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.
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.
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
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 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 bought a new MacBook Pro i5 yesterday to replace my MBP LED (2.2Ghz). The function keys on the new MBP kinda suck. I really want the one that does "Show Desktop". If you go to keyboard layout, it says that F11, F12, etc., are assigned, but seems it completely ignores them. What the F? Even if I could change the expose button to show desktop, I'd be very happy. I know you can use the 4 finger swipe, but that doesn't help while trying to drag something from the desktop into mail.
all the normal keys on my mac keyboard worked fine on friday when at work and i come in today and they are all messed up. how do i get them back to there defaults? Example, f12 now goes to the desktop instead of actually increasing the volume and f11 is the dashboard instead of decreasing the volume, etc. I am not sure if an update or something got installed or what. I have tried going into keyboard under system preferences and restoring defaults but that didn't work. I also tried powering the keyboard off and on and still a no go. I am using the bluetooth keyboard and running snow leapord.
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.
I have a PowerPC G5, OSX 10.4.11 with a wired numeric keyboard. I enter a lot of numbers. How can I assign one of the function keys on the right side of the keyboard, above the number pad, F16, F17, F18, or F19 to be a "TAB" key so I can move around fields when entering numeric data?
I've been using itunes for a while and it just messed my entire music library up! I've found something that is more Winamp style for me named "Cog". Now my problem is that I want to control it with the F7, F8, F9 keys which are the rewind, play and forward keys, but when pressing any of them it works both on itunes and cog player. How can I disable the Itunes link to it? I want it to control only Cog player.
I recently received a bluetooth ultra-thin keyboard to use with my laptop while I have it hooked up to it's external monitor, the only trouble is that I can't seem to get the function keys to work properly. I've managed to go in and reset the dashboard control / brightness using the keyboard pane in the system settings, but I can't seem to set the volume / media control buttons. Any ideas how to get my keyboard working properly? If it matters at all, I'm running this on a 2.4 unibody MBP.
If anyone is experiencing problems with the function keys on the new aluminum wireless keyboard, I have found a fix. Download and install the Wireless Mouse Software Update from Apple's support page.
Or rather I'll provide you with direct links: 10.5 Leopard: [URL] 10.6 Snow Leopard: [URL]
Download those, restart your computer and WHAM you'll have a bluetooth ultra thin keyboard with functions buttons that actually work. THE ISSUE: For some reason Apple computers recognize the new Aluminum keyboard as the old white keyboard. I discovered this by turning on keyboard viewer and realizing that the keyboard represented on screen had a numpad while mine did not. Supposedly Snow Leopard has an update already which recognizes this, however, we have all found that to be false. Install the mouse update and it'll all work out.
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 want to be able to access the function keys for word processing commands. I want to use one key command, not two. I am presently using a Macally keyboard that is several years old. (I like the feel for typing.) System preferences allow for one key commands, but do not work with this keyboard. Would a newer keyboard work? E.g., the Matias OS X Keyboard? or the Macally iKeyS?
firstly, i have recently got a new apple keyboard and the function keys on it have got messed up. it has the logos for things like pause, volume and brightness, but when i click them, they dont do what they say on the key. secondly, i have also recently got a magic mouse and you are meant to be able to swipe to scroll and thing like that, but that doesnt work either.
When I try to use the volume keys on my iMac keyboard (not wireless), it brings in my different desktop windows instead of controlling the volume. However, I can still control the volume using the volume icon on the main desktop - just not from my keyboard. I am not very technical, but I read about resetting the PRAM settings, which I tried.
(Also, earlier in the week, the USB port on the keyboard for my mouse also stopped working, but now it appears to be fine. I'm not sure if this is related or not.) All software is up to date. I am on Mac OS X version 10.5.8.
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.
I recently upgraded to Snow Leopard on my Macbook Pro (early 2008) and now my function keys are mixed up. My volume keys are now F3 and F4 for example.
I have already unchecked, �Use all F1, F2, etc. keys as standard function keys� as standard function keys� in System Preferences and it didn�t fix the problem. Also, under the keyboard shortcuts tab I have clicked the �Restore Defaults� button. This also didn�t fix my problem.
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.
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.
