Keyboard will not work properly

Only some keys function properly. No alphabet keys works and only 5 number keys. Mute works, volume does not. Scroll arrows do not work, but caps lock does, and so on. Late 2008 MBPro

Sounds like you have a bad keyboard or keyboard cable or a bad connection between that cable and the logic board. It does not sound as though your problem could be software-based.
If you have access to an external USB keyboard you could plug in and test with, that should tell the tale. If it works OK, you have a hardware problem.

    Fast answers:
    1. Try resetting NVRAM/PRAM and SMC. Doesn't usually 'cure' keyboard problems you report, but it costs nothing and only takes a few minutes.
    https://discussions.apple.com/thread/3819550?start=0&tstart=0
    2. Try plugging in a USB keyboard. Doesn't absolutely have to be a Mac keyboard. A PC keyboard will work for a test. If the typing problem does not occur with the USB keyboard, you have a temporary solution until you can arrange to visit a repair facility.
    3. If your MacBook is older and has a user-removable battery, shut down the computer, remove the battery, and examine it for signs of 'bulging' or swelling. Then connect the computer to the Magsafe power supply, without reinstalling the battery, and turn it back on. If the keyboard problem has gone away, it was likely caused by a swelling battery.

  • Keyboard will not work

    My keyboard will not work. Last night I was using my computer and my battery died so I plugged it in and went to bed. This morning I turn my computer on and my login page appears but my keyboard and mouse will not work.

    It sounds like what I have seen multiple times on a device with moisture damage.
    Even sitting on a bathroom counter during a hot steamy shower or bath can cause keyboard and trackball problems UNTIL properly dried out.
    It really is more common than you think.
    1. Remove the battery immediately!! Do not attempt to turn on your BlackBerry.
    2. Let the device dry in a warm, dry place for 3 to 5 days* (see below)
    3. DO NOT "check it each day" by placing the battery in. Leave it be to dry completely. This takes time. Replacing the battery to check it can only damage it more (moisture + electrical current = disaster).
    3. If the device is warm after the drying period, allow it to cool to room temperature before placing the battery back in.
    *Suggestions on drying your BlackBerry in a warm place (open, with the battery out):
    Place the BB in a container of dry UNcooked rice, and then you might also place it in any of the locations mentioned below.
    On top of any dry heat emitting electronic component: TV cabinet or CRT, LCD, cable TV/Satellite converter box or plasma monitor
    On the dashboard of your car on a sunny day

  • My keyboard is not working properly. To get an a i have to type a q

    my keyboard is not working properly. To get an a i have to type a q. To get a w I must type a z. M is the semicolon. Period is less than sign. I have turned off the computer and unplugged the keyboard and it still does not work. Running OS 10.6.8  Just noticed I have to use caps to get numbers.

    Somehow I had gotten my keyboard preference changed to French.
    If you have more than one keyboard layout enabled (checkmarked in the Input Sources section of the Language & Text control pane in System Preferences), then pressing Command-Spacebar or Command-Option-Spacebar will switch the active layout from one to the next.
    You can prevent that from happening by either -
    • Reducing the number of enabled keyboard layouts to one; or
    • Turn off those two keyboard shortcuts. You can do that in Syatem Preferences > Keyboard > Keyboard Shortcuts; click the Keyboard & Text Input in the left pane, then uncheck the two "select" items in the right pane.

  • Keyboard issue I have a iMac thats about 4 years old, and now the keyboard is not working properly. some keys do not work. Any suggestions ?

    I think I may have a virus! My keyboard is not working properly. When I press the zero key, it doesn't appear. Other keys that do not work include the directional keys, delete key, and others. I tried everything that I can think of to fix it, but nothing sesems to be working. Should I bring the keyboard and=/or the entire computer into my local Apple store+? see, the +? appears before the question mark, and I didn't put it there! Thanks!

    No need to take the computer at this stage.   Just take the keyboard into your local Apple store for examination.   If you have another machine, not necessarily Apple, you could try the board on that or perhaps a friend's machine … they are largely universal.
    You do not have a virus.

  • My Macbook Pro keyboard AND USB keyboard will not work.  However, the trackpad and USB mouse will work.  Any help?

    My Macbook Pro keyboard and USB keyboard will not work.  However, the trackpad and USB mouse will work.  Any help?
    This is quite frustrating, since it randomly occured as I was browsing the web.  It seemed to happen out of nowhere.  I cannot login to my user account because I cannot type my password. 
    Any help will be appreciated.

    If you have another Mac, boot the non-working one into Target Disk Mode (holding down "T" at startup). Hook up the two Macs via a Firewire cable. The non-working one will mount on the other Mac as an external Firewire HD.
    Next, download the 10.5.6 Combo update from here:
    http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1056comboupdate .html
    Run it. When it asks you for a destination, choose the other Mac that was mounted via Firewire. When it's done, unmount the computer and restart it. The keyboard and mouse should work now.

  • Touchsmart 520-1047c Mouse and Keyboard will not work after sleep mode

    I have an issue which I need some help with. When my computer goes to sleep the wireless mouse and keyboard will not work unless I restart, however each one will wake the system up but will not operate after that. I have tried just making the display go to sleep, both go to sleep but that makes no difference same issue occurs. The only work around I have found is going into the power settings and turning the sleep mode off for booth the computer and display. This does not solve the problem it just masks it. New batteries, unplugged and replugged the dongle, updated the bios and all drivers. Don't know what else to try. Anybody know how to fix this? Thank you in advance for your help.

    Hello Anonymous.
    Although possibly not related to your problem, I will remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].
    As for your problem, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.

  • HT1349 my home button will not work properly... I have to hold it down several times for it to go to the home screen

    my home button will not work properly... I have to hold it down several times for it to go to the home screen

    I would try a restore just to see if it could be something software related, but if that doesn't work I would recommend taking to an Apple Store to see if it is a serious hardware issue and if it is, assuming you're in warranty, then they would be able to replace your phone.

  • My garage band will not work properly with new lion upgrade..HELP

    My garage band will not work properly with new lion upgrade..HELP
    I have tried to open old session i have done in garage band and many of the effects and instruments I have used will not show up. The system seems to have a bug.

    If the graphical user interface looks broken, that is quite often a problem of corrupted user preferences - have you tried to remove the preferences file, as described in the FAQ
    http://www.bulletsandbones.com/GB/FAQPages/OddBallProbs.html
    Here is again the short version:
    Quit GarageBand, if it is running.
    Open your User Library in the Finder. It is hidden in MacOS X Lion, so use the Finder's "Go" menu:
    Finder > GO    hold down the "Options" key, until the library appears in the menu, select it.
    In the window that opens, open the folder "Preferences" and remove the file:com.apple.garageband.plist and com.apple.garageband.plist.lockfile
    Then try again to run GarageBand and download the loops.
    The preferences file stores all you user settings that you set using the "Preferences" panel in GarageBand, also the layout of the GarageBand window and the location of your recent projects. You will have to enter these settings again after removing the file.
    Regards

  • HP computer will not work properly with an HP printer

    I have the following two items that I am trying to use together:
     - HP 23" TouchSmart Desktop, T6500 2.1GHz 4GB DDR3, 500GB HDD (Windows 7)
     - HP OfficeJet 6500 Multi-Function Printer/Scanner/Fax
    When I try to scan to Adobe Acrobat Professional 9.0, the document goes through the scanner, however the dialog box that I would expect (e.g. "Next Page" or "Done") never shows up.  At this point, the system is unresponsive with respect to Adobe or the printer.
    I suspect that it is waiting for the input from the dialog box that never showed up.  I tried to move the other windows to see if the dialog opened in the background, however I am not able to select any of them (they remain frozen).
    I contacted HP Support, only to have them tell me it must be the driver, and I have an "old" printer.  (I did not realize that a 9 month old printer was considered "old").  I have tried all of the possible drivers that are available (original disk, downloads, other downloads from HP tech support), none of these resolves the problem.
    In any case, they were unable to resolve the problem of having an HP computer work properly with an HP printer.  (The printing function seems to work, just very slowly).
    Has anyone else heard of this?  Is there a resolution?

    Update: I am still looking for a solution to this problem - the scanning portion of the Multi-function OfficeJet 6500 does not work properly with the HP TouchSmart computer.
    I have not been able to find anyone in HP that can tell me when (or if) new drivers will be released for this printer.
    I decided to investigate upgrading to a newer version of printer since HP told me the 9 month old printer I have was "obsolete", only to find that the identical printer is still on sale in many stores.  Hmmm....
    I feel like I am getting the run-around from HP.
    I have since tried several more driver/software combinations, but every time I have the same problem (as described in the previous post).
    If anyone has any ideas or suggestions, I would be most happy to hear them.
    Thank you.
