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!

Re: T420s Bluetooth suddenly not found

Check if the hardware switch is turned on.

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

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

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
