Windows 7: No Bluetooth devices found

Windows 7 64bit
 
 

Me too, I've got the same problem as the above three posts. I'm running Win 7 on 64bit, on a Sony Vaio VPCF116FGI. Until yesterday I was successful connecting to my Logitech blue tooth (M555b), but now no longer. When I try to add bt device it just goes into an endless search. I have set bt services to automatic, but to no avail.
I'm currently installing the SP1, hopefully this might help, any ideas appreciated.

Windows 7 Professional 32-bit SP1
 
 

Dell Precision M4400 Win 7 Professional 32 bit SP1 here. I'm having the same issues with my Dell 370 Bluetooth internal card. Enabled in BIOS, I've tried every WIDCOMM driver available, let Dell VPN into my computer to try to fix it (twice), service set to Auto, deleting bluetooth registry values, and nothing has worked. Dell recommended a complete reinstallation of Windows. I'd consider it if it was an option for me (company laptop).

I initially installed the official (read: outdated) drivers from the Dell website, and I was able to connect my Microsoft 5000 BT mouse as well as connect my Android phones. After the first reboot, I haven't been able to find the bluetooth devices. Bluetooth works every time when I boot into Ubuntu on the same laptop, so it's not a hardware issue.

Thanks in advance for any insight!!!!!!

Same here, pretty much exactly as MTIP described, same hardware.
Can anyone shed any light on this?

If your Bluetooth Mouse quits working after a Windows 7 update, try the following.

Go into Control Panel -> Device and Printers and see if there is a mouse (or 2) already there. If so, right click on the mouse picture and Remove it. Repeat for all of the phantom mice.

Reboot and try the discovery process again.

Works on Vista also.

same prbm with 2 laptops...

Hi folks,
After installing Win updates, i get the same symptoms as described above in my two laptops, one a XP-x32, the other a Win7-x64, both were happily connecting to and using my bluetooth mobile phone before the Win updates.

The XP-x32 was cured after changing the BluetoothService to log on using Local Account and changing it to run in Automatic Mode.

The same trick did nothing for the Win7-x64.

Both machines are using the same bluetooth dongle, so no hardware issues with the dongle.

No phantom mice on the device manager, only a Synaptics Touchpad, deleting it and rebooting had no effect.

In fact, after going through the device manager and systematically deleting all bluetooth devices (bluetooth HID device, bluetooth modem, bluetooth RFCOMM protocol, bluetooth PAN, etc.), and during the reboot, i noticed the system automatically reinstalled all the deleted devices even before i try to search for and install the bluetooth phone, and nothing is found when i try to add the bluetooth mobile phone...

Any of your gurus have an opinion on this?

Yours very perplexed.

Hello! Ive experienced the same problem with Dell Vostro W7 x64 for months... today an automatic software update solved the problem and all my devices started working correctly!

Exact same problem here. It started when I tried to solve my bluetooth mouse problem by changing my bluetooth support service logon as to Local System Account. After changing back to logon as Local Service, everything is fine.

Just in case you can't figure out how to do it, here's how:

Click start and type service, the Services should be highlighted. Just click it. Double click Bluetooth Support Service, click Logon tab. Select Logon as This Account, type Local Service, enter your admin password and hit ok. You'll be prompted to restart the service, just restart it.

I keep saying this... but checking the Bluetooth Service is running is of paramount importance - by default it seems to be set to manual start, and not automatic - thus crippling BT devices of course...
Thank you for this, you don't know how long I tried to get this too work, I had to make an account and thank you.

Thank you so much! I had done the exact same thing as you (my bluetooth mouse was laggy and sometimes wasn't pairing, so I found a link that said to change it to Local System Account). I completely forgot I changed that and once I rebooted, my bluetooth completely stopped working (as described in this thread).
I ended up Googling everything I could think of, and I tried resintalling every related driver. Finally, this thread fixed it!

One thing to note for future readers: I had changed every service related to Bluetooth, so if just changing the "Bluetooth Support Service" doesn't work, make sure every other Bluetooth service is also changed back. For me, I had two services ("Bluetooth Support Service" and "Bluetooth Service") that I had to change for it to work again.

Brilliant worked for me too. Now I can once again harness the delight of my bluetooth devices
