Currently Being ModeratedJul 31, 2007 4:22 PM (in response to Stephan Koepge)Will a replacement be any better than a new logic board?
I wonder if this is CD only, or happens with C2D MacBooks.
I have a CD MacBook, and have the BT problem as well. I currently don't use BT that much, but it's really annoying when it interferes with putting my MB to sleep.CD MacBook, Mac OS X (10.4.10)
Currently Being ModeratedAug 6, 2007 11:31 PM (in response to sfthomas)same problem here...
but it doesnt happen often, 1 month ago my bluetooth went up and down for a few days, and just yesterday it happened again. But today it seemed to be working. By the way, 99% of the time i am using the bluetooth for my Mighty wireless mouse.
when that happens, bluetooth icon dims with a horizontal wavy line across it, when click at it, it says "Bluetooth Not Available", and when i go to the Utilities, the bluetooth section says "No Information found". So, that seems to me the situation is, somehow my Macbook couldnt recognize the Bluetooth module...
my warranty gonna expired in one month.... have to take it in, and hopefully we will have a solutionMacbook, Choose
Currently Being ModeratedAug 7, 2007 9:19 AM (in response to jaychin)This forum thread has been helpful in leading me to a resolution of the same issue, so I want to outline my steps. Hope it helps.
Problem: Bluetooth: Not Available, intermittent, System Profiler information for bluetooth disappears (under USB internal bus info as well...), and Sleep mode is disrupted during episodes.
Steps taken to resolve: Called apple support, updated firmware, performed serveral device checks/repairs, etc, reinstalled OSX from DVD-Rom. Problem remains, support recommended sending it in for hardware repair. Sent to apple, computer serviced and returned (in only 3 days door to door!) and now it works fine, with no more loss of bluetooth functionality, and associated symptoms.
There was not much info about what repairs were made at the service so I called and asked and the best apple could say is that the bluetooth module was replaced.
Its been 4-5 days now without the problem, but based on entries to this thread the problem recurred to some who had a similar repair. I will update if this occurs to me. I informed the apple representative that there are many people with this issue and no 'official' apple support information addressing it. That is the mystery to me.
Good luck everyone.MacBook, Mac OS X (10.4.10)
Currently Being ModeratedAug 7, 2007 1:37 PM (in response to sfthomas)I have intermittently had the BT unavailable problem for a couple of months now (as well as the problem of not being able to sleep my MacBook.)
But after recently installing the 10.4.10 update, I think the problem has almost completely disappeared (I think it only happened once, then solved itself without needing a restart.) It's hard to say for sure since the problem occurs randomly, but so far so good.
Anyone else get similar results?

Currently Being ModeratedAug 13, 2007 7:13 PM (in response to sfthomas)I have a MacBook Pro SR that is about 2 weeks old and have the same problem. Machine boots up and bluetooth is ok for a period of time and then disconnects. I have installed various 3rd party mouse drivers to work with a Logitech mouse I have. Prior to this the problem did not seem to occur however I cant be sure.
I will try an archive and reinstall to see if the problem still happens.iMac G5 20", MBP SR 15", Mac OS X (10.4.10)

Currently Being ModeratedAug 17, 2007 12:37 PM (in response to GwiDan)Hello all,
belive me this issue is a hardware error. I have had the same issue on my old MacBook. And belive me the following repairs haven´t solved the problem:
-> change of bluetooth modul -> after 2-4 days the same issue
-> change of logic board -> error remains direkt
My dealer was not able to solve the issue.
So I call apple support to ask for help but the phone guys told me that they want me to do some more repairs because I have only changed once the logic board. So the denied to take the MacBook back. Trying the next support call with an other guy leads to a contact to an apple technician who was interested in this case. I have send him my System Log where all errors are shown, I send him also some screenplots of the error and I´am send him the repair infos from my dealer. Also I stated that I´am completly feed up with stupid repairs. Every repair makes the Mac Book a little bit weaker because of the assembly/ disassembly . Finaly he agrreed and I have got a actual new MacBook.
Take this info as a hint. Don´t waste time. Bring your MacBook to the dealer for a repair and after 2 tries contact apple and request a new one ! It will be a hard job but take the chance.
PS: I have never heared from somebody who have had sucsess with the repair of the MacBook.
Good Luck to all of you who are suffering with the bluetooth not available error !!!

Currently Being ModeratedAug 19, 2007 11:36 PM (in response to Stephan Koepge)i've been following this thread for a while now, and found another thread that fixed my problem (at least for a couple of hours)
link is here:
but basically, the step i think that did the magic was deleting this file through being root:
" /var/root/Library/Preferences/blued.plist "
the link above describes how to create a root account if you dont have one.
hope it lasts!

Currently Being ModeratedAug 29, 2007 7:49 PM (in response to sfthomas)I wanted to bump up this discussion to get a feel for how many of us are having this problem and if new logic boards/bt modules fixed it at all. I'm still undecided as to whether this is hardware or software, because everything was going fine right up until 10.4.9, and then it got markedly worse with 10.4.10, and I don't think that stupid bt firmware update helped either.
When you look at it like that, it's gotta be software, but the way it turns off and on, and makes bluetooth unreliable and how the hardware profile won't even see it and how all these little bug fixes for me don't work for anymore than five minutes at time... make me think it's hardware.
I just don't want to get on the repair treadmill if Apple has the attitude of "we haven't listened to a single complaint" and want to no nothing about it, and so you do the repair cycle shuffle with nothing solved because it was never hardware to begin with.
So, anyone really have a hardware fix solve the problem 100% for sure?Black Macbook, Mac OS X (10.4.10), flakey bluetooth
Currently Being ModeratedAug 31, 2007 2:49 AM (in response to sfthomas)Hi.
I also own a 1st gen MBP and suffer from unreliable bluetooth functionality from the beginning.
During the last year I had 2 logic boards and 3 bluetooth modules and SATA cables replaced by Apple - with no success. Sometimes bluetooth is working as expected, somtimes it shows the well mentioned "Bluetooth: not available".
I too have no idea if this trouble is caused by faulty hardware or if it's a software problem. If it is hardware related, then Apple should consider buying bluetooth modules of better quality, as the faulty behaviour apears also after exchange of parts. Maybe it's a problem with the cable connection, as the bluetooth module is somehow placed loose next to the harddrive, so the contacts may shorten or disconnect. I recognized this after opening the MBP (mine is out of warranty, meanwhile).
I tried all the hints given on this forum and anywhere else. None of them worked durable in the end. Deleting certain .plist files, zapping PRAM and SRAM, all this to no durable effort. And I don't think that the version of OS X matters, as I encountered this behavior from 10.4.4 to 10.4.10.
Anyway, the bluetooth issue is getting on my nerves. You never know if it's working or not. And it certainly may fail just in the moment that you need it. During the last couple of days it kept working - but you need to develop some kind of fatalism to get along with it :-/
I hope this helps.

Currently Being ModeratedSep 1, 2007 2:37 PM (in response to sfthomas)Running the same problem ...
but the last trick proposed in this forum did the job!!
READ THIS POST FULLY BEFORE EXECUTING COMMANDS.
Simply open terminal and do:
Of course, replace [yourrootpassword] by your real root password, created at first OS install, good chance it's the same password than your main account.
Don't forget that "Library" is not equivalent to "library", capitals are important on Linux-like OSes.
Don't worry for blued.plist file, it's recreated automatically.
If you want to compare old and new blued.plist file simple do
cp blued.plist blued.plist0
BEFORE removing the blued.plist file above
Might be a file that didn't like the numerous updates.

Currently Being ModeratedSep 4, 2007 9:16 PM (in response to vocamen)Nope, that doesn't work and never has on my black macbook. BT just seems to have a mind of its own. I know how this is going to work - I'll call Apple and here in Finland they are very nice and quick to offer an appointment down at the service center, and they'll say they've never heard of this widely doccumented problem, and I'll have to wait a few weeks because there's a run on logic boards, and then after that, it may or may not work.
Come on Apple. Is Bluetooth too difficult for you?g4/800 15 iMac
Currently Being ModeratedSep 8, 2007 7:02 AM (in response to Anders Ruohio)Hey Anders,
Once again, I ran in the same problem after a reboot ... grrrr
So I gave a last change to the full test proposed in another post:
unplugged all USB
repaired disk permissions
deleted 2 BT prefs files
reseted power management
removed the 2 BT prefs files, once again
BT didn't work ... grrr
until I re-plugged my USB printer!!!
BT is back! and is running (even if it was on OFF position before)
But for how long?
Can someone test the same protocol and post back results?
It reminds me the old mysterious procedures to have appletalk back again on some mac os 7 (yeah, I'm that old).

Currently Being ModeratedSep 10, 2007 4:22 AM (in response to vocamen)I don't usually keep usb devices plugged in, but it's not affected bt coming back. Repairing permissions and resetting the SMC are short-term fixes for me. In fact, I don't think it does squat anything, because shutting down the computer may or may not have the same affect, the same way as all of these fixes may or may not have the same affect.
In fact, things have gotten worse. Usually if I just keep bt turned off, I can hibernate my macbook whenever I like... but that's changing in the past few days. Sometimes with bt not even on, I'll still get "bluetooth not available" with all the problems it brings with it.
