T420s Bluetooth suddenly not found

Hi all,

 

My T420s suddently cannot find built-in Bluetooth device. When I clicked Fn+F5, there is no Bluetooth option anymore. I tried to enable Bluetooth in BIOS's, but it doesn't work at all. I also tried to reinstall the driver, however, it said it cannot find the Bluetooth device. Please help me out to get my Bluetooth device back.

 

Thanks A LOT!

Check if the hardware switch is turned on.

In BIOS -> I/O ports, no Bluetooth?

I have checked the BIOS and Bluetooth is "Switched On". I have tried to reinstall the driver and it ends saying that there is no Bluetooth Device
