What did you open if if was already opened?
As for your non-working keys, perhaps debris somehow got beneath the keys.  Especially if you were eating while using your computer.  Spilled anything on the keys lately or previously?

If none of the above applies to you, you could have a hardware issue.  If you have Apple Care, call them and get a case number.  Otherwise, take the computer to an Apple store or an AASP.  Whichever is more convenient for you.
Liquid damage is not covered under Apple's standard 1 year warranty or Apple Care.
NOTE:  If you are out of warranty and purchased the computer with a credit card, discuss the warranty issue with the credit card company which you purchased the computer with.   They are the only ones who can at this point cover the computer after it goes out of warranty with the manufacturer (Apple).  
If you have Homeowners insurance, place a claim with them.

  • Ultraslim wireless keyboard and mouse not working

    Hi ,  I purchased the Lenovo Ultraslim Wireless Keyboard & Mouse (pn: 57Y4700) about 4 months ago for use with my T60 laptop (which i use with a docking station and large lenovo monitor at work).
    Everything was woking fine until last Monday when I can into work after the weekend and neither the mouse or keyboard worked. I replaced the batteries in both, rebooted the machine several time, switch the USB ports for the nano receiver, but nothing seems to have worked.
    I looked online for troubleshooting options, but did not find anything.
    The mouse and keyboard don't seem to have a "sych" button - if I recall correctly everything worked right out of the box.
    My theory is that the nano reciever was damaged (not sure how) -- but don't know how to proceed:
    can the nano reciever be replaced;
    any other options to troubleshoot;
    any chance that this could be a software problem
    Thanks

    Hi coffee12345,
    Welcome to the HP Forums!
    I have read your post on your wireless keyboard and mouse not working with your desktop, and I would be happy to help you! To begin, I need to ask you a few introductory questions:
    What is the Product and Model Number of your desktop?
    What version of Windows are you using?
    Is this a recent issue, or has it been like this since day one?
    Are you using a USB hub to connect your peripherals or is it directly plugged into the computer?
    Please re-post with the necessary information, and I look forward to your reply!

  • Keyboard keys are not working

    Im on mac OS X 10.6.8 several keyboard keys are not working. For instance the at symbol is not working or question mark and random other punctuation keys. The problem started after running some code from terminal to trun off mouse acceleration and then installing a plug-in to control more accurately the mouse funtions. Ive since uninstalled the plug in and disabled the adjustment in terminal. Ive checked all the normal keyboard funcions to make sure settings were not funky. When I log out and log in as a differnt user the problem with the keyboard is fixed. Someone please help
    Code I ran
    defaults write .GlobalPreferences com.apple.mouse.scaling -1

    Hello lindzthecreator,
    I suggest this part of the article named One or more keys on the keyboard do not respond found here http://support.apple.com/kb/ts1381
    Some keys don't work as expected
    From the Apple menu, choose System Preferences.
    From the View menu, choose Speech.
    Click the Text to Speech tab.
    If "Speak selected text when the key is pressed" is enabled, the key or key combination set to speak text cannot be used for other purposes or used to type text--click Set Key and change it to a less-commonly used key combination (try to use modifier keys such as Shift, Command, Option, and Control). Or, disable the "Speak selected text when the key is pressed" option.
    Click the Universal Access pane in System Preferences, click the Keyboard tab.
    Make sure that Slow Keys is turned off. With Slow Keys on, you need to press a key for a longer period of time for it to be recognized.
    In the Universal Access pane, click the Mouse tab, and make sure Mouse Keys is turned off. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer (cursor). (There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.) If Mouse Keys is enabled and you are using a keyboard with no numeric keypad or Num Lock function, see Unable to type while Mouse Keys is enabled in Mac OS X.
    If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
    If the issue persists, use Keyboard Viewer to help isolate the issue:
    Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
    Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
    Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
    From the Input (flag) menu, choose Show Keyboard Viewer.
    If the keyboard is connected and detected by Mac OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit (or any text application), and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer.
    Start from the Mac OS X Install Disc, choose Terminal from the Utilities menu and test the keys which were previously not working.  If the keys work while started from the Install disc, then the keyboard itself is working correctly.  Use Mac OS X: How to troubleshoot a software issue to isolate the software issue that may be causing the keys to not respond.
    All the very best,
    Sterling

  • My "go to in point" and "go to out point" keyboard shortcuts are not working, and the default keys arnt either? any help would be amazing!

    my "go to in point" and "go to out point" keyboard shortcuts are not working, and the default keys aren't either? any help would be amazing!  I use these keys a million times a hour and since I have switched to cc I cant get them to work. track selection makes no difference or if there are markers on the timeline or not. 
    Anyone else feel me on this?
    any help?

    Well that still didn't make any kind of difference.  I would just do without it but I've becomes really use to it with Avid for so long.  I have to admit there are a lot of small moments like this that makes me miss Avid.  Any other suggestions? I have checked the keyboard shortcuts a few times and maybe I'm just missing something here...

  • Wireless Keyboard FN Key Not Working

    I have checked this box:
    I also tried the Firmware 1.1 update but I got a messege saying:
    "No Apple Aluminum Keyboards Found" and I paraphrase "Please connect the device or make sure it is turned on etc."
    I also tried the Firmware 2.0 update but got the same message. I can't physically connect the Wireless Keyboard to the Mac Mini I have. It's wireless FFS.
    I ALSO Installed the Bluetooth Firmware Update 2.0.1 and that didn't help
    Also I tried some advice from a forum mentioning a SMC or System Management Controller via these instructions:
    http://support.apple.com/kb/ht3964
    But nothing is allowing me to use my FN keys anymore. This is annoying because I thoroughly enjoyed volume control from my keyboard. Now it's gone.
    This all started when my old keyboard broke and I got a new one. I want my volume control back! Help me please before I jump out the window!

    Hi.
    My FN key is not working either. I have a macbook white (10.5.8) and a brand new apple wifi keyboard.
    F9 to F12 keys are working. F1 to F4 keys are not working.
    I've gone thought many posts (some are listed bellow). In short, I did the following already:
    - keyboard software update
    - keyboard firmware update
    - magic mouse software update (because some posts suggested that more than one Bluetooth device, like magic mouse, could interfere on Bluetooth keyboard operation.
    - SMC reset (above in this post).
    Most posts were saying  "uncheck the "use F1, F2......", then recheck it. This didn't work for me.
    I'd appreciate any help.
    Thanks in advance.
    Gus.

  • Wireless Keyboard Brightness Keys Not Working

    Hello.
    Since an update a while back the brightness adjustment keys for screen brightness on my apple keyboard have stopped working. These are the F1 and F2 keys normally.
    On my Macbook Pro keyboard they work fine but the wireless keyboard keys do not.
    Anyone having the same issue or know a fix?

    I had the same problem, minor but annoying. I found the cause, It is a combination of factors. If the following are true:
    • You're using a laptop
    • You are running 10.6.x (not sure which revision, true of 10.6.6)
    • You have an external display connected
    • The external display is non-Apple, or you don't have a USB connection to an Apple display
    • You are using an Apple Wireless bluetooth keyboard
    • You have the menu bar *on the external display*
    Then the brightness keys won't adjust the brightness of the laptop's display.
    The apparent logic is that if your main (menu bar) display is external, and you're using an external keyboard, then you must want the brightness keys to control the external display. The bug in the logic is that it doesn't check to see if the external display is capable of brightness control. So, it appears that the brightness keys don't work at all. Note that Max OS X can only adjust the brightness of an internal display or an external Apple display with a USB connection.

  • Hello, how much did you pay when some parts of the keyboard keys are not working properly due to accidental spilt of tea?

    I accidentally spilt a tea on the keyboard of my Macbook Air 11'. I managed to wipe the keyboard and saved my laptop. However, I noticed that the Spacebar, Shift and Command keys are not working as it should be. It's like something's stuck inside that makes these keys hard to press as usual. I refered this problem to Amsys, Berwick St London, as the reservations in Apple Stores are full. Do you have any idea how much is the cost for diagnosis and repair if ever?
    Please help.

    if you spilled a good bit of tea, its a serious problem, yes.
    it got inside, and will corode, and bad things will begin to happen.
    Liquid spills, why your MacBook chassis is a one-way valve for spills
    After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
    The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
    Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
    After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
    There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
    Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
    In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
    In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
    contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

    Intel-based Macs: Resetting the System Management Controller (SMC)
    Summary
    In some situations, you may need to reset your computer's SMC.  Learn how to identify these conditions and reset the SMC.
    Products Affected
    Desktop Computers, Portable Computers
    Note: It is possible that the SMC could encounter an issue that may cause unusual system behavior typically related to the symptoms described below. In some cases, resetting the SMC may be the only correct method to resolve the issue, however, an SMC reset should only be attempted after all other standard troubleshooting has been performed.
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC.  Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.

    Unplug the MagSafe power adapter from the Mac and the wall power socket for several seconds.
    Shutdown the Mac. Physically remove and re-insert the battery (if it's removable) and startup the Mac.
    If the issue is still not resolved after following the troubleshooting items above, an SMC reset may be necessary.After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:Fans
    The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.Lights

  • Dv6 2190us - some keyboard keys are not working

    Hi there all,
    My sis bought me Dv6 2190us laptop last Feb 2010 and I just got it now. The problem now is, some of the keys like the letters - W, S, and X are not working so I am not able to log-in to Window 7. The laptop is brandnew, the keys are not sticking but the only unusual thing is that , the battery was attached to the laptop for one year.... Couldnt this be the reason and what should I do to resolve this? Appreciate your kind help!
    Thanks in advance,..

    also having this issue with 6 month old dv6 3031 but my entire line beginning with a to enter key will not respond so i cannot do any tests or what not. i was advised to do bios setup by clicking F10 when notebook is booting up, arrow across to Diagnostic menu and perform PRIMARY HARD DISK SELF TEST. of course i was unable to do this as my enter key does not work but maybe you could give it a go and have more luck
    cheers

  • Few keyboard keys are not working

    I am Using Mac 10.5.8
    Yesterday, when i made my laptop shut down, all the keys were working perefectly.
    Even when i started it today, for few minutes ie 5 minutes all the keys were working fine, But then i don't what happned suddenly.
    Pointer starts blinking.. Down arrow key was getting pressed itself.
    Later i restarted it, and found Right click on trackpad was not working, and all arrow keys along with right Command key are not working.
    Then i restarted it again, command keys started working, and up ,left & right arrow keys started working.
    I verified my disk, then i found right click started working.
    The only key was not working down arrow key.
    But after 30 minutes Right key stopped working and Right command key too
    Suggest me what should i do now, it seems more like some software problem in comparison to Keyboard hardware problem.

    Hey i guess that's not a good idea, Could you please let me know something about some hardware check/keyboard viewer.
    Anything like that ?

  • Keyboard keys are not working at startup

    when i start my laptop the keys of keyboard are not working except the movement key and numeric enter key.
    but when i turn of the narrator keys are starts working excepts some (such as: right control, function keys in some way,i.e.
    wi-fi, volume,brightness & other are not working ) everytime.even it wake up from stand by mode.
    function keys are work in genrel way i.e. F1 to F12.what can I do to resolve this.

    hi ,
    follow this steps please ,
    1. Right click on My Computer Icon > Properties > Device manager (on the left side)
    2. find the Keyboard > Right click on it > CHeck for updates
    3. Make sure that you installed the right Driver for Your Keyboard proided from HP official website
    if these didn't help
    try using another OS (replace your Win version)
    ** for experts only : you can use UBUNTU live disk to check the Keyboard without uninstalling you win version
    if changing the OS didn't help
    now it's one of two things
    1. there is a problem with your BIOS
    2. there is a HW problem
    and in both cases i don't recommend you to start solving it yourself
    Updating the BIOS is very sesitive operation and also the HW problems
    so please look for the nearest HP support center to your city
    and make sure that they will solve your Problem
    Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
    Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

  • Portg R500 - Blue Screen and keyboard mouse are not working

    Hi All,
    I am using windows XP, well I was not any more due to below problem.
    Laptop blue screened and now any time it goes to windows xp screen blue screen comes and reboot the system. Its not working in safe mode at all. Keyboard any mouse are not working. I cannot even go to BIOS.
    I tried to plug a USB keyboard but still its same. I cannot even boot from CD.
    Please could some one advise what do I need to do in order to resolve the problem.
    Thanks in advance.
    Nysoh

    Hey,
    How you can test it in safe mode if keyboard doesnt work? I mean before Windows starts you have to press F8 key and then go down to select safe mode. Therefore you need the keyboard
    In your case I would try to remove the battery and AC/DC adapter for at least one hour. Then connect both devices again and make sure battery is fully charged. Start your notebook and try accessing the BIOS setup and load the default settings.
    If Windows doesnt start you have to do a recovery installation I think. Some Windows files might be muddled up
