Wifi, Bluetooh and iSight not working MacBook Pro

I have a mid 2009 MacBook Pro Unibody. 8Gb Ram  Mavericks OS. I powered down one evening, everything normal.  Next day I rebooted it to find that I had lost Wifi, Bluetooth and isight.  Oh, and the fan runs at high speed constantly.
Ptheise computer is running OK and I can connect to network via ethernet.
Messages are:
1. Wifi - no hardware installed
2. Bluetooth - not available
3. iSight - there is no connected camera.
I have rebooted in safe mode, reset NVRAM and SMC, left it off for 30 hours. Tried an AHT. None worked.
Have checked system information.  Responses are:
1. WiFi
Software Versions:
  CoreWLAN:          4.3.2 (432.47)
  CoreWLANKit:          3.3.2 (332.36)
  Menu Extra:          9.3.2 (932.35)
  System Information:          9.0 (900.8)
  IO80211 Family:          6.3 (630.35)
  Diagnostics:          3.0 (300.40)
  AirPort Utility:          6.3.2 (632.3)
2. Bluetooth
No information found
3. Camera
No video capture devices were found
I'm presently redownloading Mavericks to do either a reinstall, or clean install, but before I do this can anyone suggest a solution?  Computer back up is up to date.
NB: I live in Botswana where there are no Genius bars, nearest reliable service is in South Africa and downloads are VERY slow.
Thanks in advance

Restarting Mac may fix it.  Otherwise: http://support.apple.com/kb/HT2090
(Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD."  Regardless of the name of your built-in camera, the same info and troubleshooting applies.)

    hi my iphone 3gs wifi, bluetooth and imei not working

    Do you have modified software installed on your device?
    If not, try to set it up as new device, explained here, without using the latest backup afterwards, in case it is containing corrupt data.

  • Microphone and Line In Suddenly Not Working Macbook Pro 15" Early 2011

    Yesterday without warning, my internal mic stopped working on my Macbook Pro 15" Early 2011. I discovered this when the recipient of a Skype call couldn't hear me, and verified that the mic was not getting any level in the Sound system preferences pane. There is also no microphone input happening when I plug in my iPhone headset to the headphones jack. The audio out seems to be fine. I had to use a USB microphone to get any sound into the computer. I used the microphone just a few days ago without any issue.
    I've already tried:
    Rebooting
    Resetting PRAM
    Creating second account to test audio
    And none of the above had any affect. Other note: I recently had the GPU of this computer replaced under Apple's special replacement plan. Anything else I should try before making an appointment to have the hardware looked at?

    pushyourmind,
    If you’re up-to-date with Software Update, then you have the correct firmware installed. If you’re running 32-bit Windows 7, then Boot Camp Support Software 4.0.4033 contains the correct drivers; if you’re running 64-bit Windows 7, then Boot Camp Support Software 5.1.5621 contains the correct drivers. Which ever support software corresponds to your version of Windows 7, try downloading the corresponding .zip archive and following the installation instructions on the corresponding link above when booted in Windows.
    Boot Camp 5.1 supports Windows 8.1 on your model MacBook Pro if you’re running OS X 10.8.3 or newer. Earlier versions of Boot Camp and older versions of OS X don’t support Windows 8.1 in Boot Camp on your model MacBook Pro.

  • Bluetooth not working macbook pro 2011, AHT found nothing

    My macbook pro 2011 has been having some issues with bluetooth. The system doesn't even recognize as having bluetooth hardware. I went under the hardware profile and it actually says No information found under bluetooth. I was able to do a full hour diagnostic test using Apple Hardware Test and everything was all clean. I'm not sure if this is Yosemite related or not. I definitely remember using my bluetooth enabled keyboard and mouse on my system before I upgraded to Yosemite. Wifi works fine. I've tried resetting PRAM, but nothing. I'm at a loss, not sure if there is anything else I can do.

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
    Keeping your confidential data secure during hardware repair
    Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
    *An SSD doesn't need to be zeroed.

  • Facebook Videos and Isight not working.

    Every time I go to leave someone a video on facebook with my built in isight camera, I am able to record the whole video, but as soon as I hit stop to recording the error message comes up "An error occured. We were unable to save your video. Give it another shot."
    I know my video works because I use it on Photobooth, and skype and ichat. It's just facebook that I can not leave videos for some reason and I want to know why.

    Welcome to Discussions, awrig537
    I tested and saving video recorded with my iSight works for me now.
    Try restarting your Mac and testing FB video again with no other apps running.

  • HDMI output not working MACBOOK Pro (Oct 2014)

    I am trying to get another screen connected to my MBP, I have tried numerous screens and cables to achieve this, but I can not get it to work.
    Is there a on/off or disable HDMI output on the MBP?
    I have used various screen, which i know work. And a HDMI to DVI and HDMI to HDMI cables to screens . I know the cable and screens work as I use them at work on a daily basis.
    All I get is "No signal connected".
    Is there any diagnostics or tests I can do?

  • Flashing Question mark: New hard drive not working Macbook Pro late 2008

    After following several peoples advice on this forum I decided to upgrade my Macbook Pro late 2008 with a Seagate (1TB) Solid State Hybrid Drive 2.5 inch.
    Heres the device.
    http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
    After creating a mountable boot on a External hard drive with Mavericks install I removed the current hard drive and replaced with the new seagate drive. However it didn't seem to recognize the external hard drive (it is quite old but works perfectly) and went to a flashing grey question mark screen and wouldnt do anything else. Ive tried holding down command-r and option-r but I get nothing. Its just the same flashing question mark. I have done this several times and the same result.
    I put the old drive back in and it works fine.
    I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer?
    Appreciate your help
    Gary

    Sorry I think you may be confused.
    I am trying to install the new Seagate hard drive to my mac (not as an external hard drive).
    I replace the macbook pro hard drive with the seagate drive:
    http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
    I then started up the machine with a usb external hard drive with a boot copy of mavericks on it. However, it just displayed a flashing question mark and wouldnt start booting the osx.
    I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer? Im guessing it must be hard drive. Would it be better to use a USB pen drive as the external hard drive is quite old?
    Does anyone know what the problem could be as the hard drive is brand new.
    Appreciate your help
    Thanks, Gary

  • Audio not working MacBook Pro 15''

    My internal speakers are not working and seem not to be recognized by the OS. I am running Lion. Under Preferences>Audio there isn't any option for the internal speakers. Headphones are still working.

    I had the same problem and after a bit of research discovered that the line in is not getting enough input from an unpowered set of headsets.  ALSO, the mic level was set too low and so nothing was being picked up.
    Solution:
    I have a Thunderbolt Express Dock (expensive I know but very handy) and plugging in through the express dock with the mic level up works great.
    Alternatively, I also have a USB Headset Connector that comes up as a seperate device and also is able to take inputs.
    Finally, if neither of these work, I found that the earth chassis on my Macbook Pro 15" was a bit unpredictable.  I removed the base cover, cleanes the contact points (little silver spring loaded buttons on the edge of the main board) and where the contacted the cover and this also improved things.

  • Speakers not working - Macbook Pro

    Hi,
    Am facing this issue from today, that speakers on Macbook Pro are not working, when am MAC OS. When I boot into Windows 7 (Bootcamp), the speakers seems to be working.
    I have checked the mute key, to ensure the MAC is not on mute mode.
    How can I debug this issue?

    Resetting Mac's PRAM and NVRAM did not helped.
    Then I checked Sound settings in System Preferences and in Ouput Tab, the value selected for Sound Output was Apple TV. Probably it got changed when I was streaming the conten yest. using Apple TV.
    I changed it back to Internal Speakers and and got the sound back on speakers.
    Thanks for all your assistance.

  • Backspace key not working - Macbook Pro using Mavericks

    I've got a Macbook Pro (early 2011 model) which I upgraded to Mavericks earlier this year and all has been working fine. Over the past few days I noticed my backspace key was playing up (sometimes it worked, other times I had to press hard a few times before it would work at all) until today when it decided it would not work at all. I have already checked in System Preferences and restored defaults as well as resetting the PRAM but to no avail so far. Is there anything else I can try or will I need to take it back to the store and get it looked at?

    Since you reset the PRAM, I would take it in for diagnosis.

  • Boot Camp: Keyboard and iSight not working

    I am a recent Mac convert and just installed Leopard on my MacBook Pro. After going through the Boot Camp installation program I installed Windows Vista Business. Now, when I boot up in Vista my iSight is not detected and my keyboard will not illuminate.
    I tried reinstalling the drivers off of the Leopard DVD but to no effect.
    Help!

    I'm sorry that you are in the same situation. I removed the partition and started the whole process again, reinstalled Vista, added the Boot Camp drivers from the DVD and then went back and added the specific keyboard and iSight drivers individually but NOTHING changed.
    If anyone has any suggestions they would be much appreciated.

  • USB and iSight not working

    Hi, I've been having some issues with my macbook:
    (1) My front USB port is not working. I've been getting the following message everytime I restart (even when nothing is pluged in): "Becayse a USB devide was drawing too much power from your computer, one or more of your USB devices have been disabled". I've tried resetting the PRAM and SMC, this does not work.
    (2) My built-in iSight no longer works. I tried using skype and photobooth and the camera is not detected. I looked in my system profilers and isight is listed but I'm not sure what this information tells me (see below):
    Built-in iSight:
      Product ID:          0x8507
      Vendor ID:          0x05ac  (Apple Inc.)
      Version:           4.42
      Serial Number:          8TA5B04NPDCJ6F00
      Speed:          Up to 480 Mb/sec
      Manufacturer:          Apple Inc.
      Location ID:          0x24600000 / 2
      Current Available (mA):          500
      Current Required (mA):          500
    (3) My battery drains when my macbook is in sleep mode (this was not happening before).
    (4) My computer seems to be getting really hot. This cause the bottom rubber of my macbook to start peeling off. I've downloaded iStat to keep and eye on the temperature but I'm not sure if this is related to my other issues.
    Does anyone have any idea what could be causing this? Are there any tests I can run? I'm not sure if these issues are related or not. Please help.

    According to the AHT instructions on p. 61 of the manual for your 13-inch Mid 2010 MacBook, http://manuals.info.apple.com/en_US/macbook_13inch_mid2010_ug.pdf you did the correct restart process.  To me, the fact that AHT does not work either is one more indicator of likely hardware trouble.
    chantal102 wrote: ..  I would like to try everything I can do myself before bringing it in...
    If nothing else you try fixes your issue, try restoring your Mac's software.  If neither a Time Machine restore nor a complete restore to factory original condition (p.60) corrects your trouble, I think you are left with the choice of AASP service or deciding whether it is time for a new Mac.

  • Audio and Camera not working Macbook air

    I got my macbook air as a present from a relative and it seemed to work nicely even though I think it was used before. I took pics and watched videos on it before, but all of a sudden the sound would not work so I would restart my laptop and then it would work again but now even restarting it wont work the option to use the built in speakers is not there anymore. I wanted to facetime my friend and it says no that there is no connected camera. I do not know what to do.  I really want to get back to watching stuff and taking pics please help me !!!!

    Hello fridamente123,
    Thanks for the question. After reviewing your post, it sounds like the iSight camera and internal speakers are not working. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.
