Auto brightness of screen and keyboard backlight not working

Basically, since I updated to OS X Lion, the auto brightness feature for the screen and keyboard hasnt been working, despite the fact I have it turned on
Thanks in advance for your help

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:

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!

Auto-Brightness on iPad mini Retina is not working properly.

Hello! Noticed that the Auto-Brightness on iPad mini Retina is not working properly.
It works correctly only when such a dark place, then unlock the iPad brightness will be at a minimum. Likewise, if unlock iPad in a room with light, the brightness will adjust to the surrounding space.
If I turn light into a dark room, the brightness slider does not move, and stands on the site. Checked on the iPhone 5S, there problems are not present. Auto Brightness is working correctly.
P.S. Sorry for my bad english!

iPad audio output does not work, except for on Siri. The mute button is not on, and the volume buttons have no effect/ don't work (unless Siri is open). I have reset the iPad, tried iOS7 and iOS8 resets, which didn't help.
iOS 8 isn't even out yet. If you are running iOS 8, I assume you are a developer and if you are, you are in the wrong forum to try to get help. If you are not a developer and you're running iOS 8, maybe that's why you are having problems on the iPad.
The audio output mostly works when headphones are out in, but has a tendency to cut out from time to time. Without headphones, Audio might start working again briefly from time to time, but most the time it doesn't. Any ideas on what is wrong with it and how to fix it?
The type that I made bold doesn't make sense. Is this a typo and you mean that " headphones are not in"?
I did take it to an Apple Store, but the inncorrectly insisted that my speaker was bust and it would cost £250 to replace the whole iPad!
And you know they are incorrect because you get sound here and there from time to time? That fact doesn't prove that something isn't working correctly inside. You could very well have a bad connection inside the device causing this, but somehow you seem to know that's not the case.

You cannot download the upgrade to Snow Leopard.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)

         7. Xserve (Early 2009)
     Are my applications compatible?

Touchsmart 520-1047c Mouse and Keyboard will not work after sleep mode

I have an issue which I need some help with. When my computer goes to sleep the wireless mouse and keyboard will not work unless I restart, however each one will wake the system up but will not operate after that. I have tried just making the display go to sleep, both go to sleep but that makes no difference same issue occurs. The only work around I have found is going into the power settings and turning the sleep mode off for booth the computer and display. This does not solve the problem it just masks it. New batteries, unplugged and replugged the dongle, updated the bios and all drivers. Don't know what else to try. Anybody know how to fix this? Thank you in advance for your help.

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".

MAC Mouse and Keyboard Do Not Work, when I am trying to re-install the OS using "Command R" option

I am trying to re-install MAC OS 10.8.2, but when I hold "command R" I am asked for the firmware password, but the keyboard and mouse do not work.
If I only select "option" during the boot up process it will ask me for the firmware password, keyboard and mouse work, but I can only select the HD option.
Can someone advise what is the problem here, and your resolution.
I have tried different commands "option + command + R' with no luck.

I tried what was provided on the link, but it is not working.
I hold it down, before the gray screen and the chime, but it only prompts but the firmware password.
I tried based on the specific order in the support document and at a random press and hold.
No go any other thoughts?

Keyboard Backlight not working anymore.....please help.

After installing Boot Camp 2.1, I can't get the keyboard backlight to work anymore. I am in the darkest of dark rooms. Pressing F8 just shows an attempt to turn it on but it has a circle with a line through it.
I am running Windows Vista 32-bit SP1.
Are there drivers I can install manually?
Thanks.

Here is something funny. I rebooted with the room completely dark. When Windows came back, the keyboard was backlit. But, when I turned the lights on, the keyboard stayed backlit. And, even better (or worse), when I rebooted again, the keyboard just stayed backlit even to the point where I was choosing between booting into OS X or Windows. That is crazy! I don't know what is going on anymore.

I have a new mac book pro (sept 2014) and am suddenly stuck on the log-in screen. Keyboard input is not working to enter my password. Seems to be a log in issue as keyboard works for forced troubleshooting. (And b/c when I first noticed the problem, I was able to enter my log in password but then everything sort of froze. Now, no ability to enter the password.) Already tried a basic restart and a cmmnd/ cntrl/ pwr troubleshoot to no effect.

HT1338 How can I conserve battery life on my new macbook pro? I got it 2 weeks ago and am noticing that the battery depletes quickly. I dim the screen and keyboard backlight & mainly use Safari (multiple tabs).

Appreciate any help!

     My daughter also just bought a Mac Book Pro 13" with the same issue. When we migrated over from the old computer, we brought over only her documents, no applications, and she was getting only about a 2 hour battery life on the new MBP. Somewhere in the MBP threads in this forum someone who was experiencing this same battery life problem said he was told by an Apple Genius in a retail store to try setting up a second user, and then to try working out of that user only. So we set up the second user, logged out of the old user, and the battery life readout is now about six hours after a charge when my daughter is logged in as the new user. If she needs old documents or other files she can always log in as the old user to use them, but she rarely has to go back. Whenever she is logged on as the old user the battery life shows under two hours, but when she she logs out and logs back in as the new user it jumps back up to around six hours.
     There seems to be no need to eliminate the files etc. that reside under the old user. As long as my daughter is logged out as the old user and logged in as the new user, the battery life is much better. Weird solution, but it seems to be working. She is running Lion 10.7.4.
     Hope this helps.

Keyboard Backlight not working after SMC reset

I have a Late 2009 MacBook Pro, and I noticed that the backlight for my keyboard stopped working last night. I Performed an SMC reset and powered the computer back up. Again the backlight never came on, but I noticed that if I pressed the keyboard brightness buttons the icon that used to show on the screen showing what the brightness is at, (like the volume one), was not showing up anymore. I checked the keyboard settings and noticed that the auto brightness for the keyboard dissapeard. Anyone have any suggestions?

try to reinstall your firmware, im having the similar problems, but reinstalling wont let me.... http://support.apple.com/kb/HT1237
