Macbook 13 Retina keyboard backlight not turning on

Hi all,
I've had my 13inch MPRr for about two weeks now and whenever it comes out of sleep from a LidOpen the keyboard backlight will seldom turn on.  It is pretty inconsistent but I can usually get it activated again when I put it into sleep manually from the menu bar.  Has anyone else experienced erratic behavior from the keyboard backlight?

I'm also experiencing this problem. my 2.6 macbook pro is less than 2 weeks old and the backlit keyboard stopped illuminating a few days ago. it DID work for a time, but suddenly decided to stop working. labtick and preference pane tweaks have done nothing to fix the problem.
Try resetting your SMC, PRAM and run your hardware tester.

  • Macbook pro (retina) keyboard backlight not working after Yosemite update

    Help,
    My keyboard backlight stopped working when I upgraded my Macbook pro (retina) from Mavericks to Yosemite. Nothing in System Preferences -> Keyboard makes a change. This is a feature I use a lot. Any help will be appreciated. Thank you. 

    Try a SMC reset:

  • Macbook pro retina keyboard backlight always on

    My new MacBook Pro Retina keyboard backlight always on under room light?
    I've to turn it off manually.
    But if under sunlight, it doesn't lit which means the ALS is working, may be just not that sensitive enough under ML.
    ML problem ?
    I saw those display set at retail is working under room light but running Lion not ML.
    Is ML really have problem ?
    Should I reverse to Lion ?

    No need to revert back to Lion.
    May be resetting SMC will help.

  • Macbook pro retina heating and not turning on

    So I got my new macbook retina 15 inch around 4 weeks ago and it has been working fine, next day
    I got it plugged and nothing, the screen just didnt start it was all black, so I plug the charger and the indicator
    just seem fine but after 1 hour this computer has a massive heat all over the keyboard and the backplate where
    the battery is, I guess, so I disconnect everything but the heat starts to get even hotter so Im kinda worried the thing
    is going to blow etc etc, that was around 7 pm, So i went out and let it cool a bit, came a few hours later and bam
    there it is working again, just plain weird behavior of this new machine so I wonder what the heck happened?
    what am I to expect again from this? anyone had this before, and is there some kind of app to monitor
    the heat levels or make a complete diagnostic?
    thanks in advance if you might know something useful.
    Andrew.

    Hello blackhemiangrove and welcome to Apple Support Communities,
    "am I to expect again from this? anyone had this before, and is there some kind of app to monitor

    You shouldn't have to even worry about something like this. Document what happened and take it back to Apple immediately and make them fix it.

  • Macbook Pro Retina 15" won't turn on.

    Macbook Pro Retina 15" won't turn on. The charger light is orange. I tried all tips that Apple provides on the official site -  http://support.apple.com/en-us/HT204267. Any ideas?

    If you purchased it from Apple directly, they have a 14 exchange or refund policy.  Keep that in mind when you go to the store.

    Macbook Pro Retina Display does not respond. Any fixes? I wonder if it overheated and shut down. Anyone else had a problem?

    Kitsi,

    Also found the combinations buttons fn-control-F7 to unfreeze.
    good luck

  • My MacBook Pro (Retina) laptop does not recognize my HP printers

    My MacBook Pro (Retina) laptop does not recognize my HP printers. HP only has updates but not full drivers for Mountain Lion. Some articles say the compatibility might only allow me to print, but the scan feature won't work. I am attempting to use either my HP Color Laser 2840 and my HP Photosmart 209-B printers. I tried to reinstall the printer drivers, but HP doesn't have drivers to download for Mountain Lion OS.
    Anyone else have this issue?

  • Macbook keyboard backlight auto turn-on when room is dark?

    I have a late 2013 13" Retina Macbook Pro (running Mavericks) and am a relatively new OSX user. I know that I can modify keyboard backlight settings and have the brightness level adjust automatically (similar to how the screen brightness adjusts) however I don't actually want the keyboard's backlight on when the room is light. The fact that the auto-adjust setting makes the keyboard brighter in a light room is annoying to me.
    Is there any way to have the backlight automatically turn on ONLY when the room is BELOW a certain brightness threshold. Perhaps there is a 3rd party app that can add this functionality? Manually pressing F5 and F6 works fine, but ideally I'd like to have this automated somehow.
    Thanks!

    Billy_budd,   Unfortunately it's not even that things are finicky for me. I haven't experienced any auto-turnon functionality at all. Are you running Mavericks? I've seen some older posts referring to this being a possibility. Is there a specific way you've enabled this option? I don't see anything in my settings.
    If I select the tickbox I've highlighted in the screenshot below, the brightness of the keyboard mimicks the auto-audjust behaviour of the screen's backlight. With it unchecked, I have to use F5 or F6 to see any keyboard brightness changes. I haven't experienced the keyboard automatically turning on when the lights turn off.

  • Keyboard backlight not working - settings missing on MacBook 2,1??

    I have a macbook 2,1 that was given to me by a friend about 6 months ago. It is in perfect condition except some seperation around the edges. So, I took into the Apple store a couple of days ago and they replaced the entire 'inside' of the macbook; meaning screen surround, keyboard and surrounding 'faceplate'. (Excuse the incorrect terminology) I also mentioned to them that the keyboard didn't have any backlighting (at least I have never seen it) and the tech said would also be repaired as a result of the keyboard replacement.
    ANYWAY, I am home and the keyboard backlight is still not working. I searched mac help and found the following:
    To set keyboard backlighting for a portable computer:
      Choose Apple menu > System Preferences, click Keyboard & Mouse, and then click Keyboard.Open the Keyboard pane of Keyboard & Mouse preferences
      To enable backlighting, select the “Illuminate keyboard in low light conditions” checkbox.If you want to automatically shut off the backlight when your computer is idle, drag the slider to indicate when to turn it off.
    The only thing I saw was an option for bluetooth - n/a, keyboard shortcuts settings to change shortcuts..obviously and the keyboard setting which only gives me the choice to
    1. change the key repeat rate 
    2. change the delay until repeat rate and 3. a box to check/uncheck if I want to use the f1, f2, etc as the standard function keys.
    There is also a button at the bottom left corner which says 'modify keys' which I believe is n/a.
    I should also probably mention, when searching help, it also said "The light sensors are located in your computer’s speaker grilles, so make sure the grilles are not covered when you use your computer in low light conditions" . I have no speaker grilles (that I can see) but my speakers work. and it says; "IF the keyboard on your computer can be backlighted, you can set it so the keys can be visible in lowlight conditions". I guess the keyword here being IF so maybe this mac isn't supported for that but I think that it is from what the person at the Apple store told me after looking up my serial number.
    Just to add, I did search the forum and found close to the same problems but with different types of macs so I thought I would ask. I am still learning the ins and outs of using Mac so I hope I asked the right questions and I'm not over expanding on the question too much.
    I am sure there is a simple explanation...maybe?! So if someone could enlighten me, I would be very grateful!!!!
    Thank you!!!!

  • MacBook Pro keyboard backlight not switching off

    I recently bought a 13" MacBook Pro (2012, 2.9GHz i7) and it came with Mountain Lion preinstalled. The keyboard backlight isn't behaving as I had expected: when the "Adjust keyboard brightness in low light" option is checked, it does indeed adjust the brightness of the backlight when ambient light levels change. However even when the ambient light is VERY bright (desk lamp shining down) the backlight doesn't switch off; instead it just goes to full brightness. I understand that the backlight usually dims in dark conditions to save battery, but why would it go bright when the keyboard is fully visible without a backlight? Is there a way to make the keyboard backlight go off when there is plenty of background light and come on when the environment is dark?
    Thanks in advance for any advice.

    Auto brightness operation usually works in the way yours is working.  It is dimmer in very low light and progressively gets brighter as the ambient light increases.  There are cases where this is actually helpful as in wierd backlighting situations.
    You can override in the System Settings and from the keyboard "function" keys.  I'm not at my MBP right now, but I think the keyboard backlighting controls are somewhere near F5 and F6.

  • Problem with Macbook Pro early 2011, webcam not working in any apps and windows 7 or 8 on bootcamp, keyboard backlight not working?

    Hi Guys
    I recently bought a second hand early 2011 Macbook Pro 15 inch and are having 2 problems. The first is that none of the apps detects my webcam at all, the second is, i have Windows 8 installed on bootcamp but are unable to get the keyboard backlight to work in 7 or 8. The backlight works perfect in os x 10.8.5 though. I need a little bit of help guys.....

    Go to Apple Menu / About This Mac. Click on More Info ... next on System Report. In the left hand column, under Hardware, select USB. The right side will show the USB Device Tree. Look through that and check for "Built-in iSight". That is your camera. If it is not listed the camera is not working.
    For backlighting, try this: go to System Preferences / Keyboard. Uncheck "Adjust keyboard lighting in low light".
