Keyboard is on but will not type
If your Keyboard is on but will not type it may be on the wrong input.
You can try pressing the White keys on the top left of the keyboard and attempt to type after selecting each one.
If this is not the issue your Bluetooth may be turned on for the device.
You can do this by searching for "Bluetooth" in the search bar at the bottom right of your taskbar.
Next make sure that the Bluetooth toggle is on and marked with Blue.
