LED Backlight Keyboard not working

I downloaded OSX Mountain Lion in August of 2013 and immeidately after downloading it, my LED backlight keyboard option completely disappeared off of the Keyboard Preferences. There's a blank spot where the LED backlight keyboard settings should be. The F5 and F6 LED keyboard keys are also unresponsive. Is there anyway to fix this? Or do I need to take it in and get a new keyboard? I am currently operating OS X Mavericks 10.9.

    If this is a new laptop, I think I would either get ahold of MSI for warranty support or return it to the store you bought it from for repair or replacement.
    it is new but it has now no warranty because i have open the under hdd.
    And now i have a another problem. .!
    the battery was at 6% so I went charging.
    it says that the battery is charging but remains at 1%, and if I disconnect the adapter from the laptop, the laptop goes shutdown. 
    Without the adapter the laptop will not open.

  • MacBook Pro 13" Early 2011 Backlight Keyboard Not Working?! Software Problem...

    So my "MacBook Pro 13" Early 2011" backlight keyboard hasn't been working. I have tried LabTick today, doesn't fix anything. Even in high or low lighting situations (dispite the Adjust keyboard brightness in low light being off) doesn't like to go on. It doesn't give me a circle with a cross like it does with that box checked in day light. It shows on the screen the
    16 dots fully light after hitting F6 fully, just it doesn't light up. I one time had to reset my Mac OS at the Apple Store, it fixed the problem, but when I restored with a time machine backup, it went back to this software problem. How can I fix this?! What is wrong with my OS? Mountain Lion? How can I fix this?!

    If it does not detect the display automatically, try going to system preferences>displays, click detect displays.

  • 2006 Macbook Pro 17 inch duo 2 core backlight keyboard not working

    I have a Macbook Pro 17 inch model MA611 L/A 2.33 duo 2 core.  I recently had to change the hard drive and when I put everything back, the backlit keyboard is not coming on.  I have reseted the SMC, downloaded labtick, and can see F9 and F10 light up and down setting on the keyboard.
    It's not coming on.  I double check to make sure that the keyboard ribbon is on securely.  The keyboard is working as I am typing this post on it.
    Nothing seems to be a problem other than the backlit keyboard not coming on.  Is it possible that the LED light is broken even though everything on the keyboard works normally?
    Am I missing something?  Anyone have experience like this? 
    Any help or clues would be appreciated.  It is really bothering me and is annoying not having this feature at night.

    A Core Solo or Core Duo Mac can go to Mac OS X 10.6.8. A Core 2 Duo or better can go to Mac OS X 10.7.2.

  • Dv7-3165dx led backlight lcd not working.

    So the other day my laptop screen went out. i read about the dreaded black screen of death. Did a whole bunch of research and learned about the gpu needing reflowing, AND how to reset you computer and the blink codes and all that Jazz. i did the external monitor thing and lo-and behold everyting was fine. All it was, is that the monitor is not turning on. So I proceed to open it up and check all the connections. Everything is connected and all the plugs are clean. Did a full clean on the whole computer. I even reseated all the connections, made sure i have all the proper drivers and everything is up to date. NO conflicts anywhere.
         But still no monitor. Still I research again, some people say could be inverter board, but mine is led backlight. So there is no inverter board to change.  I reopen everything and check one more time. One cable looks a little off angle reseat it and try again. STILL no monitor. Shut it down and start it up the next day, BOOM it has lcd life!??!?!?!?!
         Start playing everything as normal and test it by putting it into sleep mode. It starts right back up. I turn it off all the WAY. Restart and she is dead again.
    This is where I am stuck. The Lcd right angle connector looks a little pinched but I don't know what is causing this. Can you help ME PLEASE!
    Again everthign works on external monitor. Sound works, Camera works, just no screen, EXCEPT once until full cold reboot. Then she is dead again.
    Is it the cable?
    Or is it the GPU?
    Or is it the LCD screen?
    OR something I may not have identified?
    Any help is appreciated.

    Hi @Sarteret 
    Welcome to the HP Support Forums!
    I understand that your built in display is not working consistently. It does sound as if there is some stress on the cable, and it is possible that it is an intermittent connection.
    Did you notice any difference with the display coming up or not when the built in display is moved? MOre specifically, if it is working and you move the display  a bit on its hinges does it stop working, or if it was not working does it seem like the screen may show some small signs of a connection?
    Also you can look at these, although what you are experiencing does sound more like a problem more with hardware, either the cable, or the connectors on either end of the cable, sound like possibilities.

  • Backlight keyboard stopped working after updating to snow leopard

    Hi I have a late 2008 macbook pro. When I got the laptop it had 10.5.8 on it and the keyboard backlight was working fine. I dimmed it all the way down to save battery life. Later on I installed 10.6.2 then did an update to 10.6.5. I don't know where it stopped working allong the way but the keyboard backlight no longer works.
    I can turn it up using the f keys. It will increase and decrease. There is not a circle with a line through it like I have read that other users have had when their backlight is not working properly.
    I can increase it and decrease it. The light never comes on. I have installed that program that lets you control the backlight by putting it in the taskbar, that doesnt fix it. I called apple and reset the SMC by taking the battery out and holding the power button down for 5 seconds then putting the battery back in and turning it back on. That did not fix it. I also asked if there was some preference files that we could throw away to maybe reset it. We tossed about 5 files and that didnt fix it - sorry I cant remember the files. I did a fresh install of snow leopard but i didnt go past the "would you like to bring back your files" part of the install.
    Can someone help me? The caps lock button lights up. I dont know if that matters. Please help me fix the backlight on my keyboard. I really dont want to install 10.5.8 again just to see if the light comes back on or not. Is there a bug in snow leopard that messes up my macbook? help!

    maybe its fried ? could be just bad luck when you were doing the update ?
    Ridiculous!
    To the OP:
    I'd recommend doing a SMC reset, if that doesn't take care of it do a PRAM reset. The instructions are:
    _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.

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

    My MacBook Pro keyboard not working correctly after Win7 bootcamp installation.
    Installation went well but when I boot either with OSx or Win it always keeps Windows keyboard.
    How can I have Mac keyboard in OS boot and Win keyboard in Win boot?

    Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
    I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
    Thanks in advance!

  • USB Keyboard not working after running Monolingual

    Okay, I'm not a Mac person and should have known that I was going to mess up my mother's iMac, but here it is -
    In an attempt to improve the mac's performance I performed all of the actions described in the following article: 11 Ways to Optimize your Mac's Performance     ( http://lowendmac.com/eubanks/07/0312.html ). Basically, I cleaned up files and 'other' system preferences. Things seemed to be fine and the computer did run much better. However, after running Monolingual and deleting what I understood to be 'unnecessary' PowerPC files the standard USB keyboard is no longer working.
    I've tried to search for various remedies, but have come to a dead end. So I'm left with reinstalling the Snow Leopard OS (I think it is 10.6.8?) BUT I can't because it is asking to input the account password (which I know) to make the change and I can't figure how to do that when the keyboard not working.
    Any help would be great!
    *feeling like a bone head*

    How are you trying to reinstall Snow Leopard? If you're booting from the Snow Leopard or iMac Install DVD that came with the system then that should eliminate any of the issues you may or may not have caused when you deleted did the clean up work on your mom's system.
    I suggest trying the following:
    0) Verify that the caps lock key is off. It can make inputting passwords difficult if you don't realize it is ON.
    1) Reset the PRAM by restarting the system then quickly press the command-option-P-R keys before the gray screen appears. Wait until you hear the computer restarts two times as indicated by the startup chime. For more info refer to http://support.apple.com/kb/ht1379.
    2) If the issue persists after the PRAM reset then boot from the Snow Leopard or iMac Install DVD, whichever you have. Once you see the menu asking you to choose a language try using the arrow keys on the keyboard to move the language choice selection. If the arrow keys are working at this point it indicates your keyboard is at least partially functional. Go ahead and select the language then proceed to step 3.
    3) Once the next screen appears move the cursor up to the menu bar area and pull down the Utilities menu. Select the 'Terminal' application. Once the Terminal application launches try typing the various keys on the keyboard and check to see if the correct characters are displayed. Please let us know if you detect any errors. If there are no errors then you should be able to quit the Terminal application and proceed with reintstalling the OS.

  • HT201401 Backlighting is not working how do I fix this?

    MY sister got a new phone and she gave me her iphone3. However the backlighting does not work, how can I fix this? Do I need to take the phone to apple?

    Try restarting the iPhone by holding down the on/off and the home buttons at the same time until you see the Apple logo.  If you are still having problems, then you should take your iPhone to Apple for repair. 

  • KEYBOARD NOT WORKING LEOPARD UPDATE POSSIBLE CODING ERROR??

    having read through all threads concerning this issue of internal MBP keyboards not working after installing leopard, and comparing to my own experience, it seems that everyone started having this problem soon after they must have downloaded the 1st software update to leopard.
    my MBP's keyboard currently does not work. How am I typing you ask?
    With the new apple USB aluminum keyboard. My boyfriend has it for his mac mini.
    Because all these keyboard problems are new and happening to everyone now, we have to assume this is related to the leopard update. They JUST released the aluminum keyboard around the same time they released leopard, so they probably had bugs with the usb aluminum keyboard and had to make some kind of change in the code with how leopard relates with keyboard input. so, it's most likely a coding error and we are at the mercy of apple for a freaking software update ASAP. Don't erase and install - because that will just take you back before the update, and then after you update your software again, it will happen again and your keyboard will crash. I updated my software yesterday and almost immediately started having this issue. my MBP is a week old and i had no issues before this with the keyboard until the update.
    The best thing we can do at this point is FLOOD APPLE WITH PHONE CALLS. We paid upwards of $3000 for a computer - holding down a key and messing with text edit is NOT acceptable.
    These are NOT solutions. Every time your keyboard stops working, and holds you up from doing your work, CALL THEM.
    That's what we think is happening...maybe something more severe is happening and we're wrong. but, hopefully, this is all it is and they will FIX IT as soon as possible because it's really annoying.

    Is anyone else running vmware or parallels?
    I had both installed at different times and realized that for whatever reason the kernel extensions for both were installed on my machine. I downloaded both from their respective website and ran the full uninstall.
    As of this moment my (then-persistent) keyboard issues are gone. I am not positive this was the solution as I just might not have had the problem yet (as they tended to be very sporadic), but it might be a good test if anyone else is using either of those software suites.
    If you open a terminal window and type kextstat, you will be shown a full report of kernel extensions that exist on your machine. Towards the bottom of the list parallels and/or vmware will be listed if they are installed.
    Hope this helps. Though I am still wondering if Leopard is the problem.
