Software :: Apple Bluetooth Keyboard Stopped Working / Itunes Stopped Working

May 13, 2009

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...

MacBook Pro :: Keyboard Backlight Not Working After Disassembling

Apr 18, 2012

After a little spill of coke, my keyboard becomes sticky. I bought new one from ebay and replaced it. Everything works fine except keyboard backlit. I tried basic solutions such as  SMC reset, check cabling again but not worked. 

i behaved very politely while disassmbling and assembling but now i start to suspect that kill backlit somehow.

MacBook Pro :: Keyboard Backlight Not Working After Small Spill

Aug 6, 2010

I was drinking some tea and bumped into the table the mug was sitting on. A couple of drops splashed out and got on my unibody macbook pro's keyboard. I quickly wiped it off and turned off the computer. I let it sit for a while, but I didn't think anything of it because it was only a few drops. I turned it on and it was fine, however the keyboard's backlight is dim on the right side of the keyboard.

MacBook Pro :: Keyboard Backlight Not Working - OS X Mountain Lion (10.8.5)

Dec 9, 2014

Well, after my keyboard backlight going out, and me looking for multiple solutions, I've found multiple solutions on the internet that include deleting the file from the Library file. My issue is, I'm actually missing this file from my Macbook pro, which leads me to believe that this is the main reason that my backlight isn't working. Is there anywhere I can find this file, or any reason why I'm missing this?

Just to add in, I have a corrupt Hard Drive, and plan on fixing it soon. Could that have anything to do with it?

Hardware :: Keyboard Backlight Not Working?

Feb 19, 2009

I own a MacBook Pro 5.1 (late 2008) and since a couple of hours my keyboard backlight suddenly turned off and I can't reactivate it anymore. When pressing the corresponding buttons which regulate the intensity of the backlight I get only the backlight icon on screen with a not available button attached to the lower corner. Is anyone familiar with this problem by chance? This happens under both OS X as well as Windows XP.

Aug 18, 2009

The backlight for the keyboard on my powerbook G4 isn't working. It worked perfectly a few weeks ago. Now when it is completely dark in the room and I turn the backlight all the way up the keys dont light up. Do the backlights on these keyboards really break?

Software :: Keyboard Backlight Sensor Not Working?

Jun 14, 2010

My Macbook Pro keyboard Backlight is not working properly even in a darkroom.

I need to install a third party software (Lab Tick) to switch on the keyboard light.

I am not able to use F5 and F6 key to adjust the light dimness. I suspect the light sensor is having problem.

However, last night I received an error message, saying that my Mac is having problem, I need to press the Power button to restart the Mac.

After restart, the keyboard backlight is working (without Lab Tick), and I can adjust the light with F5 and F6.

But now,after I made the Macbook sleep and wake up, it's back to abnormal again.

OS X :: Keyboard Stopped Working / Restore Back To Earlier Version Of Keyboard Firmware?

Feb 28, 2008

Yesterday I had a Leopard software update which included new keyboard firmware. I did the update and the keyboard continued to function normally. This AM I booted my MacBook Pro and discovered the keyboard no longer responds to inputs. However, the MB does responds to an external USB keyboard.

Now I don't know if I have a sudden hardware problem or the MB keyboard is not working as a result of the firmware update. Has anyone else experienced a similar problem? Can I go back to the earlier revision of the keyboard firmware?

Hmmm - while writing this I just realized I have a bootable image of my system made a few week back on an external drive - I'll have to try it.

OS X :: MacBook Trackpad And Keyboard Stopped Working Suddenly

Feb 10, 2009

It seems that during my afternoon class, I shut down my macbook and then when I went to use it about 10 minutes later the keyboard nor the trackpad works. Now the keyboard/trackpad is not defective as it works via the OSX install cd and it works in Windows Vista (dual booted) When ever I start up OSX it just comes up and the mouse is in the upper left hand corner, and the keyboard doesn't work at all. I have tried a pram reset by pressing command + option + p + r and that did nothing. When I am in OSX the only way to get out is to hold down the power button till the macbook turns off. What else could be wrong is there anything I can do, the nearest Apple store is about 80 miles away so I am trying to avoid that at this point as it seems like a software issue.

MacBook Pro :: Top Most Line Of My Keyboard Suddenly Stopped Working?

Jun 11, 2010

Two or three days ago, the topmost line of my keyboard (contains esc, brightness, expose, dashboard, play/pause, mute, eject, etc.) suddenly stopped working. Strangely, some of the keys have switched functions: expose opens a search bar, keyboard dimmer refreshes the webpage, keyboard brighter selects the web address, play/pause is now shows Spaces, skip forward is expose, and sound increase is dashboard. I reset my keyboard, but nothing changed.

MacBook :: 10.5.6 Keyboard Stopped Working - Feels Like Virus?

Mar 15, 2012

This week, my macbook keyboard started becoming erratic, then became much worse.  Basically, it started with the tab key not working, then the keys 'r' and 'a' and 'v' stopped.  It felt like a virus, although I cannot seem to find many people with similar issues. Progressively, the keyboard has got much worse, to the point that it cannot now be used. Bizarrely, if I plug in a USB keyboard, as I am using now, then I am able to type without any issue. 

I have searched forums and have done the basic stuff - reset my PRAM, reset the SMC (although I am not sure whether this was done properly, as resetting the SMC was a basic exercise, unlike PRAM reste where a noise indictaed it having been complete). I feel that the next step is to do a complete reinstall, but I don't want to do this if possible, as I don't know how it will affect the lion install etc.

MacBook Pro :: Illuminated Keyboard Stopped Working / Not Producing Visual Feedback On Screen

May 9, 2008

suddenly, my MBP (2.6ghz, 15") illuminated keyboard has stopped working. out of the blue. same conditions in the room as when it's worked before - so it's not an ambient lighting problem. the functionality is all turned on, and pressing the dim/brighten keys on the keyboard, while producing visual feedback on the screen (like the volume indicator), produces no illumination on the keyboard. im plugged in, fully charged... can't figure it out!!!

to be honest, i never really use the keyboard illumination, but now that its actually not working, its really bothering

OS X :: Keyboard And Trackpad Stopped Working - Fixing It?

Mar 18, 2009

Today I was working with some work and put my laptop to sleep by shutting the lid. Less than half an hour later I opened it and the keyboard and trackpad were both unresponsive. I tried everything but nothing worked so I shutdown the computer by holding the power button down. I then restarted it and they still wouldn't work so I was unable to login. I have also tried an SMC reset but this was to no avail either.
