I did "Dell Update" in order to have update for drivers. One of updates was for Bluetooth and now I can't turn it on anymore. There is even no Bluetooth section in "Device Manager" and I tried to do "Scan for hardware changes" in "Device manager" but nothing happened. Of course I restarted laptop several times but that did not have any effect. Also windows has last version. Can you please help me?
I assume no devices in device manager with ! or ? next to them ?
Airplane mode is off?
Have you tried downloading the drivers manually from the dell support site for bluetooth and installing them manually?
