Backlit keys no longer working...

After recent SMC? firmware auto update, my backlit keys no longer work.
When I try to turn them on (dim/bright) via keyboard shortcut keys, I get a circle with a slash thru it on the on-screen keyboard logo...

Hah, Im not sure but I may have the opposite to your problem. I'm here in a very dark room, so the back light comes one, but *I am watching videos* so I'm not touching the laptop. The keys would go dark until I touched the laptop again or that is what I thought. Now the back light comes on randomly. I'm going to have to research this keyboard to see what sets it off.
It occurs to me that you're getting a light show based on overall brightness fluctuations in the program content of your DVD! Do the keys light up when a dark scene is on the screen? Then go off once the light level in the flick goes back up?
Take your Apple-branded black cleaning cloth and drape it over the iSight camera, which is where the ambient light sensor is. Sort of like playing peek-a-boo with the MB! (We have a 2 1/2-year-old daughter [not MacBook]). Great way to test the KB backlight (which we didn't get ourselves, BTW).

  • Apple store replaced logic board backlit keys no longer work

    So about a week ago I had to have the logic board replaced because airport would connect only half the time. The apple store did fix the problem, but only one more thing, the backlit keyboard no longer is recongnized, its like the employees didnt plug it back up, my main question is is that I have to have the laptop for school, how long would it take the apple store to fix or if its simple could I fix myself.

    I would make another genius bar appointment, they could do it while you wait in the store. I understand this is the preferred policy now at the genius bar to prevent them from taking in all sorts of machines. If they are busy they will have to make the repair after hours when the store closes. They will usually quote something like 1-3 business days but in my experience it has usually been 1-2 days.

  • Function keys no longer working with a new keyboard...

    I got a new keyboard and my function keys no longer work with it.  I am used to have them used in the standard format, i.e. F10-F12 control the voume, etc.  I have the "Use all f1,f2, etc." button clicked.  I have also tried restarting my computer.  Any thoughts?

    Try doing a SMC reset and PRAM reset.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • All of a sudden my Enter key no longer works in SQL Developer.

    All of a sudden my Enter key no longer works in SQL Developer. I don't know how I managed to disabled it. Can anyone tell me how to re-enable it?
    I already tried the following:
    - I closed the application and re-opened it. - It didn't work
    - I re-started my machine. I didn't work
    Help! Thank you

    The same thing has just happened to me and this was very useful to correct the problem --- but now I am wondering why or how this happened. To the best of my knowledge, I haven't make any setting changes so why did I lose the Enter action?

  • Control key no longer works after update.

    After updating Lion the control key no longer works. It beeps when pressing control and then a number key but nothing happens.
    This is left control key though. Right still works?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
    Below are four lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
    Some of the commands will line-wrap in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
    To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search.
    Step 1
    Copy or drag -- do not type -- the line below into the Terminal window, then press return:
    kextstat -kl | awk ' !/apple/ { print $6 $7 } '
    Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
    Step 2
    Repeat with this line:
    sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
    This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
    Step 3
    launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
    Step 4
    ls -1A {,/}Library/{Ad,Compon,Ex,Fram,In,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* 2> /dev/null
    Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, change it to something like “[email protected]” before posting.
    Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
    You can then quit Terminal.

  • Return Key no longer works in sql windows or procedure editors.

    The <return> key no longer works in my SqlDeveloper editors. Is there an easy fix? I tried resetting the Option for the carriage return but it did not change anything.

    So if you go to your shortcut keys (Tools > Preferences > Shortcut Keys) and search for "Enter", what commands are associated with the Enter shortcut? If you have tried remapping the Enter key to something else, it may have removed the standard association with the "Insert New Line" command.
    You can reset to the default (which should fix the problem, but lose any custom shortcuts) with More Actions (top right) > Load Keyboard Scheme > Default.

  • Backlit keyboard no longer working.

    I just recently upgraded my 2010 macbook pro RAM. I went from 4gb to 6gb and now my backlit keyboard is no longer working. I have tried messing with the keyboard settings as well as the F5 and F6 buttons. The keyboard does not even come on in low lit conditions. Why is my backlit keyboard no longer working?

    Hi...
    Try Resetting your Mac's PRAM and NVRAM
    If that doesn't help, try Resetting the System Management Controller (SMC)

  • I and K keys no longer working on Macbook keyboard

    The I and K keys no longer work, it seems. I've restarted, attempted to clean out the keyboard, restarted again, etc. No dice. Sometimes when I push I or K I'll get an odd string of characters--'YIOU' or a bunch of symbols--but mostly I just get no response. I wasn't doing anything unusual when this started and I didn't spill anything on it.

    Welcome to Apple Discussions!
    I have heard around the message boards about this kind of problem, and no one seems to know what the problem is. Your best bet is to take it into Apple and they can fix it for you. If you are in warranty, they shouldn't charge you, especially since you didn't spill anything into the keyboard (also a common problem). if you are out of warranty, you're looking at around $90 or so (still better than not being able to finish that email or that final report!). i had my keyboard replaced for a different reason, but the receipt said I would have been charged said amount had I not been under warranty.
    hope that helps!

    Cheers! Store is now working. I didn't quite do things in your order as your post came in after I started experimenting. This is what I did:
    Three-finger reset again.
    Installed the .sisx file above (cwrt core).
    Installed the Nokia Store from Betalabs (with Qt 4.7.4).
    Read your post, so deleted those two files you mentioned from installated apps.
    Installed earlier version of Nokia Store from your link.
    Ran this, which prompted me to upgrade.
    Can now log in without the black screen.
    It seems remarkable that doing a factory reset means the phone doesn't work.
    That's the question;Nokia advise to never do a 3 finger hard reset.this process delete some files that isn't recoverable even reinstall software.
    I have a C7 as well and already perform a 3 finger hard reset,but a software reinstall put it back as 2out of the box".don't know why this do not works in Nokia 701 
    At least you have the store back again right?
    As far as i know it should be missing in your phone,the photo and video editor right?
    That's why i took mine to Nokia Care Center,they put the phone as out of  the box.

  • Up volume key no longer working after 10.3.1

    Since OS update on Passport to 10.3.1.1581 the up volume key no longer works in an app. I first noticed it while watchin a YouTube video in browser, then in Neutron music player then the Music app. The button works fine to advance songs (long press). At first I rebooted and it seemed to work, then it stopped. 
    Then I noticed that it works on the home screen just not in any apps.  It's a pain to have to exit the music app, go to the home screen to increase volume. 
    Down volume and pause/assistant works fine. Up button works fine in Camera to take shot. 
    Have rebooted many times since upgrading. 
    Any suggestions would be appreciated.

    Try reloading the 10.3.1 update again just in case something in the update went wrong.
    Also, are you updating through BlackBerry link or over wifi or cellular? I always reccomend updating through BlackBerry link just to prevent a corrupt update in case the signal drops. BlackBerry link will greatly reduce the chance of a corrupt update as long as the USB cable is not disconnected.
    Good luck and keep me posted.

  • Ever since I updated my Macbook Pro, the shortcuts on the F1-F12 keys no longer work as they did before.

    Ever since I updated my Macbook Pro, the shortcuts on the F1-F12 keys no longer work. I used to press just the F12 key and I would be able to raise the volume, now it switches to the home page. I want the old shortcuts back and I don't know how to do that. Please help.

    Ever since I updated my Macbook Pro
    updated from what to what?
    Suggest you try a NVRAM / PRAM reset, as described by Apple:
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Enter key no longer works for calculator or emails

  • Enter key no longer works in address bar

    Hi, In the last couple of days, the enter key no longer works in the address bar, which is really annoying !
    If I type the address I want to go to, and then hit "enter", nothing happens. I have to manually click on the "go to" icon to the right of the bar.
    Is this a setting I can change back please, I certainly haven't done it knowingly or willingly, and it is really spoiling my web use on FF. I am on 3.6.13.
    Cheers !
