Why won't my display backlight come on?

I have a unibody MacBook Pro purchased in late 2009.
Sometimes when I wake up my laptop I can see that the display has come on but the backlight that makes the display bright is not on.  On other words, the screen is completely dark, but under the right lighting I can see that the LCD itself is on (windows are up, the cursor is moving around the screen) but there is no light making it all bright (i.e., the display backlight is off).  When I put it to sleep and wait for the indicator light to start pulsing and then wake it up again it will off then come on, but of course I shouldn't have to do that.
Perhaps related or unrelated is my keyboard backlight also doesn't work.  I can turn the brightness up and down using the F5 and F6 keys and the indicator will come up on the screen showing the brightness going up and down, but the keys themselves are not lit at all.
Was there a recall sent out about this issue?  I do have AppleCare.
Thanks.

I have the same thing, not only my current Retina MacBookPro (Mountain Lion) but on my previous 2008 MacBook black (Lion). I find it very odd that I'd have the exact same issue on two different computers; there must have been a setting on the old one that got migrated to the new one somehow?

  • Why won't my g4 desktop come on. I was trying to boot in safe mode and it would not go in safe mode. It won't come back on anymore. Can some tell me what to do.

    Why won't my g4 desktop come on. I was trying to boot in safe mode and it would not go in safe mode. It won't come back on anymore. Can some tell me what to do.

    Try Single User mode (Command+S while starting up).
    Then, run fsck.
    At the command-line prompt type:
    /sbin/fsck -fy
    Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
    ** The volume (name_of_volume) appears to be OKIf fsck found issues and has altered, repaired, or fixed anything, it will display this message:
    ***** FILE SYSTEM WAS MODIFIED *****
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    When fsck reports that your volume is OK, typerebootat the prompt and then press Return.
    Your computer should start up normally and allow you to log in.

  • Why are my Add-on Bar items halfway hidden, and why won't they display properly?

    [http://download343.mediafire.com/29kbvy9b609g/uzw78f3vqf688mb/Add-on+Bar+Glitch.PNG Glitched Add-on Bar photo]
    After using the new Firefox 4 for just a few days, I've noticed that my Add-on Bar items (mail notifier and weather bar) are jutted down below the actual visible display area they should be, so I can see half of the icons. This is not a priority issue, but it is still an issue, and it bothers me. I've already tried uninstalling then reinstalling Firefox 4, I've already tried removing then reinstalling the add-ons themselves, and I've also tried just hiding then showing the Add-on Bar but still nothing is changed. This problem only occurs when I use themes for Firefox 4 other than the default theme. The attached photo is a screenshot of my Add-on Bar so you hopefully won't think I'm crazy.

    I've figured this out. Apparently, there is a graphical bug in FF4 when the "Show: Icons and Text" option under customizing the toolbar is enabled, and the Downloads icon is in the Add-on Bar, the Downloads icon remains centered, but the other items in the Add-on Bar are pushed under the display area of the Add-on Bar. If the setting is reverted back to just icons or just text shown, or if the Downloads icon is removed from the Add-on Bar, this is fixed. A simple line of code could fix this coincidental error, but as I said before, it's not a priority issue. As always, I can just click Ctrl+J to show my current downloads. I just tried to have this icon in the newly named Add-on Bar to replicate my old-fashioned Firefox 3.6 interface, but I guess that's unreasonable for Mozilla...

  • Why won't List display ArrayCollection?

    Hi all,
    I cannot for the life of me figure out why the List I created will not display any of the values in my ArrayCollection.  I've read and watched so much databinding material, that I think it must be something extremely small or absolutely huge that I'm missing.  If anyone could give me a pointer or two it would be so greatly appreciated, I've been on this for days now.
    I have two .mxml's (MyCards and NewCard).  The idea is that in the NewCard View the user types in a Title, and text for side 1 and side 2 of a flash card.  The program then saves all 3 of these properties into an Object and puts that Object into an ArrayCollection.  This ArrayCollection is display in a List in the MyCards.mxml file.  The problem is, nothing shows up.
    Here's part of MyCards.mxml showing how I'm implementing and binding the ArrayCollection to the List:
                        [Bindable]
                   public var card:Object = new Object();
                   public var nc:NewCard = new NewCard(); // create new instance of NewCard
                   [Bindable]
                   public var cards:ArrayCollection = new ArrayCollection();
                   public function add():void
                        cards.addItem(nc.myCard); // add new Item to ArrayCollection 'cards'
                        trace(cards.list);
              ]]>
         </fx:Script>
         <s:actionContent>
              <s:Button label="Delete"/>
              <s:Button label="Home" click="button1_clickHandler(event)" skinClass="skins.homeButtonSkin"/>
         </s:actionContent>
         <s:Image x="0" y="-80" height="603" source="mainapp1.jpg"/>
         <s:List id="myCardsList" x="10" y="10" left="0" right="0" top="0" bottom="0" width="1004"
                   height="500"  dataProvider="{cards}"
                   enabled="true" >
              <s:itemRenderer>
                   <fx:Component>
                        <s:MobileItemRenderer label="{data.Title}"/>
                   </fx:Component>
              </s:itemRenderer>
              </s:List>
    And then here's how I'm 'adding' the cards in the NewCard.mxml:
                             [Bindable]
                   public var myCard:CardVO = new CardVO(); // create new instance of CardVO
                   public function button2_clickHandler(event:MouseEvent):void  // save button
                        var myc:MyCards = new MyCards();  
                        myc.add();
                        trace(myc.cards.list);
                        trace(myc.cards.length);
                        //card.fTitle = titleCard.text;
                        //mycArray();
                        titleCard.text = "Card Added!";
         <s:TextInput id="titleCard" x="240" y="10" height="62" chromeColor="#515851" color="#060606"
                         contentBackgroundAlpha="1.0" contentBackgroundColor="#FFFFFF" text="{myCard.Title}" change="{myCard.Title = titleCard.text}"/>
         <s:SkinnableContainer
              id = "groupt" x="161" y="88" width="703" height="357"  >
              <!-- text property of mtext1 and mtext2 is bound and returned to the get/set functions in CardVO in the 'change' event-->
              <!-- change sets setter values to those retrieved from textAreas-->
              <s:TextArea id="mtext2" visible="false" x="0" y="0" width="703" height="357"
                             color="#000000" contentBackgroundAlpha="1.0"
                             contentBackgroundColor="#FFFFFF" editable="true" enabled="true"
                             paddingTop="70" text="{myCard.Side2}" change = "{myCard.Side2 = mtext2.text}"
                             textAlign="center"/>
              <s:TextArea id="mtext1" x="0" y="0" width="703" height="357" color="#030303"
                             contentBackgroundAlpha="1.0" contentBackgroundColor="#FFFFFF" editable="true"
                             enabled="true" fontFamily="Arial" fontStyle="normal" fontWeight="normal"
                             lineThrough="false" paddingTop="70" text="{myCard.Side1}" change="{myCard.Side1 = mtext1.text}"
                             textAlign="center" textDecoration="none" verticalAlign="middle"/>
         </s:SkinnableContainer>

    The cards array collection items appear to be another list of items instead
    of just items?

  • Why won't tabs display properly when composing e-mails in mail?

    When I compose an e-mail in Mail, often the window won't display the top row of tabs (send, attachment, etc.).  I can see the tip of each graphic, but it's almost like they've been cropped out.  Does anyone know what might be causing this and how to correct it?  Thanks in advance.

    yldawg,
    Try going to the mail menu, view click on hide toolbar, and clicking show toolbar (or visa versa) depending what shows. I haven't used this os in a long time, so I'm not sure how it is set up anymore.

  • Why won't Safari display altered uploaded files?

    If I make some changes in my web page, some changes in CSS setting, and upload the page, it continues to display in the former format. However, if I check Firefox, the newly edited file appears just fine.
    I tried repeatedly emptying the Safari cache, and even used Onyx to empty all browser caches, and of course repeatedly try reloading the page but it still does not update.
    Does anyone know why this is so? Is there a solution?
    Thanks,
    Richard

    You confused me a little here. Earlier you wrote:
    t I can see the changes in GoLive or BBedit (as previews)
    but then you say:
    That I am also previewing the file in Safari and also loading from my hard disk at that time. So that suggests to me, since Safari does not render it right
    Are you seeing changes made to CSS files when previewing in Safari ... or not? I might have read something wrong, but I had the impression you were saying previews in Safari show CSS changes, while previews online do not.
    Also, I think there are two things happening and one is confusing the matter. Earlier you wrote:
    But when previewed in Safari, it is not the same — the padding is gone.
    My feeling was that this was a separate issue, not a problem with caching. (To my knowledge and in my experience, Safari never uses cached files when viewing files on the hard drive.) My thought was that this is a CSS conflict or syntax problem.
    Test for the caching issue (in previews vs. online) with something obvious, rather than your padding style... something like a red border or a text style, so you'll be sure if it's there or not.

  • Why won't my screen saver come on?

    I recently had the hard drive on my MBNP re-formatted and now the screen saver does not come on.  I have made several different adjustments to the Desktop/Screen saver preferences and to the Energy Saving preference and nothing seems to work.  I have set the computer and display to NEVER turn off, I have set the computer to NEVER turn off and the display to turn off in X minutes.  Neither choice sems to work.  Withy both set to NEVER the computer and desktop display justb stays on all of the time.  With the computer set5 to NEVER the display goes black after the set number of m inutes but the screen saver doesn't begin.  I have tried to set it for different possibilities but always get the same result, nothing. HELP please.

    MrRules,
    If in fact you are running 10.7.2, you should run software update to bring it up to 10.7.5.
    You can also try a SMC reset:
    http://support.apple.com/kb/HT3964
    Follow directions for a battery you should not remove yourself/or which applies to your computer
    Also try a NVRAM/PRAM reset:

    Also check your system preferences, energy saver, screen saver, and also check that wake for network is not checked, as well as blue tooth...

  • Why won't my message notifications come up?

    It's not showing I have any messages until I physically go into the message app and then it'll say I have a message. Why? How can I fix this so it'll notify me when I get a text.

    Hello bafficr,
    Thank you for using Apple Support Communities.
    For more information, take a look at:
    iOS: Understanding notifications
    http://support.apple.com/kb/ht3576
    If you're not receiving notifications for a specific app, try these steps:
    Verify that the app supports notifications.
    After installing an app or restoring a backup to a different iOS device, open the app to begin receiving notifications. If the app requires entering or logging in to an account, you will need to do this before receiving notifications.
    Check Settings > Notification Center to ensure that the app is configured for notifications. If notifications do not appear in the Notification Center, verify that the Notification Center setting for the app is enabled.

  • HT1719 ok why won't sync to ipod come on list

    got an ipod shuffle have opened account in tunes and reinstalled things 4 x why can't i get the prompts i need to work it, i'm 2 degrees above computer dumb

    So it sounds like this is the first time you are trying to use this iPod shuffle with this computer...  It has not previously worked.
    If you have been trying to connect the shuffle to a USB hub, I would connect it to a direct port on the computer.  And if you have not already done so since installing iTunes, do a shut down (power off) of the computer.  Use this procedure to reset the shuffle
    http://support.apple.com/kb/HT1655
    Start up computer with shuffle NOT connected.  Run iTunes.  Connect shuffle.
    If that does not help, you should also try disconnecting ALL other USB devices, except for a standard mouse and keyboard.  This is in case there is some USB device conflict.  Then, connect the shuffle to a USB port that is directly on the computer.
    If that does not help, and you have an Apple Store nearby, I would make a reservation at the Genius Bar to have the shuffle looked at.  If it is defective, you can see about getting it replaced under warranty.

  • HT204053 Somehow the very first email I had years ago that I don't even remember the password for, keeps coming up as my apple ID, when I want to make any purchase on ITunes. Why won't my real ID come up, and I can't find the right solution?

    Does anyone know how to eliminate a mistaken apple ID that you still use as an email
    but for some reason, now when I go to make a purchase at ITunes, it  brings up this email
    as my apple ID instead of my actual Id and it will not take the current password I have for
    this email. Somehow I believe it is confused, because years ago this was my first email, and
    it had a different password way back then, that I no longer remember.
    I am very sorry if this all sounds confusing, but my Mac book has been out of commission for the
    past year, and I have been recently trying to work on it, and I am not suave on the computer at all, so
    if my next question sounds lame, you'll know why... I wondered if that may have caused any of my
    latest hitches, only because when I first purchased Mac, 4 years ago, this rogue email was the one
    I signed up with everything on my Mac, but I have not been using it for the past 9 months, just my
    iPhone, until that died 3 months ago, and then I got this new I phone 5 2 months ago, thinking my
    problems would be..., a thing of the past,??, for at least a little while??? But NO, they have not,
    However, I'm sticking to the problem at hand, I have a full functioning apple ID that works and at
    some occasional times, ITunes would bring the correct ID up. And only once in a while bring the
    Bogus one up. But in the last few weeks, all it asks for now is the wrong ID and my frustration has
    reached its max!!' I have missed out on purchasing two apps I needed, and some music I wanted,
    and I don't think I'll be able to even use ITunes at all until I can know how to make my devices realize
    that my email is an email, not a apple ID, and then make it accept my real ID!!!
    Without having to eliminate, or delete my email address I still use, and receive mail
    at. Please forgive this lengthy explanation!!!
    I was only trying to make sense, if I confused you
    more, I'm very sorry... Thank you for any brave ones that tackle this, and actually have some
    Solutions for me.., I thank you much indeed!!  Sincerely  Kim

  • Why won't iCal display multi-day events in month view?

    This is frustrating. If someone sends me a calendar event that lasts multiple days from Calendar software that ACTUALLY WORKS  (hint hint hint Google Calendar, Outlook), and if I accept this event, it only displays the FIRST DAY of the event in iCal's month view. It should put a solid bar through every date included in the duration of the event. How is it that this has not been fixed yet???

    Bug or design flaw?
    Try setting it as a recurring event (yeah, I know, it's not a great solution, but it gets the job done)

  • Why won't iTunes display the content tabs at the top of the screen?

    I recently upgraded to iTunes 5.1 so that I can sync my MacBook Pro with my new iPad.  Now I can't figure out how to select and transfer my photo albums - nothing with my photo albums is displaying on the iTunes screen or in the Library.

    So I setup my ipad as a new iPad and even after putting iTunes back on it. If I deselect what I want to sync and then sync again those items are simply not removed.
    You would think after this long that Apple would have the ability to thoroughly regression test this stuff.

  • Why won't GUI display correctly ?? --URGENT--

    Hi,
    I am copying the code from my book. For some reason the color doesn't work when I copy+paste teh code into Eclipse. Am I doing something wrong or do I have to enable something in Eclipse options??? I keep getting 2 windows WITH NO TXT and NO COLOR. Here is the code:

    Well I read the forum rules and it doesn't say
    anything about not using URGENT. Sounds like you are
    going based on convention.Consider basic good manners. You have just approached a bunch of strangers and asked them for their help, for free. By telling us it's urgent, you're really saying "my problem is more important than these other people asking for help", which is only true as far as you're concerned. Everyone considers their own problem more important.
    The forum rules may not say anything about not using "URGENT", but since the people answering the questions have the power to do so or not, you just have to abide by what they say. Like it or lump it, basically. Or cough up some hard currency

Maybe you are looking for
