My laptop's bluetooth is gone. I have not been using it for long time and I set it to turn off from settings. Months ago, Windows Defender will always notify about Apps and software devices issue for bluetooth that it has problem even though its always turn off and I'm not using it. It will have issue in Device performace & health section in Windows Defender and will prompt to troubleshoot bluetooth but troubleshooting it doesn't fix it. The issue only fixed after I restart the PC. This issue happens many times. This day we bought a bluetooth speaker and I decided to try to use it with my laptop then I noticed I don't have bluetooth turn on/off from Windows Settings.
I can do basic troubleshooting myself so I decided, maybe I just need to disable/enable update/reinstall the bluetooth driver from device manager but the bluetooth is
not showing anymore form the device manager, even show hidden device is active.
The first thing I did was to do the
bluetooth troubleshooter from
Update & Security >
Troubleshoot. It shows
Device does not have bluetooth.
So I decided download the Intel bluetooth driver from the official download page and trying to install it only prompt me that
a newer version of driver already installed, probably from Windows Update. I want to try to reinstall the driver but I can't find it in device manager so I go to Control panel > Programs > Programs and features.
Uninstalled the
Intel Bluetooth Driver 21.40.0.1. I do save screenshot before uninstalling. Shows installed just today. I just update my windows from 1803 to 1903 on Nov 11. I also do windows update earlier this morning.
I also go to
services.msc to restart and set
Bluetooth Support Service startup type to
Automatic then I restart my PC. I check first again to device manager and look if bluetooth possible show up, found nothing. Installed the lower version driver from the official download page and do a restart again. Still nothing.
I try scan for hardware changes in device manager. Still no bluetooth. I guess I haven't been able to use the bluetooth and I'm really planning to buy a wireless earphones to use. Hopes my laptop's bluetooth is not broken I don't like to use bluetooth dongle, I'm already using USB Bluetooth Logitech mouse. I would have less unavailable usb ports to use.
