When you are not able to turn on the Bluetooth in your Asus laptop then do this:
Go to your Windows desktop > select Control Panel > select Device Manager or else type devmgmt.msc in the Run box (Windows +R keys) to go to Device Manager.
Find many devices in the left panel of your computer. Then click on the drop down menu of Network.
If there is no Bluetooth there, then there is no Bluetooth in your laptop.
In the case of it being there and not working, then do a right-click on it and choose Properties to find out why the Bluetooth is not working in description.
Then right click on the Bluetooth and uninstall it.
Now, turn off the computer and then turn it on.
The laptop would detect the Bluetooth Bluetooth device and try installing on its own. If in case you have a new driver, choose that.
