    You may not care about bluetooth but I'm sure you care about suspension to ram (aka sleep functionality). Yes, the bluetooth problem kills suspension too.
    I don't want to waste my time with Apple any longer, I'm selling my 2ghz Core2 Duo white MacBook, 1GB RAM, 80GB hd, under warranty until November 16 for 700€. Anyone interested?

    I have the same problem. Yesterday I was thinking if maybe it appears when the CPU ist working hard. Does anybody know a way to make the CPU run at 100% without running any special programs? Like that I would bei able to demonstrate the problem to the local ASP-guys...

    Open two terminals and run "cat /dev/urandom > /dev/null" on each.

    I just came back from the Apple Store. Took a little over a week but they called me today informing me that my new MacBook came in. I now have a brand new macbook due to them unable to fix my previous macbook.

    It seemed to happen to me when:

    *1. The adapter was plugged in and the battery was fully charged.*

    *You can have CPU intense programs running, surfing the web, or even having the screensaver on, if I had the laptop plugged in, the bluetooth and sleeping problems would occur.*

    Whenever I would go in to the Apple Store to show them the problem, it wold be gone and everything would be normal. Of course, because it wasnt plugged in. It happened to me a few times when I went in to show them.

    The first time, it took ~20 minutes NOT plugged with CPU-intense programs running to have the problem occur. They replaced the Logic Board, a cable, and a bluetooth module. (Back in May 07)

    The second time (Sept 22) they could not reproduce the problem. They took it in to test it. Come back friday (28th) with them only telling me there was nothing wrong with it.

    The 3rd time (Sept 29) I had videotaped the same problems occuring the SAME night I received back. I showed them the video and they acknoledged that there definately something wrong with my laptop and offered a replacement

    Now October 9, I now have a brand new Macbook (with upgraded processor and hard drive).

    Just wanted to add my voice has having this problem. I don't use BT much, but I used to go weeks without halting my machine, and now I can't put it to sleep or else it wakes itself up and spins its fans like crazy. And now it's out of warranty... I've reset the PRAM, reinstalled the OS (from scratch!), applied all the firmware updates... nothing seems to work.

    Please read the post labeled "bluetooth hardware problem - resolved".

    There are people in that thread who have fixed the problem.

    I followed the instructions and took my macbook apart and rerouted some cables (because there was interference) and I have not had a bluetooth or sleep problem since (4 days and counting).

    HOPE THIS HELPS!!! I SAW A TON OF PEOPLE WITH THIS PROBLEM!

    Didn't work for me. There wasn't a bluetooth file in the root library, but was one in my user library. Deleted it, rebooted and same thing. Already reset the pram and power management system.

    I can live without the bluetooth. It's the fact that the computer wont sleep that is the problem for me.

    Warrenty expired 2 months ago so I'm keeping my fingers crossed someone will find a solution.

    Same problem here. I have tried reseting, reinstaling the 10.4.10 directly, and no luck.

    Bluethooth ; not available is intermitent, and when off, the MB won't go to sleep when lowering the lid.

    I now have turned off Bluetooth, and the machine goes to sleep , but of course I miss the conection with my cell phone.

    Will take it to the mac representative, though I see it won't be easy for them to find a solution....

    I cannot believe that Apple does not know about this issue. A quick google search for "Bluetooth: Not Available" results in thousands of posts on this topic.

    I have had my MacBook Pro 17" Intel now for 4 months and it has been flawless. I recently updated to Leopard and that is when I got my first taste of the faulty Bluetooth configuration. My Logitech v270 and wireless mighty mouse go offline/online along with the Bluetooth interface. After following the recommended steps by a number of posts to no avail, I finally just disabled Bluetooth and resorted to using a wired USB mouse.

    By the way, my kids new iMacs work fine with their wireless Bluetooth keyboards and mice even after the Leopard update so something that my MacBook Pro doesn't like.

    I have heard that this must be a hardware issue because it happens with Windows as well, but I am thinking that it was triggered by a software update and in my case, that came with Leopard. Or maybe it was a coincidence that mine worked flawlessly and broke after Leopard.

    I am very hesitant to give the $2,600 laptop to Apple so they can replace the logic board, reset stuff, and only to have it happen again. I have heard about this happening in other posts. Until Apple says that they know about the issue and have a sure fire fix, I am not ready to depart with my Mac for "let's try this to see if it fixes it" experiments.

    I hope this issue gets resolved by Apple as I will be sure to want to use the Bluetooth interface for additional devices in the future.

    Cheers,
