Snow Leopard and Bluetooth problem

I just installed Snow Leopard and my problems are starting. I have a 3 months old MacBook, so the hardware should be no problem. I used a LCD display and had a Mouse and a Keyboard wireless. Since installing Snow LEopard there is no more bluetooth and there is no info in the system profiler. How can it disapear from one day to the next with installation of Snow Leopard. it sounds like a bug. Can someone help?

macbook, Mac OS X (10.6), airport disk, hard drive, PCs, Nikon camera, Aperture

Apple can add another person that no longer has any Bluetooth.

I had it on 10.6 but not 10.6.1 - none of the suggested solutions work.

Does Apple even read these posts?
Bluethooth is visible in the top menu bar but says "Bluetooth not available"
In the System Profiler Hardware is says "No information found."

Resetting the PMU and the PRAM solves it temporarily. I have a suspicion that it has something to do with the power management unit (PMU). The machine now sometimes goes into a sleep-wakeup cycle when you close the lid. For the time being I installed iLid prefpane and disabled wake-on-lid-open.

The bluetooth isn't really used, so suppressing the other PMU symptom should be enough for now.

with me, the issue is a bit different, but still BT probs with SL.
Already two kernel panics, both times in the bug report BT was mentioned.
the second kernel panic happened, when I simply changed the battery of my mighty BT mouse.
Now, after wake up of deep sleep: no reaction of BT, could not de or activate it, had to restart.

Ok, not that bad like other problems, but still very buggy and annoying.

Hi
I had same problem, installed SL and the bluetooth was just gone. So i called apple and this is how they fixed my problem. This is my first time posting and hopefully i am allowed to put it here.
1. Hold power button down and turn your computer off
2. Turn your mighty mouse off and take the batteries out, (if you have fresh ones, replace them)
3. Put the batteries back in but DO NOT turn the mouse on
4. Hold control and shift keys on the right side of your keyboard and turn your computer on by hitting the power button once, once you turned it on, release the control and shift keys
5. Turn your mouse on
6. Once your computer is back on, move around the mouse and go to system pref and the bluetooth icon should be there
This worked for me, hopefully it will for everyone else.
Thank you DRkoh

I tried the whole shebam with all the resets of PMU, PRAM, Bluetooth plists, PowerManagement.plist, and sleepimage removal. Didn't help.

Today removed /Library/StartupItems/ArcanaStartupSound, /Library/Preferences/arcana.StartupSound.plist and /Library/PreferencePanes/ArcanaStartupSound.prefPane

Rebooted, had no problem in 10 sleeps. Reinstalled StartupSound.prefpane v1.1, still no problem.

Maybe some system wide cache is corrupt, for which a refresh is triggered when removing the startupitem or the prefpane. I am still testing though.
