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.
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).
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.
I'm using the thin aluminum USB external keyboard and suddenly my 8ik, diagonal of keys stopped working (now I'm using my laptop keyboard). Anyone know if this is typically a sign of a broken keyboard, or a user issue?
I spilled some water on my laptop this morning but it wasn't a lot and seemingly nothing happened. Then several hours later all of the sudden my delete key and arrow keys are not working. I can only assume this has something to do with the spill. My MacBook Pro is over 2 years old and I'm pretty sure the warranty is long expired. I definitely can't afford a new one or expensive repairs. Is there anyway to change the function of my keys? In other words can I change say one of my shifts or command keys into a new delete key ?
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.
I can't backspace anymore. And just now, as I type this, I noticed if I press delete I -forward- delete, and I can still highlight text and delete it that way. How do I change the delete key to backspace? Also, my arrow keys used to move the cursor within text. now it just scrolls the page up and down.
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?
my work MacBook Pro and my own MacBook Air - The media keys have stopped working. Dumping the prefs and restarting haven't worked. The media keys work fine with Spotify though. My software versions are below:iTunes 11.2.2 (3)OSX 10.9.3
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.
I installed 10.5.7 yesterday. Immediately after the installation was complete, my Apple bluetooth keyboard stopped working. Went into Bluetooth system settings, and it said that there was no bluetooth hardware found... (it's built into the machine!!)...
Also, every time I start iTunes, it gives some weird error about Adobe Flash player. I'm not at home now so I don't have the exact wording of the error with me, sorry...
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.
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.
F3 and my right shift key have suddenly become play/pause keys in addition to their original functions. My F8 doesn't really do anything anymore and does not even light up in Keyboard View. I've tried to use Sizzling Keys, and reset Keyboard Shortcuts but the problem still persists. It seems to affect most music playing programs (iTunes and Vox. I have a Macbook Model 5,2 and Mac OS X 10.5.8
I recently spilled a protein shake over my mb pro. It spilled on the right side, but I quickly cleaned it with a wet tissue and dried it up. The problem, now, is that the illuminated keyboard isn't working..only a few random keys are working and the rest aren't..
What should I do? I have a 1 year warranty left, but I'm not sure it'll be covered.
I bought my first Mac computer last month, the 13" 2.4 variant. Loving it so far.I have lately noticed however that my ambient light sensor is not much of help. Before, after coming out of sleep I could notice the screen changing to accommodate for the room's light output. I could also put my hand over the sensor near the iSight and witness the brightness decrease in front of me.
