Random keys on keyboard malfunction.

Its been about three days since the problem first presented itself. Using my USB keyboard random keys such as ", w,3, num lock 5 key, capital p, and the right arrow key. I am using the on-screen keyboard to help me write this post.
Things I have tried (according to research via google):
Trying a different keyboard. Same problem, temporary fix for roughly thirty minutes.
Trying a different USB port (front and back). Failed.
Uninstalling keyboards on device manager. Rebooting, failed.
Ease of access, keyboard shortcuts, sticky keys, filters. All of that now unchecked and failed.
Turning computer off, holding power button down for 10 seconds
Computer specs:
Windows 7 Home premium 64 bit.
AMD phenom II X4 945 Processor
8GB RAM
AMD RADEON HD 5450
Keyboard: Steelseries Shift
Mouse: Razer Deathadder
Sidenote/story: I modified my Razer Deathadders lights on the razer logo and scrollwheel to have them off. As soon as I turned them back on my keyboard started working just fine. Then shortly after five minutes it went back to having problems.

Because you mentioned in the sidenote/story that you adjusted the settings for your Razer Deathadder and had success for a few minutes,  have you thought to, perhaps, uninstall the software to see if the issue goes away permanently?  I don't know of any reason that it would have conflicts with anything else on your computer, but it might be an interesting troubleshooting step to try.  Other than that suggestion, I wouldn't know where to go with this...
Good luck, I wish you the best with this.

  • Cat hit random keys on keyboard

    I have a 2007 iMac running an up-to-date version of snow leopard. This evening, my cat ran across my keyboard, hitting who knows what keys. Now my iMac behaves as if it perpetually zoomed in. Control '0' does not work, and neither does control 'Z'. According to System Preferences, my screen resolution is still 1680x1050. I rebooted without success. The login screen was standard resolution, but after that, everything else is magnified at least 2X. The nearest Genius Bar is 75 miles and at least one blizzard removed. Any assistance would be appreciated.
    Nevermind. In the System Preferences, when I went to 'Universal Access', I was able to find out that that 'control 8' was systemspeak for 'zoom in'. Once that was de-selected, my system returned to normal. I thought only windows boxes did random screen resolution changes...

    Hello Anthony,
    This is one of those rare occasions when you could mark the post as 'solved'.   You won't get any points for yourself but it will tell other people that a solution has been found if anyone has the same problem.  (Albeit the cat will be different).

  • U150 keyboard malfunction after changing screen, = repeating, few numbers not working

    Hi!
    I changed my cracked U150 screen on my own (warranty is passed).  I thought it worked fine on test boot before attaching the bezel.  I aborted the test boot (as the instruction video said to do), and put on the bezel with some difficulty (it's a tight fit on the bottom of the screen around the hinges).
    The next boot up failed, which I've never seen before. Got a bit worried, as it wanted me to try recovering to a set point (several weeks prior).  Opted to just turn off and back on, and it seemed to work...EXCEPT now a few keys on the keyboard malfunction.  Esc, `, 5, 6, 0, ) and Delete all type their character and then immediately type an = which repeats.  The actual = button does nothing: types nothing.  In caps, the keys do the same thing, but of course type a + which repeats.  F5 also does it, and I'm not sure about other F keys because I don't want to do some function that will shut down my typing right now! 
    U15============ 0========= )+===========  When I press any other key, the repeating equals stops, of course...
    When I boot up, the computer beeps repeatedly as if a key is repeating in error, so something in startup must use one of those keys and causes the same issue: since I don't actually press any key on bootup, does that indicate it's more of a software problem than a hardware problem?
    I've taken off the screen bezel again (a real pain and not a good repeated activity because I typically break one tiny plastic clip each time no matter how careful I am) and no change. I see no keyboard cable anywhere near the screen or cover or hinges-just WLAN cables and the camera. I did not spill anything on the keyboard and it worked totally fine until I replaced the screen. Online info about Lenovo S or Y series seems to show the keyboard cable down low, so again, not near the screen.  The screen website (laptopscreen.com) folks had nothing to say that helped. My search online shows nobody with a similar experience. 
    There is no Lenovo keyboard driver on the Lenovo site, so I don't see that uninstalling and reinstalling the driver would make a difference: besides, how do I reinstall a keyboard driver if I can't use the keyboard once I've uninstalled it?  Is the mousepad enough to reinstall?
    So, I would be ever ever so grateful for any help/ideas. What's my next step: taking out the keyboard to see if the cable loosened, even though I went nowhere near the cable??
    Thanks!!

    So it's been a while, but these things can drag out in life...now my brain is starting to adapt to the change, and that's annoying, so I'm back at trying to fix this.
    I tried safe mode, and the problem persists.  I tried returning all my startup options to default, and it persists.  I previously had returned to a Restore Point before the problem, and that didn't fix it. 
    Today I was going to look at the keyboard cable, but getting the top off is proving to be difficult and since I can use the machine as is, even if annoying, I don't want to go there yet.  Besides, there is no reason for this to be a hardware issue:
    I aborted a bootup by pressing and holding the power button.
    Next bootup failed, and the machine asked me to restore to a previous Restore Point.
    I turned off the machine again instead of restoring, and ever since then I've had the keyboard problem. 
    I tried uninstalling the keyboard and restarting computer so the driver reinstalls, and that didn't fix it.
    I plugged in an external keyboard and that worked fine.
    I am now wondering about using Linux to get at the problem.
    Any ideas?  I totally appreciate how active you are on this forum, and all the folks you've given advice to.  You are making computers work for people: thanks!!

  • When I shut the lid to my computer and then open it again the screen comes on and then goes black and I have to press random keys to make it show again.  Does anyone know why this is happening?

    When I close my lid to make the computer sleep and I open it back up again when I am ready to use it the screen turns on and then turns black.  I have to press random keys to make the screen show again.  Any help is greatly appreciated!

    First, before you sleep your MBP, make sure you either scroll down the Apple menu to sleep your machine, or do it even more easily by pressing CMD-OPTION - DiskDrive (upper right hand corner of your keyboard). I wouldn't just close your machine to let it sleep.
    It's hard to know exactly what's happening, but here are a few pointers.
    1. Go to System Preferences/Energy Saver and make sure you've set a sleep time of more than two or three minutes. Your machine may be trying to sleep too early. In the same preferences, set Computer Sleep to more than ten minutes, to make sure you don't get an unintentional sleep.
    2. Take a look for third-party applications you might have installed.

  • Keyboard Malfunctions 1 week outside warranty

    Greetings:
    (First off, I checked out the helpful troubleshooting hints page on Keyboard malfunctions when logging on here. No go.)
    Just one week after my eMac's 1-year warranty expired, my keyboard's suddenly lost registering the left-right-down arrow keys, the keypad's 0,1,2,3, Enter and period keys. No drops, no spills. The only remotely possible "cause" is plugging in my Gizmo flash drive into the USB port and getting that "bad power, shutting this USB port down" message, but I've had that before without problems. Still, could've that scrambled some internal keyboard drivers somehow? I dunno. Just fishing!
    If the keyboard's corrupted but good -- even after some last ditch surgery, can anyone recommend some (cheap!!) keyboard sources for a replacement?
    Thank you all!
    James Greenidge

    Greetings:
    A question to the true Mac techies (or engineers!) please!
    What could cause an eMac's original keyboard to just suddenly stop registering a whole bank of keys (left-right-down arrow keys, the keypad's 0,1,2,3, Enter and period keys) without any drops or liquid spills or crumbs ever being involved? Could plugging in an USB device into the keyboard's USB port "the wrong way" cause a minor short-cicuit that would zap the keyboard's control circuitry? Any theory would be conforting. In my world, nothing happens without SOME cause!
    Thanks a mint!

  • Non-responsive keys on keyboard.

    Hi guys,
    I hope someone can help me out figuring out my problem. I have MacBook Pro 13-inch, Late 2011, Processor  2,8 GHz Intel Core i7 Serial Number  C02HG0WKDV14 Software  OS X 10.9.5 (13F34).
    One day I turned my mac on and it had "M" key stuck, it just kept typing this key. I tried resetting SMC, PRAM and all advices on-line with no success so decided to open it and clean it all up.
    During the clean up I accidentally pealed off the black foil on the backlit which I thought caused the following issue of various random keys being non-responsive. So I bought new backlit which in the end did not fix it at all.
    Bellow are highlighted the non-responsive keys
    One thing I noticed that all keys started to work when was on the plane, probably the pressurized cabin made it work.
    Do you by any chance have any ideas what is the problem? How can it be fixed? I just can't live airborne
    Thank you for your help

    The best thing to do would be take it to an Apple store genius bar and have the techs check it out and see what is wrong with the key switches.
    By the way, the "pressurized cabin" of a commercial airliner is actually at reduced atmospheric pressure, only about 80% of the pressure at sea level.  That should not have a physical affect, but have the techs check out the keyboard.

  • My computer is possessed: random key presses

    I have a weird problem, with a lot of history.
    The basics are: for several weeks now, my computer has been possessed with random key presses. Often when I am typing, a random letter will pop up, or my mouse will click at random times. For example, when I am playing an online game, a grenade will randomly get thrown, or my right mouse button will trigger, even though I didn't press it. But it is not limited to the game, it is in all applications.
    My basic question: is there a program that can record or show not only key presses, but where the press came from? I don't know if it is a hardware or software problem.
    Hardware I have: Apple Keyboard, Belkin n52, and a Logietch MX Revolution (just received yesterday, so the problem is older then the mouse).
    For software, I am running ControllerMate, so it might be the culprit (I have a few simple layouts, so it is not some random node that is running).
    To top it all off: about a month ago, I was banging (fake typing) on my keyboard, and my "a" key quit working... for two days. Then it started again. Maybe these random key presses are from a bad keyboard... but would it be able to generate mouse clicks?
    ADDED: Yesterday I ran Disk Utility from my install disk and both repaired permissions and repaired disk (there were some problems with the disk), but the problem still exists.
    I am so confused...

    For example:
    I have a button on my n52 that changes settings for me, and when this button is pushed, one of the LEDs lights up, and I get a Growl notification.
    In the last 20 minutes, this button has been "pushed" three times, even though I have not touched my n52.
    I have no idea why this is happening, and it is starting to annoy me.

  • W500 keyboard malfunction after switching displays

    Anytime I use the FN + F7 key combination to switch the monitor displays, the keyboard malfunctions. None of the keys behave correctly; they behave as if I'm holding down the windows key as well, even though it was never touched. 
    To fix the problem all I have to do is press the windows key once, and the keyboard will behave as normal. However, we have several of these laptops that we loan out to customers, so we were hoping that someone has a better solution than to put a note on each laptop explaining the bug. 
    Thanks for the help,
    Matthew

    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. When done, 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

  • Simulate that i hold an random Key.

    Hey,
    i just oponend an discussion for an long time ago and marked those as solved, but ihe advice from User called Melophage doesn't helps.
    "Hey Guys,
    i just want to generate an Caps Lock Function for my Option Key, cause of my handicap i couldn't hold this Key anytime.
    Any Suggestions or advices to fix my problem as soon as possible.
    Thanks in advance.
    n1mare.!
    n1mare,
    KeyRemap4MacBook will allow you to set either Option key (or both Option keys) to act as a Caps Lock."
    Hi Melophage,
    i just need to correct my reply. It doesn't works. I don't want to act with my option keys as Caps lock. I just want to simulate, that i hold those Keys. (for example Shift_L & Option_R)
    Hopefully my explanations are understandable and you could help soon as possible.
    Many Thanks.
    n1mare.

    n1mare,
    if you still have KeyRemap4MacBook installed, you can set up a “Control Lock” function through e.g. checking the “▼ Change Control_L Key (Left Control) → Control_L to Sticky Control_L” checkbox — this would turn the left Control key into a Control Lock key.
    Alternatively, you could open the Accessibility pane of System Preferences, select Keyboard on the left-hand side, and then check the “Enable Sticky Keys” checkbox to have all of your modifier keys act as Lock versions. If you choose this option, then I’d recommend also checking the “Show Accessibility status in menu bar” checkbox.
    I don’t know of any program that will set a random key to be a Lock key — the choices in KeyRemap4MacBook are all for specific keys, not for making one random selection out of all of the keys.

  • Macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again

    macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again lik it did before

    If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
    It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
    Good luck - take the issue as high up the food chain as you can and see what happens.

  • By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

    By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

    rajlego,
    in the Keyboard pane of System Preferences, select the Shortcuts tab, and then select Mission Control on the left-hand side. On the right-hand side, make sure that the Mission Control checkbox is checked, double-click on its current key combination (by default “^↑”) so that the key combination is highlighted, and then press the F3 button — that will set its shortcut to be F3. You can now press F3 to bring up Mission Control without needing to also press the Fn button.

  • TS1381 My left arrow does not work on my macbook pro(model A1226).  I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, test all other keys with keyboard view (all others work)  - HELP!!

    My left arrow does not work on my macbook pro(model A1226).
    I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, & tested all other keys with "keyboard viewer" (all other keys work except for the arrow). 
    In addition, I have gone thru all the recommended checks with universal access and have booted from snow leopard dvd and the left arrow still does not work. 
    I have tried using the left arrow key in all of applications I use such as: excel, ms word, address book, calendar, iphoto, terminal, & highlighting an icon and using the arrows to move to another selected icon.
    Here is the kicker!  In addition, I purchased a logitech solar bluetooth keyboard and the arrows work fine with my ipad but do not work when paired with the macbook pro. All other keys work fine on the macbook pro using the bluetooth keyboard.
    I believe this says that the problem is not in my macbook pro keyboard. So where can it be?
    Can anyone think of any other rabbit holes I can search?
    thanks and regards

    I would also like to add that I've reverted the two cd drive and hard drive mods I did and the laptop is back to factory hardware and there is 0 corrosion or mold visible.

  • Sound keys on keyboard no longer control sound. What should I do to fix this?

    Sound keys on keyboard no longer control sound. What should I do to fix this?

    Hey Bill,
    Check to see if the option for "Use all F1, F2, etc. keys as standard function keys." is turned off. When it is turned on, you would need to hold the Fn key while hitting one of those keys will make it work they way icons are displayed. To find out where this option is, go to System Preferences > Keyboard and in the Keyboard tab is where you want to be. Take a look at the article below for more information.
