10.5.2 upgrade lost Bluetooth module

Leopard no longer finds the Bluetooth module on my Intel (Core Duo) Mini after installing the 10.5.2 upgrade. Attempting to install a new BT device brings up an error box saying that no Bluetooth hardware can be found. Looking at System Profiler -> Hardware -> Bluetooth gives "no information". Rebooting into 10.4.11 restores all BT functionality. The Leopard/BT loss is 100% reproducible.
I've seen several threads about BT keyboards freezing intermittently after the 10.5.2 upgrade, but didn't see any saying that the BT module is no longer recognized. I have left a report with Apple. Has anyone else experienced this, and if so, did you find a fix? Thank you.

And to add more information to my prior post, Airport is also nonfunctional after the 10.5.2 upgrade. Unlike the bluetooth problem, System Profiler sees the Airport card, but trying to configure the Airport under Network fails. The button to turn the Airport on is greyed out, and I haven't found another way to turn it on. I've tried resetting PRAM and SMC, rebooting, creating another user account. I've also re-installed 10.5.0 (archive/install), and that brings back both Bluetooth and Airport operation. When I then apply the 10.5.2 combo updater, the OS can no longer find the BT hardware module, and the Airport card can't be turned on. Rebooting under Tiger fixes it all, so I think I'm safe in saying it's the 10.5.2 update that's breaking things.

MB Lost Bluetooth Module

Recently my MB somehow lost its Bluetooth Module. I have no idea how this happened because for the past month my Bluetooth mouse has been working fine, and today when I booted up my computer my mouse would not connect, so I went to system preferences and a message popped up that said, " The bluetooth tab has been hidden because there is no bluetooth module installed or attached to your computer." Do I need to have it repaired or is there something I can do to fix it?

I had a similar problem myself a couple months ago. It appears as though the software had been completely removed. I called Mac support, we went through multiple steps, and finally, after multiple restarts, the tech guy had me restore default settings to the computer and then unplug everything from it, including the battery. This turned out to work.

Lost Bluetooth module

Hi,
I've got a new iMac Aluminum 20"... After I unbox it and install all the updates (10.5.7 and some firmware update) I realized that my bluetooth icon in the status bar was missing...
I opened system preferences pane and there was no bluetooth there either...
When I tried to use the bluetooth file exchange app this came up on the screen:
Then I opened the system profiter to look for the bluetooth module information it said I don't have a bluetooth module...
Is this a hardware problem and I should take the computer back to the store or it's a software problem??
Please someone help me
Thanks....

Thanks from me, too...
Mine disappeared when I'd shut down the laptop for about 15-20 minutes. Restarted with the install disk, ran disk utility, and on the second restart it was back.
One question: I couldn't get my MacBook Pro, OS 10.5.8 (just got it in July) to give me startup options when I held down either the D or C during a restart. (I've used it with bootcamp partition, and it works there). However, when I went to startup prefs, the install disk was there as an option.
OK, one more question: I didn't see anything that said "diagnostics," only the utilities menu that has the disk utility. Don't recall ever seeing "diagnostics," actually, in any Mac version, especially not hardware diagnostics. Am I missing something, or is the reference generic? (Note, though, that running disk repair from the install disk apparently solved problem).

I lost bluetooth when I downloaded the Yosemite upgrade - my BOSE Wave no longer connects

Yosemite upgrade disabled bluetooth

(Macbook Pro Retina 13") 10.10
Ok, A few updates ago Apple resolved this problem and its been fine up until I updated to Yosemite...
Before my wifi and bluetooth were 'fighting' if my bluetooth was on my wifi wouldn't connect unless i did it maually...
NOW
My Bluetooth speaker won't connect at all now... and the wifi also disconnects itself.
Is anyone else having this problem?
Other apple problems include,
1) My iPhone 5 shows 'no service' (for 2 weeks now)
2) when i open multiple pictures they're meant to open in one window but often open in separate windows!
Thanks!

Bluetooth module lost

When I started up my computer this morning it wouldn't recognize the wireless keyboard and mouse. When I went to re-setup the bluetooth it told me there was no bluetooth hardware installed. I can't find the bluetooth module anywhere on the system. I've restarted, zapped the PRAM, unplugged usb devices, except for an older keyboard and mouse. In the system profiler under bluetooth it says no information found. Not sure what else to do...any suggestions? Can a bluetooth module go bad?

FYI.....I did get the bluetooth to work....but a few days later it did it again. This time I had no USB devices plugged in except for a hub. I did unplug that but I also changed the batteries in both devices. Bluetooth worked upon restart. So...I think using new batteries is the key. Once they get a little low the bluetooth devices start to act up.

While installing Lion my Bluetooth module disappeared. How can I reinstall it?

While installing Lion my Bluetooth module disappeared. How can I reinstall it?

You ought to get a dialog asking to install the first time you run an app that needs it
Details here:
http://www.macworld.com/article/1167855/installing_mountain_lion_what_you_need_t o_know.html
The relevant bit is this:
Note that the first time you try to load a webpage or run an app that requires Java, Mountain Lion will prompt you to download and install the Java runtime, even if you upgraded from Snow Leopard or Lion and you’d previously installed Java. This is normal—you shouldn’t worry that installing Mountain Lion somehow “lost” any of your data or apps.
Or you can go to the Apple Downloads page and search for Java

IMac 5,2 Core2Duo lost Bluetooth - Fixed

This may apply to all Macs, but I have only one iMac that has lost Bluetooth so it was only tried out with that.
Our older white iMac 5,2 lost Bluetooth one day - no warning, no reason, it was just gone. I read the forums and tried everything, resetting SMC or what ever, re-installed the original Mac OS that came with the iMac, nothing made any difference.
I took a punt on a £2 Bluetooth USB dongle from Amazon, what do you know it actually works! It is seen by the iMac as if it was the original Bluetooth hardware, uses the built-in drivers. I don't know at this stage how well it's going to work over the coming weeks or months, but it's looking good as it will only be used for Apple keyboard and mouse (from the same period), and they paired without any problems.
The actual name of the item on Amazon was Super Mini USB Bluetooth 2.0 Wireless Adapter Dongle - OEM, I'm sure a simple search would find it.
For all those losing Bluetooth, after having tried the suggestions in these forums with no luck I would say give this a try. I plugged the dongle directly into the back of the iMac, this is not a problem for us however as it effectively replaces the wired USB connection that the original keyboard used.

And to add more information to my prior post, Airport is also nonfunctional after the 10.5.2 upgrade. Unlike the bluetooth problem, System Profiler sees the Airport card, but trying to configure the Airport under Network fails.

HP integrated bluetooth module in Pavilion dv7-2173cl Entertainment Notebook PC support A2DP?

Is my 2009 internal bluetooth module out of date? Can I upgrade?
I can connect an external bluetooth speaker, but windows is unable to find drivers. According to HP.com, the drivers are up to date. The icon for the speaker shows up in Devices and Printers window, but with a yellow error triangle. It seems pairing is successful up to a point; I just can't use the bluetooth peripheral. I know I can buy an external usb dongle that may or may not work, but I want don't want to have another external usb dongle as I have one for a mouse.

SillyBilly1,
Sorry for not replying to the second part of your post.
I didn't notice it until after I hit post and then I had to do some research and there is not much documentation which devices are A2DP.
From talking to people, your laptop Bluetooth will support the A2DP.
The device that you are trying to connect the laptop will be what has the restriction on it.
Let me know how everything goes.

Is there any Bluetooth module for Satellite A100-225?

Hello
I am wondering if a bluetooth module exists for a Satellite A100-225 (PSAA9E Series). What model?
Thanks

No, unfortunately this notebook does not support the internal Bluetooth module and it cannot be upgraded with such module.
If you want to use the BT technology you will have to switch to external solution.
Buy simply an USB Bluetooth stick. Such sticks are simply to use. Just plug in the USB port and configure it.

Airport / Bluetooth module replacement - MacBook Pro

I upgraded Bluetooth module in a 2010 MacBook Pro, after doing so, I get a no Bluetooth device available message. My wifi, which I believe is part of the upgraded module, works perfectly. With that new module not working, I then reinstalled the old Bluetooth card and the message still appeared and Bluetooth was unavailable. I tried the resets outlined in many posts including SMC and PRAM. I am using yosemite. To help clarify, both cards are showing in system profile when they are installed in the network section. Bluetooth is where it says is missing. Any ideas?

Well ... the first question is are you sure that upgraded Bluetooth module you installed is supported by your 2010 MacBook Pro? I believe after a certain year, these modules are combination Bluetooth/Wi-Fi cards. Prior to that, they were separate. I don't believe the combo card can be used in this case.

Internal BlueTooth Module???

Hi,
I never ordered my Powermac G5 with an internal BlueTooth and I would really like to get one, so I was wondering if anyone knows if Apple sells it directly or I have to take it to a Authorized Service retailer? Anyways I bought it in 2005 in June/July and it's a Dual 2.0 with a max of 4gb of Apple ram...also if anyone knows what the model number of the BlueTooth module for my model that would be great!

The other option is to buy a USB bluetooth module (Like "D-Link DBT-120 USB Bluetooth adapter") – which is sold on the Apple Store (or you can always shop around.
I've done this with my G5, and it works like a charm plugged into the back of my keyboard. You'd never know it was there.
Also there is a firmware updater from Apple which will upgrade this module; it allows you to use headsets. I now use it to talk via Skype with no problems!
It also is a lot less hassle to install that taking your computer apart …

Lost Bluetooth

My iphone 4S has suddenly lost Bluetooth! It no longer appears on the menu when I go into Settings and I can't get it from the pull up screen although it still has a button, it simply says "Bluetooth not available". Not sure if the recent upgrade is involved but ir is very frustrating as I just bought the BOSE wireless Bluetooth speaker and I can't use it! Anyone come accross this or have any ideas what has happened?

Hi Grandad SE,
If you are having issues with Bluetooth no longer being available, you may find the troubleshooting in the following article helpful (it is for a similar WiFi issue, but the steps should be the same):
iOS: Wi-Fi settings grayed out or dim

HP DV7-3079wm - Does this laptop come with Bluetooth Module installed by default?

Hello all,
I just purchased this laptop and it is enroute to me now via FedEx. I am wondering if the laptop has the BlueTooth module preinstalled by default or do I need to purchase one and install it after I receive it?
Thanks in advance,
~D~

Hello Raven283. I understand that after trying to flash your BIOS from within Windows 8 you're no longer able to boot the notebook. Is this correct?
Here is more information about HP and the upgrade to Windows 8.
It sounds like your thinking is correct. It seems that the installer/flashing program did not properly execute within Windows 8. Now that the flash failed the BIOS does not appear to want to load properly. HP notebooks flash the BIOS via a Windows executable file and do not support flashing via a USB drive. So, you will need to contact HP Technical Support in order to get the notebok back to working condition.
You can check the status of your warranty by going here. Contact HP at 1-800-474-6836 if you're in the US/Canada. If you're in another area you'll need to go to HP's Support Site to get your area's contact information.
I hope this was helpful!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"
