Lenovo T400 Windows 10 Bluetooth not working

Hey guys!

 

My colleague & I recently purchased 2 Lenovo Thinkpad t400's with windows 10. Both laptops were supposed to be equipped with bluetooth. However, my laptop doesn't seem to have the bluetooth connectivity option available, while my colleague does! I have tried following the answers suggested in this post: 

https://forums.lenovo.com/t5/user/VerifyUserEmailPage/user-id/1235911/mail-message-tracking/J02S5C8U...

 

but still no luck.

 

Any help would be great. Thanks in advance!

 

PS I know the laptop has the bluetooth option because the small dash under the screen has the indicator for bluetooth but does not light up.

Hi friend, 

 

Welcome to Lenovo Community! And happy to have you here.

 

As I understand that you are facing issue with Bluetooth which is not working in your T400.

Just to confirm can you share me the snaps of Device Manager whether Bluetooth device is getting detected or not.

 

Please let me know the above requested detail to help you.

And feel free to post in Lenovo Community Forums if you have any further queries!

 
Cheers,

Prabhansh

Hi Livelong, 

 

Thanks for the snap, as per it there is no Bluetooth device being detected in Device Manager

So kindly check in BIOS menu under Security>I/O Port Access>Bluetooth whether it is Enabled or Disabled 

 

I hope the above information helped you.

And feel free to post in Lenovo Community Forums if you have any further queries!

 
Cheers,

Prabhansh

Hey,

 

I entered the system through BIOS to find that the bluetooth was already enabled. After disabling and restarting then enabling and restarting again, I still cannot find the bluetooth in the device manager.

 

 

Thanks again

Hi again, 

 

If that's the case, you check in Device Manager under View> Show Hidden Devices & look for any hardware changes or Bluetooth is getting refelected or not.

 

Do update us how it goes.

 

Cheers,

Prabhansh

Go here: https://support.lenovo.com/us/en/solutions/pd012419 Try removing and reseating the bluetooth card. If that doesn't work, buy a new card on eBay

And we're back...
