Welcome to Lenovo Community Forums!
I’m sorry to hear that you had difficulties to turn on Bluetooth in your Lenovo ThinkPad T520.
Ensure that Hardware switch to enable wireless connections has been turned on.
Go to BIOS -> Security ->I/O port access ->Check if Bluetooth is enabled.
Tap FN + F5 and enable Bluetooth radio.
Now check if you can find Bluetooth radios in device manager.
Hope this helps!

Nice to hear that Bluetooth started working now.
Try updating your power manager and power management driver as well and check if FN+F5 shows up wireless connections window.

I had the same problem. I installed the hotkey integration features and Lenovo Access connections and now get the window when I press FN+F5 but I have no idea what to set/click on, enable etc to connect to a bluetooth speaker that is flashing - can someone explain EXACTLY what I need to do. The device was picked up and appears when I use the blue "B" Bluetooth icon from the popup from the right of taskbar and "Show Bluetooth Devices" but I don;t know how to getthe devices to pair - it was really simple with my sony Android tablet and my Sony mobile phone to connect to this speaker but I've spent hours on this today to try and get the my T520 connected and I've got nowhere - why the hell is isit so much more complicated with Windows 7 Pro/Lenovo?

I ordered the Bluetooth card off of Amazon and during the installation, found that it already had a Bluetooth card installed in my 4239 machine - this was after updating, checking bios for Bluetooth and Clt+Fn5 did not work.
The solution for this machine was to update to the latest bios and the hardware was recognized immediately.
