I have Late 2011 Macbook Pro and zxcv keys are not working?

I have late 2011 Macbook Pro and the zxcv keys are no longer working. Once I connect USB keyboard I can utilize these keys. Do anyone have solution?

How did you try to use Acitivty Monitor?
Open Activity Monitor, choose "All processes" from the list, and sort processes by CPU usage. More likely than not, there will be task using up good bit of CPU.
You could also try resetting SMC:

    Hi,
    While this could be a hardware issue, it's always worth trying the following.
    Open windows Control Panel, open Device Manager, expand Keyboards, right click the entry 'Standard PS/2 Keyboard' and select Uninstall.
    Shutdown the notebook.
    Then unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.
    Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    Regards,
    DP-K

    my zero and nine key are not working and also //////// symbol sometimes keeps repeating

    Try an external keyboard. If it works, you need a new internal keyboard.

  • I have a late 2011 macbook pro and it wont update the firmware to 2.7, it downloads the update then says its installing it but when i go back to software update it keeps coming up saying it needs to be updated

    I have a late 2011 macbook pro running OSX Lion, and it wont update the firmware to 2.7, it downloads the update then says its installing it but when i go back to software update it keeps coming up saying it needs to be updated. Im wondering what can i do to stop this or get it to update.

    Once it is downloaded you need to restart the computer if it does not restart automatically. When it next starts up you should note a progress bar appearing below the Apple logo. When done the computer will restart once more. The new firmware should now be installed.

  • 13-inch, Late 2011 Macbook Pro and Thunderbold Display...

    Hello Dear Users,
    First I wish you have a nice new year with full of health, happiness and wealth, then i am asking my question:
    I am using a 13-inch, Late 2011 MacBook Pro having
    Processor  2,8 GHz Intel Core i7 2 cores+2 HTs
    Memory  16 GB 1333 MHz DDR3
    Graphics  Intel HD Graphics 3000 512 MB
    Software  OS X 10.9.1 (13B42)
    specifications, setup with double Thunderbold Displays.
    I sometimes feel that mac's display performance is marvelous and sometimes I feel like I am looking at an old school, blury screen. Is there anybody feels like I feel. I have doubts about screen performance. Well I searched on internet before to write but I could not express what I feel on google search for example. So, I am writing here what I feel. Sorry for my English if I could not express what I meant.
    Thak you, and have a nice new year.....

    I've been having the exact same issue, same monitor and same laptop.  I spoke to a couple Apple techs on the phone and took my mbp to a genius bar last night, thinking it might be a video card issue since the blocks were also showing up on my macbook's screen. It of course failed to replicate at the store, even with a TB display hooked up.
    After this I finally realized it was an issue with the monitor and not the laptop, since it only happened when they were connected (duh... I never checked with them disconnected)
    I was able to make it go away temporarily by pushing the cables on the back of the display firmly in, but a few hours later I noticed a couple blocks popping up again.. however it wasn't as bad as before.  Seems to me it must be some issue with the hardwired power/tb connetor.

  • Purchased a used Late 2011 Macbook Pro and cannot get find my Mac to work. What do I need to do?

    So I purchased a used late 2011 Macbook Pro from a friend. I am trying to get the find my Mac app set up but it won't let me because I believe he still has it as one of his devices. I texted him a couple days ago to ask him to remove it, but it doesn't seem he has or is in any rush to do that. I was debating re-installing the entire OS to give myself a fresh start. Will this give me the ability to set my computer up on the find my Mac app or is it tied to something more than the hard drive/OS.

    I actually think I will be upgrading the hard drive size. So to confirm, when I reinstall the OS on this new hard drive, I will be able to add this as my own device within the Find my Mac app?
    Yes, after you zero out the drive. 
    Which os is installed?
    Just out of curiousity, what happens on my friends end to this device?
    It's your friends problem not yours.  Your friend will have to get his "Find my Mac" app.

  • Can not shut down late 2011 MacBook Pro and turn it back on again without the hard drive disappearing?

    Ok, I have searched for months for an answer to this question to no avail, probably because no one has experienced it before. I am hoping however that you guys can help me figure this one out cause it is driving me nuts! Also, I am not entirely sure what section of the support I should put this under so if I stick it in the wrong place, I apologize.
    Right now my problem is very simple. When I turn off my laptop, and then try to turn it back on, my internal hard drive disappears... and I get the blinking folder with a question mark on it. I have figured out something interesting however. I have an install disk with Ubuntu Linux on it. If I boot into that first, then RESTART the laptop, not shut down and turn back on, it reads the internal hard drive just fine and I can boot as if there is nothing wrong.
    Second part to the problem... If I allow the laptop in either OSX or Windows to go to sleep (aka shut off the hard drive but the computer remains on), when I attempt to wake it up, I am greeted with the usual log in screen of whichever OS I am in, but is frozen and after a few seconds goes black and restarts the computer to find that... Surprise! The hard drive is gone
    I have tried every trick in the book that I can think of, but can not seem to come up with a solution to the problem... I know when the problem happened and if anyone thinks that that will help them figure this out I will type everything I did up till, including the crash that caused this, and my attempted fixes, but I have class right now so only if you guys want it I will type all that out.
    What I am currently running is:
    2011 MacBook Pro 13in screen
    4Gb of Ram
    1TB internal Hard Drive
    OSX 10.11.whatever the newest update is... just updated the other day again.
    Windows 8.1 on BootCamp 5 (yea I know its not supposed to work but it does) again, fully updated
    Ubuntu 13.10 (I think? Doesn't really matter, its just an install disk I use to boot the computer)
    If there is anything else that you guys need me to provide, I can, just simply ask. I can provide as much info as is necessary.

    Sorry it took me so long to write back, But unfortunately this didn't help my issue.
    My uncle and I did a lot of tests on this computer and have narrowed down the location of the problem a little bit.
    We tried to first reset the SMC and the NVRAM as suggested, but the only thing that did was make the fans run on full tilt for the first session after restarting it for some reason. After that we tried re installing OSX over the OSX that was already on the system (not removing any of the files). This also didn't do anything but make refit stop working. Then we moved onto the next task at hand by removing the hard drive entirely and booting it as an external drive from one of the USB ports... as long as you booted it with the options key held down, it worked perfectly fine. Then we put an alternative hard drive into the computer and installed OSX on that. This time there was no trouble booting anything up. Everything seemed to work flawlessly. So we made a backup of my original drive (OSX, Windows, and all) onto an external hard drive and tested booting to it via USB. That again worked perfectly fine and booted right up with no problems. So after that we formatted the original hard drive and reinstated OSX. We then proceeded to transfer all the old files from the backup onto this new installation and LOW AND BEHOLD..... we were back to square one with it refusing to recognize the hard drive again.
    So this basically told us that there appears to be something either wrong with the hard drive, or something got really screwed up in the software along the lines and by me copying all my old files back over, I just ended up bringing the screwed up file back over with it! (despite not copying over any settings of any kind) So I am still extremely confused as to what is going wrong... did some boot sector possibly get screwed up may be?

  • I have a 2011 MacBook Pro and installed Mountain Lion recently and I want to uninstall it to my old software how do I do that?

    Please help me out I really don't like the Mountain Lion software, the old one i had was much better and I can't seem to figure out how to get back to the one I use to have.

    if you plan on doing an internet recovery install of your old os which is Lion - keep in mind that everything will be erased in your hard drive.  your files are gone - unless you have made copies of them in another drive.
    you will have to reinstall everything over again.  if you're prepared to do that, then click on the link below to learn on how to start internet recovery since booting through your recovery partition will reinstall Mountaln Lion.
    Force Lion to Start Internet Recovery.
    Now, if you have a early 2011 Macbook Pro - then it came with Snow Leopard - use your install disk to reinstall.

  • I have a 2011 MacBook Pro and the battery has died what kind of battery do I need?

    What kind or battery does my late model 2011 MacBook Pro need?

    The one that your Apple Store or your Apple Authorized Service Provider will install. MBPs from 2010 on forward do not come with user-replaceable batteries and special tools are needed to remove the one within. Plus whatever one you get outside of the official channel will cost the same if new, so there is no sense in going solo on this.

  • I wiped down the touch pad on my MacBook Pro and now it's not working well

    I wiped down the touch pad with a damp cloth on my MacBook Pro and not it's not working very well.  What should I do to fix the problem?

    Let it dry, it will come around. You just chilled it a little most likely, unless the cloth was very damp....
    Next time use rubbing alcohol.
    It removes the oils and grease and dries fast too.
    So your have appy to the cloth, wipe, flip the cloth and wipe up the dirt and grime, then start the process with a new clean section of cloth, else you place the grime back on.

  • MacBook Pro up arrow key does not work how to fix it?

    When I am just working on the computer the up arrow key does not work at all but when I use bootcamp to go to the PC side the arrow works so i know its not a phisical problem, i have tryed everything i know and still no success.

    Hello brooklinekilla,
    I would be concerned too the up arrow key on my keyboard was not working.  I found an article that can assist with further isolating and troubleshooting issues with the built in keyboard.  I recommend following the steps under the section titled, "Some keys don't work as expected" in the following article:
    One or more keys on the keyboard do not respond

  • Satellite C50-A-15Q - arrow, question mark key and z key are not working

    I have a Satellite Pro, C50-A-15Q. All keys were working fine yesterday, today I turn the laptop on and the arrow keys, question mark key and z key are all not responding. Any idea how I can fix this?
    I have tried turning the laptop off and on, hoping (naively) that this would fix, but to no avail.

    As Tom already wrote, it is not easy to say for sure if this malfunction is result of defective keyboard or maybe keyboard controller. In my opinion troublemaker is the keyboard itself.
    Have you maybe updated BIOS or done anything that could be responsible for this?
    I presume your notebook is pretty new model with valid warranty so best option for you is to contact nearest Toshiba service provider and ask for help.
