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).
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.
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.
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.
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.
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
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.
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.
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 com.apple.symbolichotkeys.plist 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?
I have a new 15.4 2.53. I have a question, by default. When you press the key 2nd in on the top right, which is also volume up and f12, when you press it on its own, is it supposed to control the volume or control the f12 assigned in expose for example. Mine was working normally it was controlling volume as I expect it. Now all my top fn keys control fn if you press them on their own.. to control volume I have to press fn?
I have recently put windows 7 professional on my aluminum macbook, installed all the drivers, and so forth. I hook up my macbook up to an external monitor, and use a logitech dinovo keyboard for a mac. However, when I am in windows 7, the function keys do not adjust volume, brightness, and any other of the functions.
Installed a new bluetooth keyboard today. Now my volume controls and other features on the F1 - F12 Keys do not work.Went into Keyboard Preferences and selected and deselected the [ ] Use All F1, F2, F3 keys as standard function keys. Regardless of the setting, the volume controls do not work. Even when holding down the [Fn] Key. I can adjust volume with the mouse ( new Magic Mouse ) using the control on the menu bar.
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.
Today I received a bluetooth Razr mouse in the mail today and went to connect the device as I would any other. Well when I was playing music in iTunes, the function keys to skip, pause, and every other function key does not work. The volume keys move my windows and pull up widgets. I dont know if the mouse has anything to do with it, but I imagine it doesn't because I disconnected it and the problem remains.
I was listening to music one day and went to pause the music using the Play/Pause (F8) key. I pressed the key and nothing happened. The forward skip and back skip keys also do not work with iTunes or any other program. I've tried resetting the key settings and restoring my Macbook Pro to a time when i remembered them working.
Info: MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.1)
The top row of keys on my keyboard are not working i.e. sound buttons do not adjust sound, same with brightness etc. They make a sound when pushed but the functions arent working. I have booted in safe mode and reset sound cache, I have check all settings in the keyboard section of system preferences.
Just recently the music control keys (the function keys 7-9) aren't working, all the other function keys work. The music control keys do not work even if I am in iTunes or if I set it to use function keys as standard function keys then try to fn use it. I just updated to Yosemite on Tuesday, I have turned my computer off twice since then and I restarted it today. I have a Macbook pro with retina.
Info: MacBook Pro with Retina display, OS X Yosemite (10.10.1)
It appears that the function keys to control iTunes/Quicktime (FF, Play/Pause, and RW) are not working. At one point they did but now it doesn't. All the other function keys are functioning just fine and dandy. I have the "Use F1, F2, etc. keys as standard function keys" unchecked in the preferences. I looked around and there doesn't seem to be any setting that would explain the sudden malfunctioning of the keys. Is there something I may have missed?
I have a Mac os x with the Windows vista partition. I downloaded Realplayer to view some videos on both the windows and mac side. When I did the latter I realized that this was the problem; all my function keys stopped working, I cannot control volume, eject, brightness, anything. I have uninstalled Realplayer from the Windows partition and the problem persists. I have tried to look into the systems folder and drivers, but I really don't know what I am doing and I don't want to make it worse.
I just bought a new wireless keyboard to use with my iMac. My function keys at the top of the keyboard are not working and when I try and fix them in system preferences, I am unable to. There is no option to get the rewind, play/pause, fastforward, mute, volume down or volume up to work.
On my new 15inch mbp the volume keys have suddenly stopped working. I checked in system preferences that the use F1 keys as standard is not selected. When I plugged in speakers or headphones the volume keys work as normal. But with just internal the little picture on screen comes up so the keys work but it doesn't affect the volume?
I just bought a 2.4 MBP model a1260. When I got home i noticed the volume keys were not working, and then i noticed none of the function keys were working properly. (example, f12 shows an eject CD symbol). So, the keys are working but not doing the standard functions such as volume and brightness. I have check and unchecked (and restarted) the "use all f1, f2 as standard function keys" to no result.Some other wierd things that seem to be related are:
1. In the SOUND window in SYS PREFS all sound effects are greyed out. Under OUTPUT and INPUT it says no devices found.
2. When i go to the itunes store in itunes and i double click on a song, it wont play. Not only is there no volume, but song wont play. Its the same with my own music from my cds.
3. When i insert a DVD no volume control shows up.
And the last superwierd thing (haha) is that I reloaded leopard and when the computer restarted up after install there was no OSX music that normally plays as the video flys thru the starfield.
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?
