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.

  • 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.

  • In my macbook pro hdmi, usb & SD card reader not working

    In my macbook pro hdmi, usb & sc card reader not working.
    i have tried the SRM reset done, till not working started.
    Could you please resolve this problem,

    Welcome to Apple Support Communities
    Simply take it to an Apple Store or reseller if it's in warranty. Your Mac will be repaired or replaced for free because it looks a hardware problem rather than a software issue.
    If it's not in warranty, hold Command and R keys while your MacBook is starting up, and reinstall OS X. If it doesn't work, you can't do much more to solve the problem

  • Dvcpro hd and Macbook pro intel duo core

    Hello friends, I have MBP 15" duo core 2ghz ,2gb ram, can i edit dvcpro hd material in fcp studio. i mean will my MBP be able to take the load i plan to use express card, e-sata drives, or do i have to transcode it to dv format. it will be only 1 layer track.

    If you use a e-sata express card with a external e-sata HD, then you will have enough performance. A e-sata drive will be just as fast as your internal drive.
    Maybe if you have a nice 3.5 inch e-sata HD you will have better performace then the internal 2.5 inch laptop HD.

    Hello EMMANUEL JOHN
    When you power on your MacBook Pro, hold the Option key and you should get the Startup Manager that will show you anything that is bootable. All you have to do is select the start up drive and you are good to go.

  • Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

    My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
    I have had this working previously but at the minute it seems to not be playing ball....any thoughts
    Thanks

  • MacBook Pro 13" Late 2011 - Internal Microphone Not Working

    Hey everyone, I've been having trouble with my internal microphone on my 13" late 2011 MacBook Pro every so often. In the Sound preferences, Internal Microphone (Built-in) has been selected on the Input tab, the input volume is on full and the audio port has been set to Sound Output so the internal mic is the only input source. However, there is no signal detected by the input level bar. There's also no input on Skype, which is the main thing I use the internal mic for. I do have an external microphone by means of a headset, although I have to set up a small mixer to have a headphone and microphone input and this takes some time, which I do use but sometimes, for convenience, I'd rather just be able to use the internal mic and use some headphones in the built-in output.
    I can't figure out why it doesn't seem to activate, usually a restart activates the mic but I haven't had much success doing this today, and really, the mic shouldn't be doing it in the first place.
    If anyone can shed some light onto this, please do!
    Thanks in advance,
    LiamWatson28.

    You may try a PRAM reset.  If that does not resolve the issue, make an appointment at the Apple store Genius bar.

  • Macbook Pro 10.7.5 internet will not work. HELP!!! Ethernet and WIFI both say connected but still no internet.

    I have a macbok pro running 10.7.5. My internet has always worked on it but I decided to try changing my router set up - the set up didn't work so I reverted back to the original setup that had previously worked.
    Now, I have an Imac running tiger - I can connect to the internet via WIFI or Built In Ethernet with no problem.
    When I try to connect to the internet on the Macbook Pro running osx 10.7.5 my internet will not work
    Safari Says (You are not connected to the internet) and Google Chrome says (Page is Unavailbe) and lists some trouble shooting options that I tried.
    When I go to System prefrences > Network my WIFI and Ethernet both say "Connected" and have a green light next to them.
    I have tryed deleting the connections and starting new ones and I have even tried deleting the Location and starting a new one.
    Nothing works - no matter what I do, even know the WIFI or ETHERNET says Connected, the internet will not work on the Macbook Pro.
    The Internet works fine on my Imac and I have tried everything such as swaping cables but there doesn't seem to be a problem with my internet
    or with my router - it all works fine with my Imac running Tiger.
    Can anyone help me get my internet working on my Macbook Pro again? Any ideas?

    Hello ASGR.SYS amd WahWar,
    I tried both of your suggestions and neither of them worked.
    ASGR SYS - When I tried it your way i got a message saying that the that the diagnostic couldn't repair the problem. It shows the thw WIFI, WIFI SETTINGS, NETWORK SETTINGS, ISP, all turn green. But the Internet and Sever stay red. The thing is, there is nothing wrong with my internet connection as I can connect to the internet on my Imac running tiger, both through ethernet and wireless. When I go to System Prefrences and Ntwork the WIFI and ETHERNET both say "Connected" even know I can't veiw any websites.suggestion
    When I tried WAHWAR's suggestion I get a message that says cannot connect to the WIFI network and then it lists your typical trouble shooting tips. Like Make sure you entered the right password and make sure you are in range of the wireless network
    Again, just to confoirm - My internet connection is working fne both the WIFI and the Ethernet. When I use it on my IMAC running tiger, everything connects as it should and it works perfectly. But when I try to connect with the MacBook Pro, Even know the connections in the Network settings window show up as "connected" the MacBook still seems to think that my internet connection isn't working at all.
    I have tried creating new connections, creating new locations, and I have even gone as far to reset my router and start completely from scratch. The result so far has been the same - the IMAC running tiger will connect - my blackberry and iphone will connect - but the macbook pro running lion will not connect..
    I'd apprechiate any other suggestions

  • 5.1 Surround Sound Macbook Pro via Toslink to AV Receiver not working

    I cannot seem to get anything other than stereo out of my MacBook Pro, running Snow Leopard, via toslink to my AV receiver using VLC to play MKV's ect.
    I have opened Audio MIDI Setup, selected 'Built-In Output', 'Digital Out', '48000.0Hz', 'Encoded Digital Audio' and then 'Configure Speakers'. On the 'multichannel tab', I then clicked 'stereo' and am now unable to select '5.1 Surround' (desired option) or any other surround option (all options are greyed out). It's as if only my two fronts can be detected, but not the others in my 5.1
    I have seen similar problems posted elsewhere, but none with 'not being able to switch from stereo to surround within Audio MIDI Setup'.
    If anyone could help it would be greatly appreciated.
    All the best,
    Sam

    You ever get this figured out Sam? I'm running into the exact same issue.

  • Macbook Pro won't boot up, recovery not working

    A few days ago my macbook pro crashed. it was being unresponsive for about 5 minutes so i turned it off and on again (ive done this a lot). except this time when i went to turn it back on i saw the grey folder with a question mark on it. i looked a lot into what to do but am currently stuck because i have tried everything ive seen and nothing has worked.
    i went into internet recovery holding option when starting up because internet recovery was the only option it provided.
    i have tried to install a new copy of OSX but when i get to the screen where it asks where i want to install it to, there are no locations for me to chose from.
    i have tried going into disk utility but it doesnt give me the option to select my main disk, only the recovery one it just downloaded.
    it seems that the computer is completely disconnected from the operating system.
    I believe the problem might have something to do with me going a long time without updating software (i know it's stupid but i have a hatred for constant updates when the version i use works just fine)
    I need to keep my files from this computer, it is absolutely crucial that my hard drive is not wiped.
    is there a way to back up my files from this stage? i don't have a backup from before it crashed (sorry for not expecting my computer to just fail on me)
    I have had this computer for less than a year.
    so the main thing I need is to recover my files, even if it requires physically taking the hard drive out of the laptop to recover them on another computer.
    any help is appreciated, thanks.
    (p.s. I forget exactly which OS it was on, but i believe it was Mavericks, not sure which version of it)

    The symptoms that you are describing indicate that your internal HDD has died.  Your data may be lost or require professional recovery services to retrieve.
    Enter the serial number (on the bottom) of your MBP here and post back the model information:

  • MacBook Pro doesn't start - harddisk is not working

    I am desperate. My girlfriends MacBook Pro unibody, with OS Leopard doesn't start any more. It shows the grey screen with the apple, but that's it. I tried resetting the NVRAM - it didn't help. I tried starting in Safe Boot mode - it didn't start. I have booted from the installation DVD and run Disk Utility, but it doesn't even see the partition and all the buttons to Repair or Verify the disk are grayed out. And the System Profiler doesn't see the disk, but instead just gets stuck while trying to read it.
    After all this I did a deep Hardware test, but it didn't find any problems.
    I suppose then that the partition, but not the harddisk is corrupt... any ideas?
    And one more question: is there a way to save the data from the harddisk before trying to erase and reinstall the system, or taking it to the service?

    Try putting it into Target mode...
    http://support.apple.com/kb/HT1661
    To try to read it's drive, or put another Mac with Firewire & a comparable OSv in T mode, hold the Option key down when booting the MBP to see if it'll boot off the the other Macs drive.
    Long shot, but...
    Either boot this one in Target mode...
    http://support.apple.com/kb/HT1661
    And recovering from another Mac, or booting this Mac from another HDD, then using Data Rescue...
    http://www.prosofteng.com/products/data_rescue.php
    (Has a Free Demo to see if it could or not, but you'll need another drive to recover to).

  • MacBook Pro Retina USB 2.0 devices not working in right side USB port

    4 days ago I bought MacBook Pro Retina 15".
    When I plug USB 2.0 device to right side USB port, it does not work. OSX does not recognize it, iPhone does not charge, and so.
    When I plug the same USB 2.0 device to left side USB port, it works.
    When I plug USB 3.0 device to left or right side USB ports, it works without a problem.
    Does anyone have this same issue? How did you resolve it?

    I have a similar issue with a 13" Retina. Both my ports work OK for most USB devices but the right one won't work with a USB external HD (Time Machine backup). Very consistant.

  • Suddenly disconnection with my macbook pro. Resetting my connection did not work because of not accepting my correct password

    During surfing on the net suddenly my wifi connection disappeared. I tried to reswet my connection in the system preferences. Via the airport diagnose the system asked my password of the airport extreme. Giving th correct password the answers was incorrect password.
    Trying many times again no correct solution found. At the end I took the electricity from the extreme airport and started up again.
    After the reconnection and the green operating light was visable the wifi operated complete correct without any resetting procedure and was surfing on the net normal possible. What could be the reason for the suddenly disconnection?

    Update:
    I was able to fix my issue by using the lightning to 30 pin adapter cable. I initially connected my iphone 5 to the macbook pro by using the old usb cable, and the lightning add-on. Once i noticed that a connection was initiated, i then used the new usb cable and attempted to connect it to the macbook. This process worked for me, and i hope it does for you too.
    Thank you

  • MacBook Pro running amazingly slow (formatting DID not work)

    I own a MacBook Pro with OS X installed on it, and it suddenly started running very slow.
    It happened literally overnight. One day it was working, the next morning it wasnt. I tried formatting the hard drive via the disk utility when starting the MacBook, but it didnt work. I also tried to delete my Windows partition, but it didnt allow me (though I dont believe that is a problem, since the last time I used it was over a year ago).
    Anybody has any ideas?
    Thanks for your help,
    Andre.

    Suggestions of Things You Can Do To Help A Slow Computer
    If your computer seems to be running slower here are some things you can do:
    Start with visits to:     OS X Maintenance - MacAttorney;
                                      The X Lab: The X-FAQs;
                                      The Safe Mac » Mac Performance Guide;
                                      The Safe Mac » The myth of the dirty Mac;
                                      Mac maintenance Quick Assist.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    Repair the Hard Drive - Lion/Mountain Lion/Mavericks
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
    Suggestions for OS X Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
              Mac OS X Snow Leopard and malware detection
              OS X Lion- Protect your Mac from malware
              OS X Mountain Lion- Protect your Mac from malware
              About file quarantine in OS X
    If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
    Troubleshooting Applications
    I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
    If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
    1. A Time Machine preferences panel as part of System Preferences;
    2. A Time Machine application located in the Applications folder. It is
        used to manage backups and to restore backups. Time Machine
        requires a backup drive that is at least twice the capacity of the
        drive being backed up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Get Backup
      3. Deja Vu
      4. SuperDuper!
      5. Synk Pro
      6. Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
    Referenced software can be found at MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Pre-Mavericks
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Mavericks and later
    Open Activity Monitor in the Utilities folder.  Select All Processes from the View menu.  Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
