Bluetooth, iSight and Keyboard Backlight not working. Please help!

My Bluetooth stopped working along with my iSight and Keyboard Backlight. I first noticed the weird sign over the bluetooth icon, and it read "Bluetooth not available". I payed no attention to it for a while until I tried to take a picture with Photo Booth and I read "No camera found", for some reason I tried to dim the backlight on the keyboard and a blocked sign appeared under the brightness level, not letting me do anything (Later I was able to use the backlight with the LabTick app). I have tried everything. SMC, PRAM, NVRAM, logging as diferent and new users, booting in safe mode... every solution I have found on the internet has been tested by me. Then I read this about the Hardware Test solution, and surprisingly after performing the Hardware Test no problems were found! So basically my MacBook Pro (mid 2010) is not having any trouble of any sorts with anything. Then why can't I use Bluetooth, iSight or Key backlighting (which only works through LabTick). Given the fact that the hardware test shows no problems I am not comfortable with the idea of taking it to repair. There MUST be something I can actually do to fix these issues.
Does anybody have any idea? I repeat, these are NOT WORKING, NOT FOUND AND NOT AVAILABLE.
- Keyboard Backlight (Only works through LabTick)
- iSight Camera (Not found by any software)
- Bluetooth (No info appears on the system profile, the icon on the menu bar is completely gone)
All three issues happened at the same time, the night before everything was working perfectly fine.
If anyone could help... please!!!
Summary:
MacBook Pro Mid 2010 (http://support.apple.com/kb/SP583) Unibody, can't take out the battery.
Solutions tried:
- Reset SMC: Turning on while holding Shift + Ctrl + Option + Power Button (This makes my MacBook forget about the battery and start up with really loud fan noise, battery icon appears with an X on it, keyboard backlight buttons work, they show brightness level on screen, but the actual light won't work, no bluetooth, no isight)
-Reset PRAM and NVRAM: Turning on while holding Option + CMD + R + P (I have waited for 2 chimes, 3 chimes and 4 chimes at different times, nothing happens. Light, bluetooth and isight are still gone)
-Holding Power Button for 10 seconds, 20 seconds, longer... nothing changes.
-Creating and logging in as new admin user, nothing changes.
-Deleting the bluetooth.plist file and powering off and on again, also rebooting
-Deleting the SystemConfiguration folder, powering off and on again, also rebooting
-Installing "blueutil", didn't help at all, turned it off via terminal with command blueutil off.
-Performing Apple Hardware Test - Shows no erros or problems on any area after one full hour of testing (Performed the extended testing)
-Leaving it powered off overnight
Please anyone help meee!! I can't afford going crazy!
Thank you so much in advance!

Wacom Tablet causes Apple wireless keyboard to stop working.

My Wacom tablet/pen causes my Apple wireless keyboard to stop working. While working on a photo in Photoshop using my Apple (usb) mouse to make selections the keyboard works fine. When I use the Wacom Pen to make selections, not immediately but anywhere from five to ten minutes into it, I hear what sounds like a chirp from my computer (Mac Pro) and my keyboard stops working. The command, option, control and direction keys still work but not the number and letter keys. I have to connect a spare Logitech keyboard via USB in order to continue and not loose my work. After awhile I will hear the chirp again and the Apple keyboard will start working. This will continue to occur at irregular intervals. Without the spare keyboard I've had to reboot my computer (loosing all the work on the photo) to get the keyboard working again, but only for it to reoccur. Any suggestions to fix this would be appreciated.

The Mac inherently keeps all input methods active, such that you could type alternate keys on alternate keyboards.
If you have third party add-ons that might change the way Bluetooth works, those would be the primary suspects.
Be sure all your Drivers are completely up-to-date, and batteries in battery-powered devices are still strong.
Bluetooth uses the same part of the frequency spectrum (but a different modulation technique) as cheap WiFi Routers, baby monitors, and microwave ovens. if you live in a busy apartment building, there may be very high levels of interference.

Problem with Macbook Pro early 2011, webcam not working in any apps and windows 7 or 8 on bootcamp, keyboard backlight not working?

Hi Guys
I recently bought a second hand early 2011 Macbook Pro 15 inch and are having 2 problems. The first is that none of the apps detects my webcam at all, the second is, i have Windows 8 installed on bootcamp but are unable to get the keyboard backlight to work in 7 or 8. The backlight works perfect in os x 10.8.5 though. I need a little bit of help guys.....

Go to Apple Menu / About This Mac. Click on More Info ... next on System Report. In the left hand column, under Hardware, select USB. The right side will show the USB Device Tree. Look through that and check for "Built-in iSight". That is your camera. If it is not listed the camera is not working.
For backlighting, try this: go to System Preferences / Keyboard. Uncheck "Adjust keyboard lighting in low light".

Keyboard shortcuts stopped working after upgrading to iOS 7

Does anyone know how to make the keyboard shortcuts start working again in iOS 8? After I upgraded to I OS 8 on my iPad air, the keyboard shortcut stopped working. Is there anyone who knows how to make this work again? All the fixes online pertain to iOS 7 and earlier, and they're not applicable for iOS 8.
Hope someone can help!
Thanks!

I lost all my keyboard shortcuts on my iPhone 5s after upgrading to iOS 8. They still showed up on my iPad Air (iOS 8) and iMac (10.9.5). There were, however, massive sync problems, sometimes they would only flow from one device to all the others, sometimes from one device to only one of the other two, sometimes not at all.
I deleted all my shortcuts and started from scratch, deleting “~/Library/Application Support/Ubiquity”, ~/Library/Dictionaries” and “~/Library/Mobile Documents/com~apple~TextInput” from the iMac and KeyboardDomain from my iOS devices.
Rebooted everything a dozen times.
Toggled Documents & Data Sync off and on a dozen times too in all kinds of combination with rebooting and deleting the aforementioned files.
Everything always starts working and syncing fine for a very short while, but sooner or later one of my devices stops receiving new shortcuts as I re-add them.
I reboot that device and it catches up. I enter new shortcuts, and that device doesn’t get any new shortcuts. This time, a reboot doesn’t fix anything.
After using my devices for a while, I notice shortcuts are entirely gone from both the iPhone and iPad, but not from the iMac.
I even upgraded my iPhone 5s to a 6, and right off the bat it had issues with keyboard shortcut sync. I also setup my iPad as new, and same thing: right off the bat, sync issues with keyboard shortcuts.

Keyboard Backlight not working anymore.....please help.

After installing Boot Camp 2.1, I can't get the keyboard backlight to work anymore. I am in the darkest of dark rooms. Pressing F8 just shows an attempt to turn it on but it has a circle with a line through it.
I am running Windows Vista 32-bit SP1.
Are there drivers I can install manually?
Thanks.

Here is something funny. I rebooted with the room completely dark. When Windows came back, the keyboard was backlit. But, when I turned the lights on, the keyboard stayed backlit. And, even better (or worse), when I rebooted again, the keyboard just stayed backlit even to the point where I was choosing between booting into OS X or Windows. That is crazy! I don't know what is going on anymore.

My keyboard has stopped working. How do I fix it?

Hello!
Today I got back to work after my summer vacation and for some reason my keyboard has stopped working.
I tried with my collegues keyboard but that didn't work either.
The keyboard works if I give my virtual machine in Parallels direct access to it, but not in OSX so it's probably not a hardware issue. (This is how I am writing this)
The caps-lock light works even when connected to osx. Mouse works perfectly in osx.
I am running 10.6.8 on a Mac Pro 2x2.8ghz xeon 12gb RAM.
Any ideas?
Thanks a bunch!
/Hannes

I upgraded to Mountainlion and the problem not only persisted, but also worsened.
Any button I pressed, it restarted.
I have removed a couple of apps I had installed, for example Double Command which I think might have been the culprit, and now the computer works fine again.
Big relief!

HT2452 my imac keyboard has stopped working? help!!!

my imac keyboard has stopped working??? help!!!!!

My keyboard just stopped working out of the clear. One minuet OK next it was dead. No little green light at all. New batteries did not help.
FIXED THE PROBLEM! I took a small piece of aluminum, made a little ball out of it and dropped it down the tube where the batteries go. Replaced the batteries I had just used......little green light comes on and the the keyboard functions like always.
My guess is after a few years the contacts oxidize a bit and don't make contact with the batteries on the bottom of the tube. Give it a try.

Camera switching keyboard shortcuts stopped working

I'm working on a multicam sequence, and I can switch cameras by clicking on the different shots in multicam view, but using the 1, 2, and 3 keys on the keyboard no longer switches the camera while I'm playing through.
I've tried changing the shortcuts to different keys, but that didn't fix anything.
Anybody else run into this issue?
I feel like it's probably a toggle I inadvertently hit somewhere, but I have no idea how it happened.

Thanks for the quick reply, but unfortunately I don't think that solves it.
If I have the multicam sequence paused, and have the clip selected on the timeline, I can switch between camera angles with no problem.
However, as soon as I start playing the sequence in the multicam monitor, the keyboard shortcuts stop working.
Also, the only keyboard layout I have installed is US English.

The "enter" key on the numeric keypad of my external mac keyboard has stopped working. Help!

The "enter" key on the numeric keypad of my external mac keyboard has stopped working with my Macbook pro. If I plug the keyboard into any other computer, that entier key works fine. I'm using a standard Mac wired keyboard, & it's worked fine for 2 years now. Help!
This is the keyboard I am using: http://store.apple.com/us/product/MB110LL/B/apple-keyboard-with-numeric-keypad
Not sure what I might have accidentily done to disable the enter key. (The normal enter key works fine, just the one on the numeric keypad.)
Thank you for your help.

Hi there,
Do you have any resolution to this problem in the end? Because it happened to me an exact same thing.
Please share if you have found a solution to your problem. I also cannot think of what I did wrong to disable the Enter key.
Best Regards,
Jeffri
