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!
