I double-checked that Bluetooth is Enabled in the BIOS of my Lenovo Thinkpad. Still it is invisible in Windows:

  • Device manager doesn't have any "Bluetooth device" (I also checked with "Show hidden devices)
  • Services: I checked that all Bluetooth services are in Automatic and Started in Windows
  • I have done FN+F5 but still the laptop's Bluetooth LED isn't green (near the Wifi green LED)
  • I am sure that the laptop is equipped of a BT adapter
  • I have installed the latest Lenovo Thinkpad drivers for Bluetooth
  • I have tried to go to Setup, disable BT in the BIOS, boot Windows, reboot to Setup, re-enable BT in the BIOS, boot Windows with the hope it will see a "New device" - not working
  • I have tried nirsoft's tool BluetoothCL.exe, and it shows nothing

I know that BT worked in previous Windows installations, so what are the last solutions that could be tested to finally restore Bluetooth on a Lenovo Laptop with Windows?

PS: I spent more than one hour on this, so now I found the solution I share it with "Answer your own question" feature!

Strangely, it seems I had tried everything, but this was the only solution that worked:

  • Reboot on Linux (even with a Live CD, for example Ubuntu)
  • Enable Bluetooth there (FN+F5) and try that it works
  • Reboot to Windows
  • Bluetooth is permanently restored!
