B50-80 - NO BLUETOOTH CONNECTION in WIN7 x64

I can't get any bluetooth connection ( Phone, mouse, printer, .. ) to my B50-80 under Windows 7 x64. All device drivers are installed from the Lenovo support page and no device is marked as inoperable in the device manager.

 

Hope anyone has a hint or solution.

 

regards

Hi!

 

Did you solve your problem?

 

By the way, which is the precise product number of your B50-80?

 

I have a B50-80 too, maybe we have the very same device.

Hi kuno21!

Thank you for your reply.

 

My full product number is 80EW 0192IX so we might have the very same laptop.

 

In device manage i see two devices/entries under bluethooth.

 

1) microsoft bluethooth enumerator (ID hardware BTH\MS_BTHBRB )

2) Inter (R) Wireless Bluetooth(R) 4.0 (ID hardware USB\VID_8087&PID_07DC&REV_0001  and  USB\VID_8087&PID_07DC ).

 

Do you have the same specs?

Well, thank you for posting those screenshots!

The microsoft device (with driver versione number 6.1.7601.17889 ) is the same as me.

 

The other one it's different. The hardware id (hardwarekennung) is different ...

Mine is

USB\VID_8087&PID_07DC&REV_0001

USB\VID_8087&PID_07DC

 

Yours is

USB\VID_0BDA&PID_B728&REV_0200

 

Could you check just another thing? If you really installed the intel driver also you should find this folder:

 

Computer-->Local Disk C-->drivers-->Intel Bluetooth Driver

Re: B50-80 - NO BLUETOOTH CONNECTION in WIN7 x64

the folder :  Computer-->Local Disk C-->drivers-->Intel Bluetooth Driver

is only the place wher the downloaded driver-files are extracted to, so windows can find the drivers.

 

In the drivers folder i have all downloadable files extracted.

 

In "Control Panel -> Programs & Features" there is only REALTEK BLUETOOTH DRIVER listed.

Intel Bluetooth Driver is not listed there. So it shouldnt be installed

 

PID&VID  Driver identifier.com

 

you got Intel hardware

Device Name
Intel(R) Wireless Bluetooth(R) 4.0 + HS Adapter
Hardware ID
USB\VID_8087&PID_07DC&REV_0001
USB\VID_8087&PID_07DC <---- Device ID matches with our database

 

 

 

i got realtek hardware

Device Name
Realtek Bluetooth 4.0 + High Speed Chip
Hardware ID
USB\VID_0BDA&PID_B728&REV_0200

Re: B50-80 - NO BLUETOOTH CONNECTION in WIN7 x64

Thanks for this usfull information.

 

So it really seems that we have a different bluetooth adapter. It seems reasonable since there are several hardware configuration of the Lenovo B50-80.

 

My full product number is 80EW 0192IX.

Even though the first 4 digit of your product number are the same, the last 6 digits are probably different.

So we don't have the VERY SAME device.

 

:-)
