I HAVE A BRAND NEW LENOVO B500 IDEACENTRE ALL IN ONE PC WITH A WIRELESS KEYBOARD AND MOUSE. SOME TIMES THEY WILL NOT WORK AND LENOVO TECH IS COFUSED AS TO WHY , BUT THEY TAKER OVER MY PC AND FINNALLY GET BLUETOOTH TO RECONIZE THE KEYBOARD AND MOUSE THEY WILL WORK FOR AWILE AND THEN STOP WORKING .
I ALSO GET A MESSAGE ON START UP THAT SAYS UNABLE TO START UP BLUETOOTH STACK SERVICE. I TOLD THAT TO TECH SUPPORT AND THEY DID NOT KNOW WHAT THAT WAS. ANY REAL HELP WITH THIS WOULD BE APPRCIATED.
1. Joe, please delete your email address from your post.
2. Check your Device Manager for a badly installed device.

Its registration issue.
If you are still receiving : ERROR: Unable to start Bluetooth Stack Services?
Have you recently run a registry program for example Registry Booster 2?
If so then this may be the cause and suggest you restore to an earlier saved point from the RB backup.
I had the same issue and despite contacting Dell support and checking internet forums, the problem still occurred until I recognized it was the registry program new settings that was causing the start up problem.
I restored on the Registry problem to the back up and the issue has gone. I can even locate my BT TRAY.
Microsoft support don't seem to have an idea. Nothing new there.
You may well be correct, however there is a major problem: I have NEVER been able to Restore to an earlier version in Windows 7. I did so several times with XP over 4 years, but W7 just won't let me. I've disabled the firewall, disabled virus control, I don't know if it's something to do with ZoneAlarm, but as I say I've disabled it; but it makes no difference. Once again, after many attempts W7 WILL NOT RESTORE. So we need a cleverer fix than you or anyone else has so far mentioned.
