Internal Keyboard frequently stops working

We have a new (2 week old, purchased from Apple as Refurbished) Powerbook G4/1.67/15" with a keyboard that isn't operating correctly. Every once in a while, perhaps once or twice a day - a number of the keys (at random - not always the same ones) stop working and the remaining functioning ones produce the wrong characters. The number lock key is not on. Periodically, the user can't access his account as the keyboard does not produce the correct characters. When this happens, we use an external USB keyboard, which works.
We suspect it might possibly be the result of a poor internal connection somewhere between the keyboard and the motherboard.
Has anyone any other suggestions?
Powerbook G4/1.67   Mac OS X (10.4.7)  

Hi Andrew, I have the same problem with my older seventeen <can't type even numbers> inch PB after a repair. As for now I browsed through this forum and discovered that it might be a connection problem of the cable of the keyboard. If you want to repair it yourself, you might checkout www.ifixit.com, which gives you excellent explaination on how to open different parts of you PB. I did not start with mine yet, but will do as soon as I hove an undisturbed afternoon. If you find out something else, please drop me a mail to.

  • Wacom Tablet causes Apple wireless keyboard to stop working.

    My Wacom tablet/pen causes my Apple wireless keyboard to stop working.  While working on a photo in Photoshop using my Apple (usb) mouse to make selections the keyboard works fine.  When I use the Wacom Pen to make selections, not immediately but anywhere from five to ten minutes into it, I hear what sounds like a chirp from my computer (Mac Pro) and my keyboard stops working.  The command, option, control and direction keys still work but not the number and letter keys.  I have to connect a spare Logitech keyboard via USB in order to continue and not loose my work.  After awhile I will hear the chirp again and the Apple keyboard will start working.  This will continue to occur at irregular intervals.  Without the spare keyboard I've had to reboot my computer (loosing all the work on the photo) to get the keyboard working again, but only for it to reoccur.  Any suggestions to fix this would be appreciated.

    The Mac inherently keeps all input methods active, such that you could type alternate keys on alternate keyboards.
    If you have third party add-ons that might change the way Bluetooth works, those would be the primary suspects.
    Be sure all your Drivers are completely up-to-date, and batteries in battery-powered devices are still strong.
    Bluetooth uses the same part of the frequency spectrum (but a different modulation technique) as cheap WiFi Routers, baby monitors, and microwave ovens. if you live in a busy apartment building, there may be very high levels of interference.

  • Keyboard shortcuts stopped working after upgrading to iOS 7

    Does anyone know how to make the keyboard shortcuts start working again in iOS 8? After I upgraded to I OS 8 on my iPad air, the keyboard shortcut stopped working. Is there anyone who knows how to make this work again? All the fixes online pertain to iOS 7 and earlier, and they're not applicable for iOS 8.
    Hope someone can help!
    Thanks!

    I lost all my keyboard shortcuts on my iPhone 5s after upgrading to iOS 8. They still showed up on my iPad Air (iOS 8) and iMac (10.9.5). There were, however, massive sync problems, sometimes they would only flow from one device to all the others, sometimes from one device to only one of the other two, sometimes not at all.
    I deleted all my shortcuts and started from scratch, deleting “~/Library/Application Support/Ubiquity”, ~/Library/Dictionaries” and “~/Library/Mobile Documents/com~apple~TextInput” from the iMac and KeyboardDomain from my iOS devices.
    Rebooted everything a dozen times.
    Toggled Documents & Data Sync off and on a dozen times too in all kinds of combination with rebooting and deleting the aforementioned files.
    Everything always starts working and syncing fine for a very short while, but sooner or later one of my devices stops receiving new shortcuts as I re-add them.
    I reboot that device and it catches up. I enter new shortcuts, and that device doesn’t get any new shortcuts. This time, a reboot doesn’t fix anything.
    After using my devices for a while, I notice shortcuts are entirely gone from both the iPhone and iPad, but not from the iMac.
    I even upgraded my iPhone 5s to a 6, and right off the bat it had issues with keyboard shortcut sync. I also setup my iPad as new, and same thing: right off the bat, sync issues with keyboard shortcuts.

  • My keyboard has stopped working. How do I fix it?

    Hello!
    Today I got back to work after my summer vacation and for some reason my keyboard has stopped working.
    I tried with my collegues keyboard but that didn't work either.
    The keyboard works if I give my virtual machine in Parallels direct access to it, but not in OSX so it's probably not a hardware issue. (This is how I am writing this)
    The caps-lock light works even when connected to osx. Mouse works perfectly in osx.
    I am running 10.6.8 on a Mac Pro 2x2.8ghz xeon 12gb RAM.
    Any ideas?
    Thanks a bunch!
    /Hannes

    I upgraded to Mountainlion and the problem not only persisted, but also worsened.
    Any button I pressed, it restarted.
    I have removed a couple of apps I had installed, for example Double Command which I think might have been the culprit, and now the computer works fine again.
    Big relief!

  • HT2452 my imac keyboard has stopped working? help!!!

    my imac keyboard has stopped working??? help!!!!!

    My keyboard just stopped working out of the clear. One minuet OK next it was dead. No little green light at all. New batteries did not help.
    FIXED THE PROBLEM!  I took a small piece of aluminum, made a little ball out of it and dropped it down the tube where the batteries go. Replaced the batteries I had just used......little green light comes on and the the keyboard functions like always.
    My guess is after a few years the contacts oxidize a bit and don't make contact with the batteries on the bottom of the tube. Give it a try.

  • Camera switching keyboard shortcuts stopped working

    I'm working on a multicam sequence, and I can switch cameras by clicking on the different shots in multicam view, but using the 1, 2, and 3 keys on the keyboard no longer switches the camera while I'm playing through.
    I've tried changing the shortcuts to different keys, but that didn't fix anything.
    Anybody else run into this issue?
    I feel like it's probably a toggle I inadvertently hit somewhere, but I have no idea how it happened.

    Thanks for the quick reply, but unfortunately I don't think that solves it.
    If I have the multicam sequence paused, and have the clip selected on the timeline, I can switch between camera angles with no problem.
    However, as soon as I start playing the sequence in the multicam monitor, the keyboard shortcuts stop working.
    Also, the only keyboard layout I have installed is US English.

  • The "enter" key on the numeric keypad of my external mac keyboard has stopped working. Help!

    The "enter" key on the numeric keypad of my external mac keyboard has stopped working with my Macbook pro.  If I plug the keyboard into any other computer, that entier key works fine. I'm using a standard Mac wired keyboard, & it's worked fine for 2 years now. Help!
    This is the keyboard I am using: http://store.apple.com/us/product/MB110LL/B/apple-keyboard-with-numeric-keypad
    Not sure what I might have accidentily done to disable the enter key. (The normal enter key works fine, just the one on the numeric keypad.)
    Thank you for your help.

    Hi there,
    Do you have any resolution to this problem in the end? Because it happened to me an exact same thing.
    Please share if you have found a solution to your problem. I also cannot think of what I did wrong to disable the Enter key.
    Best Regards,

  • Usb keyboard keys stop working after 10 minutes on mac mini osx lion

    I am using a mid-2010 mac mini with opitical drive, updated to OS X Lion. Within the last two days I noticed a certain section of my wired keyboard eventually stops working. These are the right arrow key, as well as the 1, 2, 3, zero, period and enter keys. The virtual on-screen keyboard works just fine. I've come home from work and powered the mac and all keys work fine for ten minutes so it can't be that the keys are worn. I was going to take it to Apple Store genius bar but now I can't tell if it's the hardware or the lion software that's buggy.

    I had terrible problems last year with the USB ports on my 20" display. They were made worse when I installed a USB 2.0 PCI card in my G5.
    At the time the advice I got was that I should avoid using the display as a USB hub. Apparently the ports are only intended for devices relating to the display (whatever that means). Ridiculous if you ask me. I succesfully use my Cubase SX dongle in the back of the display but that's all.

  • Internal speakers have stopped working (Lenovo W500 with Win 7 Pro)

    Hi
    I have a Lenovo W500 4062-5YG... O/S: Win 7 Pro
    My sound device is a Conexant 20561 SmartAudio HD.
    The problem is, that the internal speakers have stopped working all of a sudden... I think it is a hardware problem since when I hookup external speakers or headphones they produce sound... but I am no expert!
    I have done the following to try and fix it:
    Disable, then enable audio drivers
    Uinstall, then install audio drivers
    Setting the internal speakers as the default speaker source
    Restoring the system to an earlier day (where I knew that the speakers had functioned)
    None of these actions have worked.
    I actually thought I could perform a hardware test on the speakers in the "Lenovo Solution Center"... but it doesn't seem like it:-(
    So...
    How can I know for sure whether it is a hardware or software problem?
    And more importantly - How can I get my internal speakers to work?
    Any help is appreciated.
    Cheers
    Philip

  • My keyboard has stopped working on my iMac I bought a new keyboard and still not working any ideas?

    MY keyboard has stopped working on my iMac I bought a brand new one and the keys work but the volume buttons do not operate the volume I've changed it twice now and the same thing is still happening

    What is the make & model number of the keyboard?
    You could get a keyboard remapping program & map someother key to the volumn key.
    There is a list of them in this thread.

  • Keyboard shortcuts stopped working PS v11.0.2 Win7

      argh. The keyboard shortcuts stopped working a few weeks ago and I've been trying so many fixes that worked for others, but none work for me.
    Photoshop v11.0.2
    Windows 7
    Dell Laptop Studio 1555
    I periodically reset my prefereces - it does nothing to change the fact that the keyboard shorts don't work.
    I've done a system restore to a date before this issue began. Nope, didn't work.
    Not one of the shortcuts work. Not open, not close, not transform, not save,  not cut, not copy, not paste.....  This is incredibly frustrating in addition to wasting time because I STILL (lol) try to use the shortcuts. I've used them since 1991 and it's ingrained in me.
    Please, I hope someone has a remedy.  As I research, I see more and more people having this problem.

    You can always try mapping your own key's. If you insist..

    Honestly, unless you need the NUM-Padd there are a lot of manufactures out there that make great wired/wireless keyboards that will support OS X out of the box. You can buy them at 7-11 I hear.
    It's up to you, hears a little something to read from Microsoft, since your a noobie.

  • The top row of my iPhone 3GS keyboard has stopped working.

    The top row of my iPhone 3GS keyboard has stopped working. I've already done a soft reset, hard reset, and restored it to a new device. What else can I do?

    When you are using other applications, or just on the home screen, does that area of the screen respond to touch?
    Steps to resolve issue (I understand you have done what you have but it's always good to try again):
    Clean the iPhone screen with the cleaning cloth that came in the box with the iPhone.
    Do not wear gloves while using the touchscreen. Do not use the touchscreen with wet hands or immediately after applying hand lotion. Moisture affects touchscreen behavior in the same manner as it affects a trackpad.
    If you have a protective plastic sheet or film on the touchscreen, try removing it because it may be preventing the touchscreen from working properly.
    The current application may not be responding (frozen), press and hold the Home button below the screen for a least six seconds, until the application you were using quits.
    If that doesn't work, turn the iPhone off and turn it on again. Press and hold the Sleep/Wake button on the top of the iPhone for few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
    If that doesn't work, reset the iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
    If the steps above don't resolve your issue, please schedule a service appointment with an Apple Retail Store for evaluation and replacement, if necessary, even if your iPhone is out of warranty. If an Apple Retail store is not an option, contact Apple to find out your best service option or see the iPhone Service FAQ.
    Tip: If you are going to take your iPhone into a Apple Retail Store for evaluation, follow these steps to help the Mac Genius understand where your touch screen is experiencing unresponsiveness.
    Open the basic calculator application to test all but the top row of the screen. Press each button on the calculator and verify activity.
    To test the area at the top of the screen, rotate the iPhone to change to the scientific calculator and press all the buttons in the left two rows. (An original iPhone must have iPhone 2.0 software installed to access the scientific calculator feature.)
    To test the touchscreen function at the top of the screen of an original iPhone without the iPhone 2.0 software, press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. If the slider does slide, press and hold the Sleep/Wake button until the Apple logo appears to turn iPhone on again.
