My keyboard backlight won't work

I tried to dim my keyboard backlight and the dialog came up but there is a circle with a slash through it like it is unavailable, not allowing me to dim or brighten my keyboard. Then the lights dimmed and I cannot bring them back up?  Whats up with this?

If you are in a well lit area this will pop up on the screen.

  • Keyboard backlight won't turn on after spill.

    Yeah so, me being a complete idiot, I was holding an open bottle of Snapple right next to me while laying down on my bed browsing stuff when I inevitably spill it everywhere. All over my sheets, clothes, and of course my keyboard. I immediately turned it upside down and drained the liquid, also rubbed the entire keyboard with a wet rag and some rubbing alcohol. All the liquid/stickiness is gone and the keys work perfectly fine, albeit the smell is still faintly there. But the real problem is now my backlight won't work. I noticed it flicker while cleaning it but thought it was nothing.
    Any general way on how to fix this? And no, I'm not spending a thousand bucks and wait a month for some dudes to take the whole thing apart and wipe out my harddrive again for no reason.

    OK, Wow.
    Whenever a liquid spill occurs the first thing that has to happen is the laptop should be shut down immediately. All power must be removed as soon as possible. It is especially important that the battery be disconnected and removed.
    All affected parts must be removed from the laptop. No attempt should be made to start/restart the computer since this could potentially damage the logic board beyond all repair.
    Then all affected parts would be washed in deionized water and blown dry with compressed air. (In a water spill the deionized water is probably not as critical. Depends on the mineral content of the water.).
    This is especially true of the large chips on the logic board. Liquid can wick under them and cause havoc for weeks if not months after the incident.
    The logic board should be placed in a drying/dehumidifing oven for at least two days. Longer depending on the spill.
      The keyboard is a separate matter as described below.
    This is how these keyboards work:
    This is the contactor array of a MacBook Pro 2011 13" . You're looking at it from back to front. Those round dots are where the silicone rubber "cones" cause the front array to make contact with the back array, telling the computer which key has been pushed. The width of these (I think deposited silver ) traces is about 0.5 mm.
    Now you're only looking at the just the front array. You can see that the contact pads are connected in series. A break anywhere in the trace connecting them would cause the "downstream" keys to stop working.
    So here you see a site where ionic corrosion occurred. I know that this particular MBP was exposed to water. So I bought it very cheaply. I was able to clean and completely dry out the logic board and the MBP worked fine for a while but quickly the Q - W - E - R -T - Y - P keys got wonky then completely stopped working. I bought a replacement keyboard for cheap but then found out that it's held to the front frame with around 80 tiny screws. So I was using it with a BlueTooth keyboard. Recently I bit the bullet and for $69 bought an entire top case for my machine. Putting it in meant that the everything had to come out of and off the top case.
    So you can see from the amount of corrosion, it doesn't take much to cause a failure. In this case a drop of liquid less than 0.5 mm would, over time with ionic action, cause a failure. There was a post about someone who had their MBP in a leather case and when they opened it up there was a lot of moisture on it. It was winter where he lived and we figured it was condensation. So even without spills this could happen.
    So since your problem was with a sugary drink the sugar will be hydroscopic, that is it will attract water out of the air and keep the contact area moist. This will lead to future failures be it on the logic board on on the keyboard membranes.
    The backlight being part of that array you've been looking at. (Finally got to it.)

    Sounds like it could be a hardware problem.
    Try a restart or reset to see if that helps. If not, contact Apple Support.
    Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.
    Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).

    I recently updated my MacBook Pro to OSX 10.8.4, but now my keyboard backlight does not work and there is nothing I can find in the Keyboard section of preferences to turn it back on. Anyone else had this problem?

    One of these steps should help.
    1. Restart.
    2. Press F6 key couple of times.
    3. System Preferences > Keyboard > Keyboard
                           Uncheck the box next to "Adjust keyboard brightness in low light"

  • My keyboard backlights is't work well

    a few weeks age i turn on my mac and the keyboards backlight are not working till last night when i watching a video the lights came up , and tommorow it's gone again , what do i do ??!!! :S

    If you are still under warranty and/or have AppleCare, call them.  Let them deal w/it.
    Out of warranty, take your MBP to your local AS or an AASP.  Diagnostic testing is FREE!
    Something else to try:  Update your OS to last version of Lion.  Use Software Update or the Lion combo update to update your OS.  Also, update everything SU has to offer for your computer.  When done, repair permissions and restart your computer.

  • Keyboard lights won't work

    so i have a mid-2009 macbook pro: 13-inch, 2.26Ghz.
    it was running 2GBs of RAM until this afternoon when i upgraded it myself to 3GBs with a 2GB stick.
    i followed the instructions from apple to the absolute letter. however now, my keyboard lights aren't working. but it's funny... usually in direct light, the Fn keys that control the keyboard lights won't allow you to adjust the light, right? but they will for me, except there's no light to adjust.
    i couldn't have done something, right?! i mean... i was was super careful and only handled the ram section, after which i blew off some dust and sealed it up again.
    please help!

    sadly... no success
    i followed the instructions exactly; restarting and all. no luck. i did hold the buttons though... is it supposed to be a hold, or a quick "hit"?
    i saw your post about a better look, so i opened the back again and took a better picture.
    http://i1220.photobucket.com/albums/dd457/jakemoney/IMG4175.jpg?t=1284811603
    you can see the connector just below. i tried, again, to make it go in. it fits, but i can't get it to stay. that must be the job of a professional. i can't do anymore now - i'm too involved, and i'm worried i may break more than just some stupid backlighting on my keyboard.
    in other news: iphoto does open a lot faster now!
    thanks again.

  • MacBook Pro Mid 2010 13", Lion 10.7.2, keyboard backlight / ALS not working

    Since upgrading to Mac OS X Lion I have had problems with keyboard backlight and the ambient light sensor. I realized that the problem seems to be caused by ambient light sensor or hardware detection issues. LCD is not auto-dimming with light intensity variation. Since then I've done a Snow Leopard clean install and upgraded to Lion with no success. Then I have done clean installs of Lion using USB Keys with versions 10.7.0, 10.7.1 and 10.7.2 and the problem persists. Under Snow Leopard everything works like a charm.
    SMC and PRAM reset did not solve the problem.
    When I press F5 and F6 to adjust the backlight nothing comes up on the screen.
    No settings under Keyboard menu.
    Any ideas on how to solve this?

    Max,
    I have the same model MacBook Pro as you. Have you tried erasing your internal disk, reïnstalling Snow Leopard from your grey Mac OS X Install DVD, and running Software Update to get it  to 10.6.8, to see if it also misbehaves under Snow Leopard?

  • Zoom keyboard shortcut won't work with "Italian Pro" keyboard, Zoom keyboard shortcut won't work with "Italian Pro" keyboard

    Hi everyone,
    I am trying to get to the bottom of this mystery. "Italian Pro" is the keyboard I use almost all the time, and for some reason this zoom shortcut won't work. Another user assured me that "cmd-+" is the shortcut also in that keyboard. Mine doesn't work though. I have tried removing the keyboard and reapplying it. I've tried to use it on different browsers and different applications. I've even created another user and logged into that, installing the keyboard there. Nothing has worked, so can anyone suggest anything? What do I do next? (I know it doesn't seem like much but the issue really interferes with the flow of my things) Thank you!

    If we're talking about (b) and (1), then this 'other user' (his initials wouldn't be TG, would it?) was right. My keyboard is US QWERTY, and, if I switch to Italian Pro, ⌘-+ works. However, as the 'other user' has already told you, to do ⌘-+ with the Italian Pro keylayout on the US QWERTY keyboard, you have to press simultaneously the keys labelled ⌘ and ] -- as you can easily see in Keyboard Viewer.

  • My keyboard chortcut won't work

    I try to create a shortcut for a software that I frequently use, it won't work. I assigned "cmd + t " to it under keyboard shortcut of the keyboard and mouse. Even my roommate has this problem too. Is there anything I need to setup before customizing key short? It is very frustrating since this feature is one of the reason why I got my mac yesterday...

    Welcome To  Discussions KelWong!
    You could also just put the application in the Dock, for easy access to it.
    Navigate to the folder where the application is. Probably the Applications folder.
    Locate the application, and position the cursor on it.
    Press the mouse down, and drag the application to the left side of the Seperator bar on the Dock.
    When the icon appears in the Dock, release the pressure on the mouse.
    When you want to load the application, just click on that shortcut.

  • Undo keyboard shortcut won't work

    I have quite a bizaare problem - the keyboard shortcut for undo will work after I restart my computer, but after awhile, it simply stops working.  I am thus forced to click on Edit->Undo every time I want to undo something.  Once the shortcut stops working, it applies to all applications.  I have not been able to identify any "trigger" which causes it to stop working.  I've tried to "Restore defaults" in the Keyboard shortcuts tab under the Keyboards menu, but this didn't have any effect.  Any ideas?

  • F7 and F8 Keyboard shortcuts won't work correctly.

    I've just recently installed LR3.6 and it's my first experience with LR.  I've been following Lynda.com tutorials and all of a sudden the F7 and F8 function keys won't work.
    The F7 just does nothing and the F8 opens iTunes every time I press it.  I've tried everthing I know (not being much of a Techie) without success.  I installed one upgrade download since I installed the original CD software. Should I just delete the program and re-install the program?  I believe the F-keys were woking originally.  I'm sorry, but I was going thru the tutorials and not being as observant as I should.  All I know for certain is that they do not work now.
    I'm using an iMac 27 with the wireless keyboard. OSX 10.6.8.
    Thanks for any help. - John, Vancouver, WA
