Bluetooth not shwoing up

Have a Dell D420 with Bluetooth enabled onboard. I've installed the bluez-utils and -libs (versions 3.12-1), started dbus and then bluetooth. Out put from dmesg shows:
iain@expat-d420 ~ $ dmesg | grep -i blue
Bluetooth: Core ver 2.11
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: L2CAP ver 2.8
Bluetooth: L2CAP socket layer initialized
Bluetooth: HIDP (Human Interface Emulation) ver 1.2
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: RFCOMM ver 1.8
When I run hciconfig I get nothing back:
iain@expat-d420 ~ $ sudo hciconfig -a
iain@expat-d420 ~ $
Modules seem to be laoded up just fine:
iain@expat-d420 ~ $ lsmod | grep -i blue
bluetooth 46820 5 rfcomm,hidp,l2cap
Nothing in the wiki to point out how to get this working correctly, only BT mouse and headset. any pointers to how I can get this working correctly?
Iain.

Hmm, the problem here, it would seem, is that the device is not getting created. In any case, here's the result of that command:
iain@expat-d420 ~ $ sudo hciconfig hci0 reset
Can't get device info: No such device

IMac takes 4 minutes to boot up, bluetooth not available

Hello, this is my first post on Apple Discussions!
The day before yesterday we had quite a vicious storm here and lost power for about a minute. My Mac was switched on when the power cut out, but I was downstairs, having some lunch. Unfortunately, I have no surge protection on my power bar / extension cord thing (I know...). I immediately unplugged it, only turning it back on after the storm had calmed down.
Thinking nothing of it, I powered on my Mac and left it unattended for about 10 minutes (so I don't know how long it took to boot up!). When I came back, I was greeted by the login screen and proceeded as usual. However, the next time I powered on my computer, I could not get past the white screen after the chime (no Apple logo). Now, this has happened to me before, so I waited a couple of minutes. Nothing. I decided to power it down (holding down the power button) and try rebooting it, this time holding down the option key (to bring up the partitions), as this has helped me in the past. White screen for a couple of minutes. Impatient and annoyed, I powered it down again. Rebooted holding down the shift key, for Safe Mode. Nothing again. This time I left it on the white screen while I looked for an old USB keyboard, thinking my wireless keyboard might not have been pairing. Little did I know I would have to use this sh***y keyboard from this point forward.
So, I got my keyboard (remember I had left my Mac on the white screen) and when I returned I was pleasantly surprised to see the login screen. I noticed, however, that I could not use my wireless keyboard (I have a wired Razer mouse). So I plugged in the old PC keyboard I found, and logged in. Which is when I noticed the Bluetooth icon was strange; it was greyed out and had a jagged line through it, and when I clicked on it, said "Bluetooth: Not Available".
I restarted my Mac, just to see if the issues would be fixed. Nope. It took about four minutes to start up, and no Bluetooth. I checked the System Preferences and it says there is "No Bluetooth Hardware Found". "No information found" in System Information either.
The problem is that during the white screen on bootup (I always hear the chime btw), I have no control. I cannot enter Safe Mode, see the partitions, reset the NVRAM or PRAM. I just have to wait until I see the Apple logo after about four minutes. After login, everything (bar Bluetooth) seems fine. I have verified disk, and it says it's fine. Verified and repaired permissions as well. I looked and noticed that I have no com.apple.bluetooth.plist file in my library.
I don't know what to do from here! My extended Apple Care has expired Should I install Mavericks? Could that fix my problems? Or should I clean install ML, and then install Mavericks? But if the storm did do some damage, the issue is probably hardware... Please help me.
Thanks, and sorry for the length
PS. I have been having a little trouble with my finder since a while now (months). Sometimes, when I open a folder the CPU will shoot up to 100% and the Mac would freeze for a couple of seconds. Then it would be normal again. I have used up about 1.5 TB (including a Bootcamp partition) from my 2TB HDD. I doubt this is related, but I though I'd throw it in anyway. Again, I apologise for the length.

Installing a new OS X over a problematic one will get you a new problematic OS X.
I suggest you run repair disk first. Then I would reset the SMC.
I "think" that some of your problems stem from the power problem you described. No surge protector is akin to (fill in the negative outcome blank). The lecture ends here.
IMHO, you have some hardware problem(s). I suggest you take the computer to an Apple store for diagnosis. Be sure to bring your documentation of the things above along.

In ios7 Bluetooth not working with my ipod touch 5G

In ios 7 upgrade bluetooth not working properly... It's always searching ... not detecting even ipad with ios7 (bluetooth on).
I was expected 7.0.3. but no use...

Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset the BT device
- Reset network settings: Settings>General>Reset>Reset Network Settings
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Bluetooth not available MacBook Pro (13-inch, Late 2011) Yosemite

Hi guys, I've been having a problem lately and I can't find a fix for it. My problem is my bluetooth button on the top menu bar had a black squiggly line through it then when I click on it, it says "Bluetooth: Not Available". When I go to system preferences the tab for bluetooth isn't even there its just gone all there is is network. I am trying to connect my magic mouse which has worked fine until now, I had this problem in Mavericks and upgraded to Yosemite to see if that would fix it, Also please note I have tried Resetting PRAM, Deleting the bluetooth files, and Force-quitting "blued" which didn't do anything.

Well then, unfortunately for you, the conclusion becomes clear: your BlueTooth isn't working correctly anymore.
You can try reinstalling OS X from the Recovery Partition - boot your computer with the [cmd] + [r] keys pressed until you see a Utilities window - but since upgrading from Mavericks to Yosemite pretty much amounts to a reinstall anyway I am not giving it much of a chance at success. Still, won't hurt though. Contact AppleCare for warranty options.

"Bluetooth: Not Available" after upgrading to Yosemite

Hello everyone,
I just upgraded my MacBook Pro (15" with retina) to Yosemite this morning, and could not use my wireless trackpad correctly anymore (i can't scroll or swipe)
The bluetooth icon in status bar is grey and says "Bluetooth: Not Available"
The weird thing is, i'm still using my wireless keyboard and trackpad (i can move the pointer and left-click).
So the bluetooth module is somehow still working.
I tried deleting the "com.apple.bluetooth.plist" file, and the SMC reset "fix".
But it is still .. it remains "not available".
Any ideas ?

Hey there CesarD,
It sounds like your wireless keyboard and trackpad do seem to be working but for some reason the bluetooth icon is grey and you get a message saying that bluetooth is unavailable, even after deleting the bluetooth plist file, and resetting the SMC. I would next do these steps from the following article found here:
OS X: Bluetooth devices become unresponsive
Shut down your Mac, disconnect all USB devices for two minutes, start up, and re-connect your USB devices once again.
If the issue persists, I would next reset your PRAM for good measure:
OS X Mavericks: Reset your computer’s PRAM
Thank you for using Apple Support Communities.
Take care,
Sterling

Bluetooth not available after upgrading to Mountain Lion

Mine is a mid-2011 iMac. I tried all the ways listed in https://discussions.apple.com/message/4874277?messageID=4874277#4874277?messageI D=4874277 but with no luck.
Anyone experienced similar issue with a solution?
Thanks.
Wenbin

Yes, I'm having the exact same problem.
1. Bluetooth not available from the menu option "Bluetooth: Not Available"
2. Yet, my Bluetooth Apple Magic Mouse works as a basic mouse
3. None of my gestures on magic mouse work (scrolling, swiping, etc.)
4. My Apple Bluetooth wireless keyboard works, but the iTunes control from F7 to F12 no longer work as the pictures imply (e.g. F12 should be volume increase, but it goes to Dashboard)
Reboot doesn't fix it. Haven't try safe mode.
APPLE, PLEASE HELP.

"Bluetooth: Not Available" problem created by software update; need help please?

I ran a regular software update as prompted by my iMac to get to 10.6.8, and now have "Bluetooth: Not Available" with squiggly line thru it. I've tried an SMC, updated software to 10.8.4...no availability of my Bluetooth to work the magic mouse, or any ability to access Bluetooth in System Preferences...help please?

You say you have "tried an SMC." Reset the SMC nd PRAM again.
Barry
P.S. It is unlikely that the update had anything to do with the missing Bluetooth.

Bluetooth not available error

I got a early 2008 MAC PRO with additional wireless keyboard and mighty mouse few weeks ago.
Recently I keep encountering the "bluetooth not available" problem after software update (system reboot) if I have USB devices attached to the MAC PRO. Also, if I connect the Logitech quickcam ultravision directly to the MAC PRO, the bluetooth will have "not available" error after system reboot. If I connect the quickcam to the USB HUB, the problem won't happen.
This error happened again when I install the new Safari update while I have the keyspan USB-to-Serial connected to the MAC PRO.
I have all the latest updates installed in my MAC PRO. I don't know what happened, but I hope this problem can be fixed so that I don't have to keep unplugged all my USB equipment if I need to reboot my MAC PRO.

Hi there,
I just had the exact same thing happen! I had my usb 2 flash stick and MyBook 320HD only. I then noticed that the MyBook wouldn't sleep even though the Mac was shut down. I had to force shut off the drive by removing the power lead. I restarted the Mac with no usb whatsoever and voila! All is now ok.. I wonder if this is connected with the motherboard power management??

'Bluetooth not available' error message since upgrading to Leopard

Hi, I regularly seem to get a 'Bluetooth not available' error message since upgrading to Leopard, any ideas why, have to reboot to shake it.
cheers
Simon

I solved the same issue by resetting the SMC. With the computer off, remove the battery and press and hold the power button for 5 seconds. Then reinstall the battery and restart. I haven't had any bluetooth issues since.

Bluetooth not functioning correctly.

Bluetooth not functioning correctly. I have version 10.10.2. How can I get it to connect and be stable?

OK. Spooky. Minutes.... Minutes after I posted, my Mac connected...
