W520 Bluetooth radio seems to have vanished...

2013-01-02, 1:49 AM

Not long ago, I had working Bluetooth on my W520-4282.

Recently, I attempted to make use of my Bluetooth radio, only to not find it in the Fn+F5 menu. I attempted finding it in the Device Manager, only to find it missing. I can't use any Bluetooth functionality nor can I find a way to activate it. I believe this to mainly be a problem with my Bluetooth functionality being “Soft-locked” by Lenovo software.



  • No Bluetooth in Device Manager
  • No Bluetooth radio in Fn+F5



I've tried the following:

  • Reinstall Bluetooth drivers
  • --Can’t accomplish this because the Bluetooth device cannot be found
  • Setting the option for I/O Bluetooth functionality in BIOS
  • --Already set to Enabled
  • --Tried toggling it to Disabled then back to Enabled
  • Updating the BIOS
  • Updating Power Manager / Power Manager Driver
  • Updating the Hotkey drivers
  • Enabling the “Bluetooth AMP” in the Intel Centrino Ultimate-N 6300 AGN (My Wi-Fi card) properties menu (Advanced Tab)
  • Disabling and Enabling my Wi-Fi adapter
  • Completly uninstalled and reinstalled my Wi-Fi card


Please, not many people seem to be having this problem, but it’s driving me nuts.

Hi, MicAns


What's the behavior of the Bluetooth LED during this time, if any? Also, if you click Start and type msinfo32 into the search box and hit Enter, a window will appear. This window is similar to Device Manager, but much more detailed. There should be a search box at the bottom. You can type Bluetooth in the search box and scroll through everything pertaining to it, or use the tree in the left panel. Eventually, you should come to a page where you can find the adapter of the Bluetooth and its status. 


Good luck, and let me know what you find
