In Lenovo laptop device manager shows” bluetoothBus Enumerator “ .in laptop taskbar we see Bluetooth panel but some time it will be hidden. so by pressing Fn+f5 you are able to see this panel and just try to install latest updates and drivers of the Bluetooth from internet which can resolved compatible issued. 6.2.1.3100 is the most recent one for a T400. I checked, the wireless switch is on or not if not then make it on.
