Volume and brightness keys not working with new keyboard on imac

I just purchased a new wired keyboard for imac and brightness and volume control keys not working . i have tried adjusting keyboard settings. I have software version 10.5.8. Do I need to upgrade software. Thank you for any help.

Do you have "Automatically Adjust Brightness" check box ticked in System Preferences > Displays > Display ? If so, you can't manually adjust brightness.

StarTech Adapter not working with Dell Inspiron 15, model 3521

Side Note: I wrote a reply to a thread that was from 2013. I do apologize because the link was sent to me by my bf and I did not realize how old it was. Since my reply has to be approved I can't delete it.
Current Issue: StarTech Adapter not working with Dell Inspiron 15 model 3521
I bought my Dell laptop last year and at first I did not realize that it had only one audio jack (combo, as the specifications manual says), I only noticed when I was trying to plug in my Ozone Rage ST headset.
I searched online threads and found out that I needed an adapter and most people mentioned Headset Buddy. I couldn't find any adapters for sale in my country (or employees didn't really know what I was talking about) and since Headset Buddy is a bit expensive, I decided to try StarTech Headset adapter for headsets with separate headphone/microphone plugs - 3.5mm 4 position to 2x 3 position 3.5mm M/F www.amazon.com/.../ref=cm_cr_pr_product_top.
It arrived today and let me tell you that I can't make it work. I can hear everything but I can't get the external mic to work or even be detected. I have always used my headset (mostly for gaming) and I prefer to use my external mic rather than the internal one. First I connected my headphone and mic jacks to the adapter and only after that did I connect it to the laptop combo jack. I also tried vice-versa. It didn't work, regardless of the order. I even tried with a different headset and it still didn't work. What else can I do?
I have also found a thread on Dell forums saying that Headset Buddy doesn't even work on Dell Inspiron 15, model 3521. So since it doesn't work and I'm assuming StarTech doesn't, either, what am I to do/buy?! I am getting extremely frustrated and I'm very disappointed with Dell because the brand should have included with the laptop a proper working adapter for these situations and not make its customers buy an extra accessory to make whatever working gear they already had function. It just doesn't make sense to me! Either make the changes work properly or simply don't touch anything. I spent some of my savings on this laptop which, overall, is great but now I am being forced to spend more on an item to allow me to use my headset. I am running out of options here and even Dell can't seem to tell its customers with 100% certainty what really works for this specific model.
If I can't make the adapter work, I just hope I can return it, otherwise I'll end up with no refund and with a piece of equipment I have no other use for!
Any thoughts?

Hi,
Thanks for your reply.
This is the first time I was forced to buy adapters such as these so I don't know if I'm doing something wrong or if there's anything else I can do to make it work. When I plug the adapter to my Dell, the laptop presents me with several options such as: headphones, headphone, speakers, skull candy headphones, etc (maybe some may have different names but since I see them in Portuguese, I'm not quite sure how they appear for someone who has the computer in English), I have picked different options and it still doesn't work, the only noticeable changes are sound quality related, I guess.

Using shift key not working with bluetooth keyboard

Am I missing something here? Or does the shift key not work with the iphone using a bluetooth keyboard? I'm using the logitech K810 for reference on iphone 6 iOS 8.1

The shift key works just fine on my Bluetooth keyboard. So I would imagine this is an issue with your keyboard.

Brightness and volume control keys not working with windows 7?

brightness, volume control and some other keys keys are not working with windows 7 with macbook pro retina. Can I fix it?

Welcome to the Apple Support Communities
Have you installed Boot Camp drivers? You need them to make your computer work properly on Windows, and to use your function keys as Play or Pause, volume and brightness keys.
To install them, follow these steps:
1. Press the X key while your Mac is starting to start into OS X.
2. Open Boot Camp Assistant and tick only the option to download Windows support software.
3. Windows support software will be downloaded and Boot Camp Assistant will ask you to burn it into a DVD or USB drive, so do it.
4. Start into Windows, insert the DVD or USB drive and install Boot Camp drivers. Your Mac and your volume and brightness keys will be working after installing the drivers

Right shift key not working with middle row of letters

The right shift key on my Macbook Pro does not work with the middle row of letters. It works with all other letters and numbers, just not A-L. Nothing out of the ordinary happened, it just stopped capitalizing

Try resetting your SMC and PRAM.
Resetting the System Management Controller >>
If that does not work, test it using an external keyboard.

Keyboard: audio and Brightness control keys not working with or without fn

The Keys for controling Audio and Brightness (F1-F5) do not work.
Also combined with pressing the "fn" key the keys do not work.
So i only control audio with the remote control or the slider in the menubar.
Making a reboot with deleting pram didn't help.
I'm running the up to date version of leopard on a macbook pro (core2duo).
I also searched in the forum for this problem.
I oten read about "sytem control"-"keyboard and mouse"-"keyboard" and the F1, F2, etc. to use as...
but switching this button on or off doesn't change anything.

problem solved:
the couse was the software update 1.1 for macbook pro, because there i had the problem like in this thread: http://discussions.apple.com/thread.jspa?messageID=6142512&#6142512
and did the solution like that, but there i maybe made some mistakes with renaming and copying, so i rinstalled the update and renamed it a copied to plugins, and now all works as it should.
thanks for help

Yoga 2 13 brightness keys not working - it was TeamViewer monitor driver

Hello, I have two Yoga 2 13's - I think both the 59403750 model. Both have the same specs.
In one of those Yogas the brightness keys - "F11" and "F12" - do not work and it is full 100% brighness all the time. In the other (good) Yoga they seem to work OK - at least I can get the brighness down a few notches.
When I press and hold the Fn key to get F11 or F12 to work the *seem* to do what F11 or F12 would do normally - e.g. in a word processor or browser. So it seems maybe just the brighness function of those keys are not working.
Lenovo has calimed that this is not a hardware problem and they are not responsibile for it under warranty.
I have done a little reading some time ago and seen something similar that was maybe fixed by installing updated video drivers. Well, that did not work - as of a couple months ago. At the time I also updated the BIOS - again no luck.
Any ideas /inputs you might have are appreciated. Thank you.
Solved!

scf /scannow 'found corrupt files but was unable to fix some of them. Details are included in the CBS.Log' and then something about 'not normally suppoorted in offline servicing'.
I'm reading from MS Use the System File Checker tool to repair missing or corrupted system files and in the mean time I'm also doing a chkdsk /r just to make sure that's not an issue before I start trying to repair any files. Both were refirbs (still under warranty) - so who knows about the HDDs. Luckilly I may have the other one to pull files from if necessary - if it is something that easy.
It's been doing this since pretty much the day I got it. I've never seen it work right on this one.
I appreciate the tip to factory restore but that is always the last option IMHO. That's a lot of time for me to get this thing back the way I want it. There has to be a fix for this silliness - I'll keep working on it and write back when I know more. Thank you very much for the help. If you think of anything else let me know.

Shift key not working with some keys

I am using a MAC Pro with two hard drives. One runs Leopard and the other MS windows. while in windows, the birghtness key illuminated (f2 key) and suddenly the shift 2, w, s, x keys quit working. I decided to reboot and while holding the option key to boot into windows, the system did not recognize the option key and booted me into Leopard. so now I notice the shift 2, w, s, x, and option key are not working. Any suggestions? Also, the brightness icon is still lit up on my screen and I am not able to make it go away or even adjust...

I'm having this same exact issue. Anyone know of a fix? Is it possible junk in the keyboard?
I tested my keys using the keyboard viewer, and when I hit function it recognizes it, but it doesn't when it is loading.

Eject key not working with MBA Superdrive

For MBA owners with MBA Superdrive, could you please let me know if the Eject key is working? I just bought a MBA Superdrive but the Eject key on the keyboard is not ejecting disc. When i press the Eject key, i don't see the gray Eject icon on the screen, unlike all other function keys (for example, volume control, keyboard backlight control and screen brightness control). I can ctrl-click (or right-click) on the disc and select "Eject" to eject disc. If i do a ctrl-Eject, i can get the "Are you sure you want to shut down your computer now" window to show up so the Eject key does not appear to have any physical or electrical issue. I can also boot into Boot Camp (Windows 7) and the Eject key works perfectly.
I have installed and uninstalled Virtual Box and Parallels so i am not sure if my problem is related to that.
Apple's tech support recommendation is to do an archive install, which in theory will keep all my personal data but create a new Systems folder. But i would like to try something less drastic before going that route.

Thanks. I not only did an "archive install" of Snow Leopard, i also did a erase install. But the Eject key is still not working like it's supposed to. I think i am going to try clearing the PRAM next.

Brightness keys not working anymore and screen frequently flashing black and staying black!

I had my macbook pro in for repair twice last month. They replaced the logic board and had to take the screen off and look at it due to there being a potential crack. Now, when i got the macbook back the first time, after replacing the logic board, everything was fine, the brightness keys did not work at first but a restart fixed the problem. 5 days later i had it back in so they could look at the screen because i thought there was a crack on it, which turned out just to be some debris on the inside! Still had to pay a 50 quid inspection charge!
ever since the macbook has returned from this the brightness keys have had a delayed response in that, when i increase or decrease the brightness it took about 10 seconds for the screen to actually change. This happened everytime.
A few days ago for no reason, the screen started to occasianally flash black. It wasnt a problem at first, but sometimes it flashes back and stays black so i have to restart my computer. Sometimes when returning from sleep it stays black as well. On top of this, the brightness keys have completely stopped working all together now.
My laptop is not in warrenty anymore, it ran out after i got it back the second time. I was too busy with work and i needed to use the laptop so i couldnt really sort anything out.
Is there any policy saying that if the laptop comes back from repair and has new problems not caused by the customer, but by the repairer, then they will fix it free of charge?
Many thanks

nobody can help??

Wireless Keyboard Brightness Keys Not Working

Hello.
Since an update a while back the brightness adjustment keys for screen brightness on my apple keyboard have stopped working. These are the F1 and F2 keys normally.
On my Macbook Pro keyboard they work fine but the wireless keyboard keys do not.
Anyone having the same issue or know a fix?

I had the same problem, minor but annoying. I found the cause, It is a combination of factors. If the following are true:
• You're using a laptop
• You are running 10.6.x (not sure which revision, true of 10.6.6)
• You have an external display connected
• The external display is non-Apple, or you don't have a USB connection to an Apple display
• You are using an Apple Wireless bluetooth keyboard
• You have the menu bar *on the external display*
Then the brightness keys won't adjust the brightness of the laptop's display.
The apparent logic is that if your main (menu bar) display is external, and you're using an external keyboard, then you must want the brightness keys to control the external display. The bug in the logic is that it doesn't check to see if the external display is capable of brightness control. So, it appears that the brightness keys don't work at all. Note that Max OS X can only adjust the brightness of an internal display or an external Apple display with a USB connection.

Apple wired keyboard - certain keys not working with shift

I treated myself to a new Apple wired keyboard MB110B/A for my mac mini.
My previous keyboard worked fine, however the new keyboard causes the computer to enter the Hardware Test mode every time the computer is restarted. The computer only starts normally without the keyboard connected (or with my old keyboard connected).
Once the computer has started, if I plug the new keyboard in, it appears to work normally with the following exceptions. The following keys do not register when the "shift" key is pressed: 2, w, s, x. This fault does not occur with my old keyboard.
As these keys are in a line, I think there may be a wiring fault inside the keyboard. If so, would this explain the computer entering Hardware Test mode every time it is started with the keyboard connected?
Thanks in advance.

Definitely sounds like a hardware fault in the keyboard to me. I assume it's the same whichever USB port it's connected to? (and if you plug it into another Mac, too)?
Of course, as that keyboard is glued together in final assembly, it's completely unrepairable.
If it's a reproducible fault (and new anyway): take/send it back for replacement. You shouldn't have any trouble with Apple arguing.
