Keyboard lights won't work

so i have a mid-2009 macbook pro: 13-inch, 2.26Ghz.
it was running 2GBs of RAM until this afternoon when i upgraded it myself to 3GBs with a 2GB stick.
i followed the instructions from apple to the absolute letter. however now, my keyboard lights aren't working. but it's funny... usually in direct light, the Fn keys that control the keyboard lights won't allow you to adjust the light, right? but they will for me, except there's no light to adjust.
i couldn't have done something, right?! i mean... i was was super careful and only handled the ram section, after which i blew off some dust and sealed it up again.
please help!

sadly... no success
i followed the instructions exactly; restarting and all. no luck. i did hold the buttons though... is it supposed to be a hold, or a quick "hit"?
i saw your post about a better look, so i opened the back again and took a better picture.

you can see the connector just below. i tried, again, to make it go in. it fits, but i can't get it to stay. that must be the job of a professional. i can't do anymore now - i'm too involved, and i'm worried i may break more than just some stupid backlighting on my keyboard.
in other news: iphoto does open a lot faster now!
thanks again.

My keyboard lighting won't work. I can't turn the light up on the keyboard?

The keyboard light control (F6 key) won't work...someone help please?

The MacBook uses it's camera to detect the light level in a room and ajust the screen/keyboard brightness appropriately. If you are outside or in a well-lit place, your Mac will sense this and give you a circle and slash sort of symbol when you press F6 to tell you that you are unable to turn the keyboard lights on.
You can disable this feature by going into System Preferences>Keyboard>Uncheck Ajust Keyboard Brightness in Low Light.

Why keyboard light doesn't work after HDD replacement?

Hello,
I upgradet my MBP with Momentus TX 750 and now my keyboard light doens't work.
What can I do to fix it?
Best Regards

@kiki1871: This would be the last option I would take. I cloned the HDD before replacing it to avoid the whole OSX installation & backup procedure. I wonder if I could download the driver and install it now. Any hint wherefrom I can get it?

Hello Kian,
This may sound silly but if you put your hand over the isight camera, do the lights change on the keyboard?

Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If this does not help, you may have to take the MBP to the Apple Store to have it checked.

Sounds like it could be a hardware problem.
Try a restart or reset to see if that helps. If not, contact Apple Support.
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).
No data will be lost.

MacAIR keyboard light won't light up automatically

MacAIR keyboard light won't light up automatically, although I did tick where it says 'adjust keyboard light in low light' . It's OSX Yosemite 10.10

Good morning Otabek_USA,
If your MacBook Air's keyboard backlighting is not behaving as it should, I would suggest that you reset the computer's System Management Controller. Use the steps in this article -
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
Specifically -
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC
Thanks for using Apple Support Communities.
Best,
Brett L

Keyboard Lights won't turn ON

My keyboard lights suddenly won't turn on. I don't know what the problem is. I tried clicking on the F6 button which will turn the lights on, but this time it appears a NO sign when I clicked on it. Please advice.

Try resetting the NVRAM and SMC. Only reset the SMC if the resetting the NVRAM doesn't work

Zoom keyboard shortcut won't work with "Italian Pro" keyboard, Zoom keyboard shortcut won't work with "Italian Pro" keyboard

Hi everyone,
I am trying to get to the bottom of this mystery. "Italian Pro" is the keyboard I use almost all the time, and for some reason this zoom shortcut won't work. Another user assured me that "cmd-+" is the shortcut also in that keyboard. Mine doesn't work though. I have tried removing the keyboard and reapplying it. I've tried to use it on different browsers and different applications. I've even created another user and logged into that, installing the keyboard there. Nothing has worked, so can anyone suggest anything? What do I do next? (I know it doesn't seem like much but the issue really interferes with the flow of my things) Thank you!

Some other Zoom entirely?

If we're talking about (b) and (1), then this 'other user' (his initials wouldn't be TG, would it?) was right. My keyboard is US QWERTY, and, if I switch to Italian Pro, ⌘-+ works. However, as the 'other user' has already told you, to do ⌘-+ with the Italian Pro keylayout on the US QWERTY keyboard, you have to press simultaneously the keys labelled ⌘ and ] -- as you can easily see in Keyboard Viewer.

My keyboard chortcut won't work

I try to create a shortcut for a software that I frequently use, it won't work. I assigned "cmd + t " to it under keyboard shortcut of the keyboard and mouse. Even my roommate has this problem too. Is there anything I need to setup before customizing key short? It is very frustrating since this feature is one of the reason why I got my mac yesterday...

Welcome To  Discussions KelWong!
You could also just put the application in the Dock, for easy access to it.
Navigate to the folder where the application is. Probably the Applications folder.
Locate the application, and position the cursor on it.
Press the mouse down, and drag the application to the left side of the Seperator bar on the Dock.
When the icon appears in the Dock, release the pressure on the mouse.
When you want to load the application, just click on that shortcut.

Keyboard light doesn't work after updating to 10.8 on MBP

I have tried to update a MBP from Snow Leopard to Moutain Lion. But after updating the keyboard lights stopped working. Its A MBP from mid 2010 Core2, 2,4Ghz
We have tried to reset the smc.
Tried to untick the automatic brightness contoll of the keyboard llumination in system preferences.
Tried to use F5/F6 and it just shows that the keyboard light is turned on but its completly dark.
Is it coming a an mac os x 10.8 update for this problem?

Sounds like they did an Archive & Install, which leaves you with non-functioning Pro Apps (and Adobe apps, if you have any).
Try removing Final Cut Pro and Compressor and reinstall.
Instructions for reinstalling Final Cut Pro: http://support.apple.com/kb/TS1846
Instructions for reinstalling Compressor: http://support.apple.com/kb/TS1888
There is an application called FCS Remover, but I am not sure if it works with Final Cut Pro 4.
If it is still not working, I would try what David suggests.
Here is a list Jon Chappell has compiled about what versions of OS X, QuickTime and FCP works best together: http://www.digitalrebellion.com/blog/posts/recommendedquicktime_and_mac_os_configurations_for_final_cutpro.html
If you live close to an AppleStore you could try to bring it back and ask them to help you.
Best of luck!

Undo keyboard shortcut won't work

I have quite a bizaare problem - the keyboard shortcut for undo will work after I restart my computer, but after awhile, it simply stops working. I am thus forced to click on Edit->Undo every time I want to undo something. Once the shortcut stops working, it applies to all applications. I have not been able to identify any "trigger" which causes it to stop working. I've tried to "Restore defaults" in the Keyboard shortcuts tab under the Keyboards menu, but this didn't have any effect. Any ideas?

F7 and F8 Keyboard shortcuts won't work correctly.

I've just recently installed LR3.6 and it's my first experience with LR. I've been following Lynda.com tutorials and all of a sudden the F7 and F8 function keys won't work.
The F7 just does nothing and the F8 opens iTunes every time I press it. I've tried everthing I know (not being much of a Techie) without success. I installed one upgrade download since I installed the original CD software. Should I just delete the program and re-install the program? I believe the F-keys were woking originally. I'm sorry, but I was going thru the tutorials and not being as observant as I should. All I know for certain is that they do not work now.
I'm using an iMac 27 with the wireless keyboard. OSX 10.6.8.
Thanks for any help. - John, Vancouver, WA

X200 keyboard light no longer works in Win7

I just updated the BIOS to the newest one (released Sept 2010). I'm using Windows 7 Professional 64 bit. My keyboard light was working in Vista a week ago, but after installing windows 7, the light stopped working. Anybody know a fix?

boot into bios menu (press F1 during laptop startup), now press the Fn + PgUp to see whether the light works. If it doesn't then you have a hardware or bios firmware fault.
You could try reflashing the bios to an older version and see whether that fixes the issue.

My mac keyboard lights are not working

hi..
i m using mac pro 13... suddenly lights of my the keyboard is went off...i restart the machine by nothing happen.. the problem is still same only..plz help me out...
thanks,
jatin

What do you have in System Preferences, Keyboard under "Adjust keyboard brightness..."?
What happens when you push F6 to increase the keyboard light intensity?
Normally, if you have that checked, the keyboard lights only come on if the ambient light level is sufficiently low. They go out when the light level gets high enough. (Sorry if I am stating the obvious.) The sensor is at the top of the display, where the camera is. If you cover the camera lens, do the lights come on? (You may have to turn up the light intensity with F6.)
Try unchecking that preference box.
If nothing else works, try resetting the NVRAM.
If that doesn't work, you probably will have to take your machine in for servicing.
