked for me! I have a MacBook Pro OS X Yosemite 10.10.1; after new software download I had to rely on earbuds or external speakers. Weird solution, but it worked, so thanks for sharing!
