Keyboard backlight not auto dimming

Just got a new MacBook Air. I have the auto dim option checked in the keyboard settings but the keyboard backlight just remains on all the time.
Any ideas?

First off, very good troubleshooting, it is refreshing to have someone who provides more information other than "it don't work".
I assume since you said no boot key combinations work that it wouldn't boot to safe mode.
You did say you were able to hold option and select the Mac HD, does your recovery partition show up here? Are you able to boot to recovery? Also, are you able to get back into Windows at this point?

My ZAGG keyboard will not auto-cap, How do I fix that?

What MacBook? How did you try to 'play' CDs? What happens? Does it happen with a specific CD, some CDs, or all CDs? Does it happen with data CDs, or audio CDs, or both? Does it happen with commercially-pressed CD, or CD-R, or both?

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.

Keyboard backlight not working...

Hi everyone!
I am having a problem that appears to be shared by other Powerbook users who have the luxury of a backlight for their keyboard: I have updated OSX and now the option of automatic illumination has gone from the Keyboard and Mouse preferences window?
Does anyone know how this can be fixed? I have only had my laptop for 13 months and so far my hard drive has died and the system has crashed completely three times, I would be devistated if this is the logic board now? If you think it is please lie!? Only joking of course, but if anyone has a neat solution I would love to know!
I have already tried to set-up a new user, and have removed the com.applebezelservices.plist from the library, but no joy so far.
I use this luxury lots, since I work at night. Any help would bring festive cheer to me and my children to be!!!
Regards,
Simon

Same problem here with my powerbook 15" 1.5ghz.
It seems that this problem is common with a lot of people as I can see from the forums that I went on.
The ambient light sensor seems defective since a software update (probably the 10.4.7). Results are that the auto-dim of the screen does not work all the time, the keyboard no longer backlight up in dark condition and the sleeping status light blinks for no reason or it stays on when computer is open.
I've tried to zap de PRAM and reset PMU with no results.
I've read that some people has a loose connection between logic board ans ambient light sensor... could that be the reason as you mention taht they told you so?
I've read that some people with the same problem had their Logic Board changed as they were under warranty... but for the rest of us that are not on the warranty anymore... no answers from Apple. I think that they should open a repair ticket and that everybody who has this problem should contact Apple

Bluetooth, iSight and Keyboard Backlight not working. Please help!

My Bluetooth stopped working along with my iSight and Keyboard Backlight. I first noticed the weird sign over the bluetooth icon, and it read "Bluetooth not available". I payed no attention to it for a while until I tried to take a picture with Photo Booth and I read "No camera found", for some reason I tried to dim the backlight on the keyboard and a blocked sign appeared under the brightness level, not letting me do anything (Later I was able to use the backlight with the LabTick app). I have tried everything. SMC, PRAM, NVRAM, logging as diferent and new users, booting in safe mode... every solution I have found on the internet has been tested by me. Then I read this about the Hardware Test solution, and surprisingly after performing the Hardware Test no problems were found! So basically my MacBook Pro (mid 2010) is not having any trouble of any sorts with anything. Then why can't I use Bluetooth, iSight or Key backlighting (which only works through LabTick). Given the fact that the hardware test shows no problems I am not comfortable with the idea of taking it to repair. There MUST be something I can actually do to fix these issues.
Does anybody have any idea? I repeat, these are NOT WORKING, NOT FOUND AND NOT AVAILABLE.
- Keyboard Backlight (Only works through LabTick)
- iSight Camera (Not found by any software)
- Bluetooth (No info appears on the system profile, the icon on the menu bar is completely gone)
All three issues happened at the same time, the night before everything was working perfectly fine.
If anyone could help... please!!!
Summary:
MacBook Pro Mid 2010 (http://support.apple.com/kb/SP583) Unibody, can't take out the battery.
Solutions tried:
- Reset SMC: Turning on while holding Shift + Ctrl + Option + Power Button (This makes my MacBook forget about the battery and start up with really loud fan noise, battery icon appears with an X on it, keyboard backlight buttons work, they show brightness level on screen, but the actual light won't work, no bluetooth, no isight)
-Reset PRAM and NVRAM: Turning on while holding Option + CMD + R + P (I have waited for 2 chimes, 3 chimes and 4 chimes at different times, nothing happens. Light, bluetooth and isight are still gone)
-Holding Power Button for 10 seconds, 20 seconds, longer... nothing changes.
-Creating and logging in as new admin user, nothing changes.
-Deleting the bluetooth.plist file and powering off and on again, also rebooting
-Deleting the SystemConfiguration folder, powering off and on again, also rebooting
-Installing "blueutil", didn't help at all, turned it off via terminal with command blueutil off.
-Performing Apple Hardware Test - Shows no erros or problems on any area after one full hour of testing (Performed the extended testing)
-Leaving it powered off overnight
Please anyone help meee!! I can't afford going crazy!
Thank you so much in advance!

****UPDATE***
Hi guys i got across this forum after searching for bluetooth, front camera and the most ANNOYING no lost keyboard backligth.
After run all the test, procedures, tweeks and, and everything i remenbered that once i sent my MBP to repair at you bring i break, turns out that the little ribbon flex connector coming from the mother board ( from the rigth to left) was loose since the adhesive wich they used shrink do temp changes, anyhow y popped out the glas and found the flex cable totally sticked to the glass pulling out of the pcb board connector, reinstalled it smoothly and that FIXED the camera, bluetooth and keyboard backlight!..
thats it. hope i helped some frustraded owner.

Screen backlight and keyboard backlight not working

Yesterday I turned on my old but proud PowerBook17" and the *screen was black*, but you could barely see everything. *Also keyboard backlight is not working.*
I read many many forums and all say that black screen caused by inverter failure, but in my case keyboard lighting is also dead, so I wonder *if this is something different* and not the inverter.
I would appreciate any advises or ideas cause I love this machine..
Thank you in advance!

Same problem here. I initially thought the auto-brightness problem had been fixed in 10.7.3, but sadly it hasn't. The auto-brightness works when the Mac starts, but I find it loses control and fails after wake from sleep.
I have telephoned AppleCare several times but they are not aware of this bug. They think a PRAM reset cures it, but it doesn't. As soon as the machine goes to sleep then auto-brightness fails on wake.
I have used the Apple Form to report the bug. It might eventually get fixed if others would kindly report it as well please. Here is the link:

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".

Macbook Pro 17inch late 2011 keyboard backlight not working

Recently near the end of sum me 2014 I only noticed the backlight keyboard not working at all. I have done the following to try and rectify;
1. Reset SMC
2. Rest NVRAM
3. Disconnected battery and the above
4. hardware test online, result showing no issues found.
with all outcomes proving nil. Pressing Fn + F5 or F6 does show the brightness either increasing or decreasing but with no light. I then opened her up and disconnected a cable that was to the LHS of the RAM boards but this only powers the White Sleep LED and not the backlight keyboard on this 17inch model. My next step is to remove the mother board and find the actual cable that does power the backlight LEDs and ensure that it is connected. Similarly around the same time I noticed this with the backlights the fans were running fast. However the weather has gotten cooler and the mbp is not running fans as it was when it was in the warmer months.
Do I have to remove the motherboard and actually make sure that the connector for the backlights hasn't been dislodged?
Anyone out there with a 17inch mbp late 2011 that has had this problem please help.

Thanks Ogelthorpe, I found an excellent video (not in english but it didnt matter) https://www.youtube.com/watch?v=8HNAGodYMNA .
What I found was that the keyboard backlight is intergrated into the black plastic cover that is between the motherboard and the back of the keys/LEDS and its all one piece back to the connector that connects to the motherboard under the LHS fan. I need more details to find out if the LEDS are controlled by a chip or what, but it seems to me that I need to visit an apple store/repairer, however this will be really difficult for me as Im in an isolated location. If there are further tests that I can conduct on my own, I would be grateful. Even if there are tests that Apple themselves conduct to find out what the problem is

Keyboard backlight not working like it used to

For some reason my keyboard will not let me manually adjust the back light.
I tried unselecting the "illuminate in low light" in settings- but that doesn't help. And when I go back into preferences it shows as being selected again. How do I override the backlight so that I have full manual control in all lighting conditions?

Install Lab Tick.

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!!!!

Screen not auto dimming correctly

I started to have an issue when the playbook auto dims the screen goes to a very light black/ dark greyish screen when i turn it back on the screen is really dark and the screen is not normal. I have to turn off the PB by pushing the power button then turning it back on to correct issue. anyone know how to fix this annoying issue?
I use my playbook for work all day long so i use word and excell

Try putting your thumb over the LED. If it does it then, it is the auto dim which can be turned off in settings.
It is designed to dim the screen when indoors or at night to reduce glare, but it is all or nothing and often dims at an inopportune time. Try it, it's. Settings, Screen.

Keyboard Backlight not responding at startup or after awakening.

The keyboard backlight on my MacBook Pro does not work upon startup or upon awakening. Even when I cover both of the speakers it fails to turn on. I have to press F10 and then it lights up but, it lights to the first bar. Not where I had it before it went to sleep. Is an body else having this problem?

Make sure the keyboard is set to automatically illuminate in the Keyboard & Mouse System Preference.

Toshiba Satellite S70-B - Keyboard backlight not working?

Hello, I purchased a brand new Toshiba Satellite S70-B laptop with Windows 8 on it. When I received it, I removed the harddrive and installed a SSD with Windows 7 on it. After getting help from Toshiba support, all the drivers and harware seem to work except the backlight keyboard? I spoken to several Toshiba support techs and finally came to the conclusion to send it in to change out the keyboard. Yet I fear if I send it in, they will remove my SSD and reinstall a hardrive with Windows 8 as their solution. Does anyone have other suggestions... ?? Any help is appreciated.

I am having problems with my keyboard backlight too. I spilled water on mine and had to totally take it apart, until then I never had any problem with the shortcut key turning it on and off. I found this last night. Unfortunately. it didn't work for me Also became disappointed when I searched and searched for that magic timer on my desktop he spoke of. Let me know. 1) Shut down laptop
2) Turn on and start tapping the F2 button until you get to the BIOS screen
3) Scroll over to power management and change the setting for your backlit keyboard from off to on.
4) Press F10 to save and continue to start up.
5) Enjoy.
Believe it or not, I JUST fixed this issue on my own a665D laptop. I am still tweaking it though because after this, the shortcut keys don't allow you to turn the backlight off so I'm typing on a keyboard who's LED's wont go off as of yet. But this should help for now.--REVISION: I am done "tweaking it" as I have found the answer and it was glaring me in the face. Instead of just turning it to the ON position through BIOS, turn it to TIMER. You can set the amount of time you want it to stay on when ever you press a key and the FN+Z shortcut works when this is set up so you can turn the keyboard on, off, or to follow the timer right from your desktop. I hope this helped.

You are officially awesome. Worked perfectly; I never would have ventured into the BIOS without an exact guide like you gave (Would have blown up the laptop or something lol). But anyway, thanks so much,

Keyboard backlighting not working when using Windows in Boot Camp

Hi, I'm posting this for a friend with a new Macbook Air. He says that his keyboard backlighting does not work when he is using it for Windows (don't know which, but probably Vista). Any ideas why? Thanks. Gary

Install all the drivers needed when running boot camp - try for example inserting a DVD - then press the eject key - See if it comes out - If it doesn't install all the drivers - try Control Panel - If not try re-installing your version of Windows.

GE70 2OE keyboard backlight not functional

Hello! I just recently bought a MSI GE70 2OE from Newegg. It was advertised as having a blue backlight.
However, after installing windows 7 and updating all the drivers using LiveUpdate, the keyboard will not light up.
The other function keys work fine, but when I press the Fn+- or Fn++ the keyboard does nothing. I also noticed some people mention that it would take them to the dragoon army website, but it has never done that for me. It simply does nothing.
I downloaded the windows 7 bios update for this laptop from the MSI site, and used the installer.
it popped up a CMD window and did some stuff then told me to restart. I did and no change
I also reset the ECM or whatever by shutting down by holding the power button till it shut off, removing the battery and power cord and letting it sit for an hour. overkill on the hour i know but i fell asleep waiting on it XD
anyways, ive searched and searched and can't find any other things to try.
ideas?
Thanks
Dusty

It seems MSI tech team is doing good service here.
Of course we customers will feel worry free once the trouble come to us.
Just come here and post the question, and we'll get satisfied!
