Key board does not light up anymore?

I finally purchased a new mac book for my birthday a few months ago in May of 2013.
Just last night while trying to do my homework in the dark i noticed my keyboard doesn't light up anymore...I went to my settings and launch pad and every thing and still no lit key board please help..I spent every dime i had on this computer and I want to use every function on my device ..plus im disabled...

Morning pimpahrella,
Thanks for using Apple Support Communities.
The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
For more information on this, take a look at this article:

Best of luck,

  • Ipad sounds is not working, for instance key board does not click anymore

    My iPad's sounds are not all working properly.  For instance, I can watch video clips and hear everything, but some apps do not play sounds or when typing on the keyboard, no clicking.  The noise it typically makes when  you plug it in to charge is gone as is the click sound when opening the screen.  Can anyone provide any help or insight as to what may be causing this?  I have looked in settings/sounds and all is correct.
    thank you.

    Is Settings > Sound > Keyboard Clicks ON?
    Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)
    Note: You will not lose any data.

  • My wireless key board does not work but wireless mouse does?

    I can not get my wireless keyboard to work again after i changed the batteries, It work sonewhat before I chaged the batteries but don't work at all now. I tried removing the thing pluged into the usb port and i pushed the connect button on the bittom of keyboard but nothing works. The wireless mouse works fine. What could be wrong?

    Not sure which KB you have, but I'd check a few things.
    1) You might have a dead battery or two - perhaps try batteries known to be working in another device, such as a TV remote control.
    2) The KB shouldn't need to be re-synced just via a battery change.   However, if you do resync - you might need to hold the sync button longer.   On my TouchSmart IQ804, I usually push mine about 10 seconds or so.   I can pull the USB tranceiver out of the back of the unit and put it in the side/front port, that way I can watch the LED that indicates sync/transfer better.
    I know that there are some good wireless KB troubleshooting documents on the HP website - here is a link to one of them.

  • Inconsistancy of illuminated key board in low light conditions

    I have several accounts on my power book and my administrator account has onyl a dim key board in low light while the other accounts have a bright light. I have checked to turn this function on under keyboard preferances. Does anyone know what I can do to get this to work in my account. It does not seem to be a hardware problem, since it works fine in other accoounts. is there any function which controlls the brightness of the keys in low light conditions???

  • Key photo does not sync

    I have a Mac Mini.  My photos are stored on an external hard drive.  I import them into iPhoto.  When I sync to my iPad the key photo does not show anymore.  This has only just started.

    Upon further study the problem runs deeper. There is not much syncing going on at all. This mobile me sync business is confusing. I've turned syncing back on, reset contacts in mobile me (supposedly) with contacts from my computer, but the test contacts I made online in mobile me remain there. The photos and I believe other changes do not appear either. I don't think mobile me is updating. Something is broken that's for sure.

  • Pavilion DV6 1311el power supply ok, power led does not light up

    I own a dv6 notebook model 1311el that works just fine with a charged battery but it wont accept charge from the charger. The led next to the power jack does not light up, i have removed the power button bezel and keyboard and then i used a multimeter to measure the voltage between the wires of the power jack cord and there were 19.5 and 15 volts as it should... I am sure that the power supply works because i gave it to a friend of mine which has the same hp model.

    Hello Nessuno,
    I see your AC adapter is not charging your HP Pavilion dv6-1311el Entertainment Notebook, your battery indicator LED is not lit. I would like you to start here, this will help you determine if it is the battery or the power supply: Battery Does not Power Notebook or Hold a Charge.
    A battery that does not charge might be the result of a power adapter failure, a system board failure, or a battery failure. Please perform the steps listed in the troubleshooting document in order to diagnose the failure.
    I hope this is helpful.
    Thank you,

  • Ipod does not light up when connected to PC.

    My ipod used to light up when you touched the clickwheel when it is plugged into my computer, but ever since it showed a folder with a exclamation point (which i fixed) it does not light up when it is touched on the clickwheel anymore. I have restored it a coupple times and my ipod is up to date (1.1.1), does anyone know why it is doing this?

    Does anyone know?

  • I recently go my screen replaced and it has worked since then. But now all a sudden the screen does not light up. I know my phone is on because Siri is still responsive if I hold the home button, I just can't see anything. Any suggestions?

    Most likely the LCD Display connector simply came loose from its logic board connector. Take iPhone back to where it was repaired, and ask them to simply press the connector back into its place. Ask them to apply a bit of foam material or several small pieces of tape on top so the pressure of the flex connector plate holds it properly in place for the future.

  • Delete records in itab1 where key fields does not exit in itab2 w/o Loop

    Hi,
    I am trying to find the most efficient way to compare two internal tables and filter out (delete) the entries in Internal Table 1 (ITAB1) where the key fields does not exist in internal table 2 (ITAB2).
    Here is the codes using the Loop.
    Loop at itab1.
      read table itab2 where field1 = itab1-field1 and field2 = itab1-field2.
      if sy-subrc ne 0.
       delete itab1 where field1 = itab1-field1 and field2 = itab-field2.
      endif.
    endloop.
    Instead of looping thru each record of ITAB1, is there a way to use the "DELETE" or other efficient way? This is in ECC 6.0.
    Thanks for any advice in advance.

    Not sure if its possible without using even a single loop. Though you can avoid the read statement this way
    loop at itab2.
    delete itab1 where field1 NE itab2-field1 and field2 NE  itab2-field2.
    endloop.

  • HT1459 Just bought a new ipod shuffle for my kid and cannot set it up because it does not show up in itunes. Also the charging light does not light up. what could be wrong, as i am able to see both my iphone and ipad on itunes on the same pc?

    Just bought a new 4th gen iPod Shuffle for my kid. Problem is I cannot do the initial set up, as the device does not show up on iTunes on my PC. Also the charging does not light up. Any ideas on what could be wrong, as I am able to see both my iphone and iPad on iTunes using the same PC?

    I also tried manually underlining a few things on the new iPad and when highlighting a paragraph, it would skip a few lines and the line would go through a few as well. Looks like a major iBooks glitch needs to be addressed here.

  • "The key 'LocalizedPerfCounter' does not exist in the appSettings" when creating Socket

    Hi all,
    Some time ago, I've installed the nuGet package for self-hosted signalR applications on a project. Today, I went to start a completely unrelated project, one that does not have that package (or any package at all), and has absolutely nothing to do with owin,
    asp.net, signalR or anything else related to that package.
    Now in this project, when I try to create a Socket, I get an InvalidOperationException: "The key 'LocalizedPerfCounter' does not exist in the appSettings".
    The exception seems to be handled and the program proceeds, but it's annoying.
    Also, I'm seriously concerned. Here I'm not trying to create some arcane ASP.NET thing that calls down into a dozen layers and six different configuration frameworks before actually getting to the TCP stack. I'm doing a plain straight new Socket(AddressFamily.InterNetwork,
    SocketType.Stream, ProtocolType.Tcp).
    How is it possible for a nuGet package that installs unrelated DLLs to another solution entirely to affect something that resides in the basic System.dll? What business does it have interfering with very low-level network calls?

    Hello Zappo,
    For this InvalidOperationException, please check this hotfix to see if you are under those scenario:

    Hi... I would like to purchase a Tablet Sony Xperia Z 2 10.1 (the last one of the Z series) and I was told that Adobe does not support Sony anymore.... I need to be able to open and read Adobe PDF files and I would like to know if this tablet can still use Flash Player...
    Is there anyo who can help me with this? I asked in the shop and I was told "yes of course" , but when I contacted Sony directly I was advised to check with Adobe as apparently in the recent months Adobe and Sony haven't been getting along anymore...

    You may be mixing up two entirely different Adobe products.
    1. Adobe Flash Player. Needed to view web pages designed with Flash. Not needed to view PDF files. Not available for Android (not just Sony).
    2. Adobe Reader. Reads PDF files. However, the Android can also read most PDF files without needing Adobe Reader.

  • REP-52005: The specified key userlogin does not exist in the key map file.

    Hi,
    I am using oracle 11g report server. I am getting the error of REP-52005: The specified key userlogin does not exist in the key map file.
    I updated the user_string in cgicmd.dat file. My cgicmd.dat file content is below
    ; OracleAS Reports Services                       ;
    ; CGICMD.DAT                                      ;
    ; Example CGICMD.DAT Mapping file                 ;
    ; Syntax: 
    ;      KEY : VALUE
    ; Where:
    ; KEY - the first argument of the rwservlet URL request (case sensitive).
    ; VALUE - command line parameters and/or special parameters.
    ; Keys can be referenced in the following ways:
    ;    1. Parameter on command line to the reports servlet
    ;          e.g. http://machine/servlet/rwservlet?KEY
    ;    2. Parameter on command line to a reports jsp
    ;          e.g. http://machine/mydir/myreport.jsp?KEY
    ;    3. Within a reports jsp - in the rw:report custom tag
    ;          e.g. <rw:report parameters="KEY">
    ; In addition to the Reports Server command line parameters, VALUE can include special parameters
    ; represented as "%X", where X identifies the parameter. Currently recognized special
    ; parameters:
    ;  %0 - %9 - 0..9 arguments from original rwservlet URL request. Note that %0 refers to the key itself.
    ;  %* - entire contents (all arguments) of original rwservlet URL request.
    ;  %D - request users to input database userid everytime they run the report.
    ;  %P - request for report parameter form in HTML format. It generates the PARAMFORM=HTML
    ;       construction on the first submission of the URL and PARAMFORM=NO upon parameter form submission.
    ; CGICMD.DAT Usage Notes
    ;   1. Multiple keys in this file MUST be separated by an EXTRA empty line.
    ;   2. Extra spaces are ignored. Multi-line entries allowed.
    ;   3. Lines starting with ";" character are treated as a comments.
    ;   4. Comments within a key or key value are NOT allowed.
    ;   5. NLS language support is provided and can be used (encoding should match the one
    ;      used in HTML request - no language conversion of any kind is attempted.
    ;   6. For %P special parameter, HTML format is by default mapped to the HTMLTABLE format in this release.
    ;      The HTML format in the future may be mapped to the HTMLCSS format.
    ;;;;;;;;;;;; Example Key Entries
    ;  Example 1:  Run a simple breakb report and output to HTML
    orqa: report=breakb.rdf destype=cache desformat=html server=repserver
    ; Example 2: prompt for userid the first time, then use database userid stored in the cookie subsequently.
    report_defaultid: report=breakb.rdf destype=cache desformat=html server=repserver
    ; Example 3: use %D to require user authentication every time
    report_secure: report=breakb.rdf destype=cache desformat=html server=repserver1 %D
    ; Example 4:  Take all arguments from URL and send it to the reports server
    run: %*
    ; Example 5:  Run breakb report with HTML parameter form.
    breakbparam : report=breakb.rdf destype=cache desformat=html server=repserver userid=scott/tiger@mydb %P
    ; Example 6: take all URL arguments, and also generate a HTML parameter form  
    runp: %* %P

    Please help me to to make the key being populated here and being used by the reports server.
    Thanks,

    uncomment #KEYPMAPFILE=CGICMD.DAT. remove the #
    then for development set
    reloadkeymap=yes (same file - rwservlet.properties).
    Now it should reload everytime. (otherwise for every change u need to restart oc4j_bi_forms)
    (For * production* may be you want to set reloadkeymap=no once all testing is done)
    see cgicmd.dat for many examples of using keymap file
