Something strange has happened to my Lenovo IdeaPad 310 with Windows 10 latest updates.
My Bluetooth headset was working fine. But now the toggle to switch Bluetooth on/off has gone missing.
Settings > Bluetooth and other devices
Bluetooth on/off toggle is missing
Settings > Bluetooth and other devices > Senheiser MB Pro 2
Bluetooth is turned off
My headset is listed as a Bluetooth device but the buttons "Connect" and "Remove device" are both disabled.
Device Manager > View > Show hidden devices
The Bluetooth section contains four entries :
Bluetooth Device (RFCOMM Protocol TDI)
Microsoft Bluetooth Enumerator
Microsoft Bluetooth LE Enumerator
Qualcomm Atheros QCA9377 Bluetooth 4.1
All have a faded blue Bluetooth icon.
Right-click on any of them has the same message :
Currently this hardware device is not connected to the computer ( Cede 45 ). To fix this problem, reconnect the hardware device to the computer.
Right-click any of them and select "Update driver" :
The best drivers for your device are already installed.
Windows has determined that the best driver for this device is already installed. There may be better drivers on Windows Update or on the device manufacturer's website.
Troubleshoot > Bluetooth > Run the troubleshooter
Device does not have Bluetooth
Bluetooth is not available on this device. Please try using an external adapter to add Bluetooth capability to this computer.
I restarted my PC but doesn't seem to have any effect.
I checked for Windows Updates but it does not find any new updates.
I used the Lenovo Service Bridge utility to scan my system and check for any updated drivers but it says I'm up-to-date. I went ahead and downloaded the Bluetooth driver package 75l804af086x.exe and did a manual install and then power-off / power-on but nothing has changed - I'm still on Qualcomm Atheros QCA9377 Bluetooth 4.1
