MacBook Air :: Function Keys Not Working For Brightness Or Volume?

Mar 21, 2012

I have a 2011 (?) macbook air and ever since my trip to the genius bar for a battery issue my function keys don't work after I wake it up (just opening screen).  May also be related to last firmware update?   

I have checked the function key mapping in settings and they are normal.  The volume key launches Expose and the brightness keys (and others) don't do anything.  A reboot helps but only untill the first time I put it to sleep (close/open lid). 

MacBook Air, Mac OS X (10.7.3)

MacBook Air :: 2011 - Brightness / Volume Keys Not Working

Aug 21, 2014

Really stumped by this. Recently (I think it was after a MacOS update but I'm not sure) my brightness and volume keys stopped working on my 2011 13" MacBook Air running MacOS 10.9.4. The F keys still work i.e. if I press Fn-F10, I get the expected effect from pressing F10, but if I just press F10, volume remains unchanged (should get muted). Mission Control, Launchpad, and media keys (rewind, play/pause, ff) all work. 

Using Karabiner, I checked to make sure the keys generate correct events. They do. Pressing the brightness keys generates 0x3 and 0x2. Pressing the volume keys generates 0x7, 0x1, and 0x0, which are the expected key codes defined in ev_keymap.h, the header file for HID. I can also adjust volume and brightness using the sliders in the appropriate section of "System Preferences." 

So volume and brightness itself can be changed. They keyboard keys themselves work and produce correct keycodes. But whatever operating system feature (HID?) that is supposed to read the keyboard input and translate it into commands to the display and sound drivers doesn't work. 

I've tried all the obvious stuff (restart, safe mode, toggle the Function key option in System Preferences->Keyboard). I've reset SMC and PRAM. Nothing has worked so far.  

The only other thing I can think of is that a while back (before this problem started occuring) I got annoyed by the power button in the top-right corner of the keyboard, which I would occasionally hit accidentally. I searched for a way to disable it, and I think I found something -- now it only does something if it's held for 2 seconds. A quick up-down strike does not do anything. Perhaps in tweaking some setting to achieve this behavior (I don't remember what I did), I screwed up something with the brightness/volume keys, but this screw up only became evident later.

OS X :: Volume Opens The Window For Expose And Does Not Control Volume Monitor Brightness?

Mar 9, 2010

Recently, my newer (last year) iMac probably running 10.5 started speaking and wont shut up... there is no obvious way to turn it off. I usually figure problems out myself but there are no system preferences that effect it. I even changed the voice in preferences as a test and it is still the same guy reading everything clicked in all applications except when I am in system preferences so far. Usually when I run into a dead end like this there is some mystery key command that works... anyone know?I also noticed that some of the top line (f) keys are not doing what they are supposed to any longer as well... volume up opens the window for expose & spaces it looks like and does not control the volume monitor brightness controls are not working either... I went to the key and mouse preferences and set the key strokes to default and still the same.

MacBook Pro :: Brightness Keys Have Stopped Working?

Sep 12, 2009

I have a MBP with an apple wireless keyboard. The keyboard has brightness keys on it but they have recently stopped working. It is strange as the keys on the MBP still work but the ones on the bluetooth keyboard, placed exactly in the same spot (the wireless KB and the Macbook pro's KB are exactly the same), don't.

MacBook :: Brightness Changes Rejected Using Function Keys

Aug 21, 2010

When I wake my Mac up from sleep, and attempt to change the brightness using the function keys, I see the brightness "image" pop-up on the screen, but when I try to lower it, the brightness doesn't change. The boxes quickly go down, but instantly go right back up to the original brightness. Running Mac OS X 10.6.4

MacBook Pro :: Volume And Brightness Buttons Out Of Work

Dec 26, 2010

I'm a noob to the MBP. Just got it last month and still learning how to use it. Anyways, my volume and brightness button worked a few hours ago, now it doesn't work. When I tried lowering the volume it doesn't work. Then I tried using the play button to start my itunes and that doesn't work either. I don't know what I did wrong. How can I get it back?

MacBook Pro :: Volume And Brightness Control Disappeared?

Apr 9, 2007

It seems that the control keys for brightness (default F1 & F2 keys) and volume (default F3, F4 and F5 keys) have moved to another key combination. Don't ask me what I've done . I already tried Fn, but that did not help.

Does any know how to rearrange the keys to the default keys?

MacBook Air :: Manually Controlling Keyboard Brightness With Function Keys

Feb 4, 2008

A few minutes ago I noticed that my MBA's keyboard was not lighting up as it's supposed to. A little experimenting and I found the solution (you may kick yourself, this is so simple):
The F5 key decreases keyboard brightness.
The F6 key increases keyboard brightness.
The icons on these two keys are the clue.

MacBook Air :: Volume And Other Function Keys Not Working As They Used To

Jun 21, 2014

The volume and other function keys aren't working as they used to. The brightness key doesn't do anything and the volume key isn't working either. I've tried to fix it on system preferences but it didn't work. They're not set to be used like normal function keys. I don't know what is happening they were working fine.

MacBook :: Volume Keys On My System Are Acting Weird?

Jan 17, 2009

When you want to raise or lower the volume, as you raise or lower them, the accompanying volume that you're setting it to should raise and lower as you go along. Well, I've noticed that this hasn't been happening lately and some of my other sounds have disappeared too, such as in ichat, the sent message and received message sounds aren't occurring even though the settings are set for them to happen. Anyone else experienced this before? I just want to know how I can get my volume keys to work again so that I can hear them as I raise and lower the volume even if there's no sound coming

OS X :: Gradually Increase/decrease Brightness With The Keyboard Keys?

Dec 11, 2009

I have a 15 inch aluminum macbook pro, Snow Leopard and recent updates all installed, but i noticed something on my friends 13 inch macbook pro that mine doesn't do.

On my friends, when you press the screen dim/bright button (F1, F2), its a gradual transistion, but on mine it just jumps down a notch.

For example, when you hold down the dim button on my friends MBP, it the screen dims in a similar way as to when you put your finger over the iSight camera, it fades to a dimmer screen.

Software :: Brightness Slider And Function Keys Not Working

Apr 30, 2005

The issue is with the brightness keys and the brightness slider controls. It appears that after the 10.4 upgrade the main LCD on some PBs and iBooks stops working. In my case the attached screen lost the ability to adjust brightness, but my external 20" LCD is fine. It looks like two things have happened. The association between the keys (F1 and F2) and the code for controlling brightness somehow got disconnected and/or the "capability" of the mac to adjust the brightness of the attached LCD got lost in the upgrade. We've tried repair permissions, rebooting, new users to no avail.

PowerPC :: IBook G4 - Volume And Brightness Stopped Working?

Aug 13, 2009

Up until recently, F1 - F5 have been Brightness and Volume controls, as they have been since I got the thing. I go to use the Volume, and it doesn't work. I then try the Brightness, and it doesn't work. F6 - F12 all work just fine, which leads me to believe that iBook had a brain fart.

My volume balance has always altered itself. Balancing itself out of one speaker left or right as it so chooses. I know it's smart, but now it's just screwing with me. Settings go and change on their own, dock icons have switched, but this one has stumped me. How do I get those hardware function keys back to doing what they're there to do?

Also, I tried it with an App called Rowmote, that lets you control your Mac from your iPhone, with Apple Remote-like control, and the volume won't change using that either. Another symptom is that sometimes it makes clicking sounds, as if it were changing slowly and glitchy (which it did click sometimes anyhow) when using the Volume slider in the menu bar.

No, the options in System Preferences is not checked to use them as FN. Any ideas?

Power Mac :: Assign Brightness To Function Keys On New Apple Keyboard In 10.3.9 Using Spark V2.1.1?

Mar 19, 2012

Following on from my recent post regarding the new apple wired keyboard after very helpful feedback from people who responded to my post I decided to take the leap and purchase it!  Good news is that I am really happy with it and am glad that I got it!  Much nicer then old apple keyboard that I was using.   

I also downloaded spark v. 2.1.1 which has enabled me to change the functions of Fkeys to enable to play, pause, etc... in itunes in accordance with the keyboard layout. However, there are two functions that I am having difficulty assigning which are the F1 and F2 keys which allow the decrease and increase of screen brightness. So that I can control my screen brightness using these keys.

OS X :: Mapping Other Keys To Volume

Mar 6, 2009

I just got a non-Apple keyboard, the Unicomp 104, and I absolutely love this beast. They even printed me custom "command" and "option" keys when I asked them to. The only thing I miss is that there are no volume control keys. Now, I found this link with a little hack to make an Applescript to change the volume: [URL]

This is much better than nothing, however I wonder if anyone knows how to map the vol+, vol-, and mute keys to other keys on the keyboard. I'd rather have that, because that way gives me the white volume box, and has the popping sound to give me an idea of the volume level, and can be modified with option for more incremental control, etc.

OS X :: Using Top Keys For Volume Control

Jun 22, 2010

I found a way to control the volume through the system preferences, but I tried to do this with the top keys that have the volume labels on them, but when I press one of them to lower or increase the volume, it either brings a widget up to the screen or moves the current windows off to the side, & does nothing to the volume.

OS X :: Is It Possible To Remap The Volume Function Keys

Nov 9, 2007

How would i go about remapping the volume function keys on my old white apple keyboard to match the sequence order of the macbook's volume keys?

what i mean is how can i remap the volume keys above the numpad so they are used in this order: mute, volume down, volume up like on the macbooks for F17, F18, F19 respectively instead of volume down, volume up, mute like on the old white apple keyboards for F17, F18, F19 respectively. if it is possible i would then just switch the volume keycaps around to match the mapping.

i found this article about modifying the to change the expos� and dashboard keys link. it says near the bottom that it may be possible to remap the volume keys but the author did not know the values... damn so close! does anyone know the values for the volume keys or know of any other way to change them?
