Software :: Keyboard Backlight Sensor Not Working?

Jun 14, 2010

My Macbook Pro keyboard Backlight is not working properly even in a darkroom.

I need to install a third party software (Lab Tick) to switch on the keyboard light.

I am not able to use F5 and F6 key to adjust the light dimness. I suspect the light sensor is having problem.

However, last night I received an error message, saying that my Mac is having problem, I need to press the Power button to restart the Mac.

After restart, the keyboard backlight is working (without Lab Tick), and I can adjust the light with F5 and F6.

But now,after I made the Macbook sleep and wake up, it's back to abnormal again.

Hardware :: Keyboard Backlight Not Working?

Feb 19, 2009

I own a MacBook Pro 5.1 (late 2008) and since a couple of hours my keyboard backlight suddenly turned off and I can't reactivate it anymore. When pressing the corresponding buttons which regulate the intensity of the backlight I get only the backlight icon on screen with a not available button attached to the lower corner. Is anyone familiar with this problem by chance? This happens under both OS X as well as Windows XP.

Aug 18, 2009

The backlight for the keyboard on my powerbook G4 isn't working. It worked perfectly a few weeks ago. Now when it is completely dark in the room and I turn the backlight all the way up the keys dont light up. Do the backlights on these keyboards really break?

MacBook Pro :: Keyboard Backlight Not Working After Disassembling

Apr 18, 2012

After a little spill of coke, my keyboard becomes sticky. I bought new one from ebay and replaced it. Everything works fine except keyboard backlit. I tried basic solutions such as  SMC reset, check cabling again but not worked.

MacBook Pro :: Keyboard Backlight Not Working After Small Spill

Aug 6, 2010

I was drinking some tea and bumped into the table the mug was sitting on. A couple of drops splashed out and got on my unibody macbook pro's keyboard. I quickly wiped it off and turned off the computer. I let it sit for a while, but I didn't think anything of it because it was only a few drops. I turned it on and it was fine, however the keyboard's backlight is dim on the right side of the keyboard.

MacBook Pro :: Keyboard Backlight Not Working - OS X Mountain Lion (10.8.5)

Dec 9, 2014

Well, after my keyboard backlight going out, and me looking for multiple solutions, I've found multiple solutions on the internet that include deleting the file from the Library file. My issue is, I'm actually missing this file from my Macbook pro, which leads me to believe that this is the main reason that my backlight isn't working. Is there anywhere I can find this file, or any reason why I'm missing this?

Just to add in, I have a corrupt Hard Drive, and plan on fixing it soon. Could that have anything to do with it?

MacBook Pro :: LCD Not Working Backlight Working And External Work?

Apr 11, 2010

I have tried a few thinsgs to try and get it to work including reseating the cables and that has not helped. As the title says, the back light works as i can see the screen getting blacker/greyer. Also the external output works as well. I'm not sure what to do at this point because I can't find information on an inverter board for the LCD, only the LED backlight think this could be an issue with the video card 8600M or is my LCD dead and I need a new one?

On a side note I have taken very good care of this computer, no drops, making sure the HDD is parked before moving, having it in a protective case, etc. The only difference is that I gave this to my sister to use and after a few days it died. (seems everything she gets that's electronic dies these days, meaning I probably shouldn't give her anything that has a circuit board in it....)

MacBook Pro :: Light Sensor Turns Up Brightness Of The Backlit Keyboard

Apr 29, 2010

So I've recently purchased the new 13" MBP, and to my understanding, there is a light sensor that turns up the brightness of the backlit keyboard and screen when in dark environments.

However, the problem with my MBP is that when I turn on the lights in my room, the screen brightness and backlit keyboard both turn brighter, and when I turn off the lights, the screen and keyboard grow dimmer, which is exactly the opposite of what is supposed to happen.

PowerPC :: Way To See That Temperature Sensor Is Working?

Jul 9, 2010

I could just by the replacement fan and swap it out but I am wondering if there is anything else that could be malfunctioning and causing the fan to NOT spin up - anything I can check before forking out the cash.Is there a way to see if the temp sensor is working? Could it be the LB? Can I test the electrical supply to the fan by using a multimeter? If so what setting/voltage, etc should I use to read that? And lastly, is there more than one fan?

MacBook Pro :: Sudden Motion Sensor Not Working?

Sep 19, 2010

I just dropped in a 1 TB drive into my 17" MacBook Pro and it seems like that the Sudden Motion Sensor doesn't work not. I do not hear the sound when it engages as I did with the stock 500 gig drive that was in there. My understanding is that the Sudden Motion Sensor was not built into the drive and it was built into the notebook itself. Shouldn't I still be hearing the drive stop when the Sudden Motion Sensor engages?

MacBook Pro :: Ambient Light Sensor Not Working?

May 16, 2010

As of today, I noticed my ambient light sensor doesnt seem to work. I tried disabling and re-enabling it in system preferences, but that hasn't done the trick.

Is there some test I can do to see if it's working or not? I know it worked two days ago, because i took the i7 15" MBP outside and it automatically switched to max brightness. Today I took it outside and the brightness didn't switch at all and I couldn't see the screen it was so dark.

Since the last time it definitely worked, all I've done is install Windows 7 64-bit with Boot Camp and hooked up the MBP to an external 20" monitor with a minidisplay-DVI adapter.

MacBook Pro :: Brightness Sensor Not Working Properly

Jun 14, 2010

I bought my first Mac computer last month, the 13" 2.4 variant. Loving it so far.I have lately noticed however that my ambient light sensor is not much of help. Before, after coming out of sleep I could notice the screen changing to accommodate for the room's light output. I could also put my hand over the sensor near the iSight and witness the brightness decrease in front of me.

Hardware :: How To Turn Keyboard Backlight Off?

Jul 2, 2009

I just got one of the aluminum MB Pros and had to install Windows XP on it.

What I find annyoing is that I can't turn the keyboard backlight off: The F8-key (as suggested by Apple's support) nor the way it works under Mac OS (dimming completely by pushing F5, turinung it off with the next key press) do the trick for me.

OS X :: Keyboard Backlight Battery Consumption

Mar 30, 2010

Two quick questions:
- Is it bad to have the keyboard backlight always on? Will it somehow burn out the little lights?
- How much less battery power will I lose if I have the backlight always on? (I use Labtick).

MacBook Pro :: Any Way To Turn On / Off Keyboard Backlight

May 30, 2010

In regards to a 2010 13" macbook pro's illuminated keyboard.

1.) Is there a way you can make the keyboard's backlight become brighter in low light situations?
2.) Is there a way for the backlit keyboard to turn off in lit rooms and turn on in dark rooms?

For some reason the backlit keyboard becomes dimmer in low light situations. I'm finding it really irritating. I have a feeling this is the way it is suppose to be so that the keyboard doesn't blind you. Any programs to hack the light sensor?

MacBook Pro :: Keyboard Backlight Will Not Turn On?

Apr 5, 2012

I was surfing the web when my keyboard backlight started to fade on and offat somewhat regular intervals. After about a mintue or two of this, the backlight just went off all together. Now, when I press the F5 or F6 key to brighten or dim the keyboard, the keyboard backlight does not respond. The usual screen pop-up that shows how bright or dim the keys are no longer increases or decreases but shows the symbol of O with a slash through (like the no smoking symbol).

MacBook :: OS X Mavericks (10.9.1) Sleep Sensor Isn't Working Properly

Sep 4, 2014

Just this morning, I opened my MacBook which had been sleeping overnight. for some strange reason, even when the screen was up, the light at the button was still glowing (indicating it was asleep). I tried forcing it to shutdown. When I turned it on again, it went to sleep mode right when the desktop was about to load. I tried booting from Windows 7 but sure enough, when I reached the login screen, the computer went to sleep. I concluded that it was definitely a sleep sensor problem.

MacBook Pro :: Unable To Work With Keyboard Backlight

Dec 9, 2010

My keyboard backlight isn't working... whenever I try to turn it up it gives a circle with a line through it. I have read that there is an ambient light sensor that turns off the keyboard backlight when it is too bright, however that has NEVER happened before and I have used it in direct sunlight and the backlight still obviously works. It's not even bright right now but it won't work. This is very frustrating, there should be no sensor that turns it off it should be the brightness I tell it to be.
