Why can I no longer switch on Bluetooth on the laptop?

Yes, hello my problem is that I can no longer find the Bluetooth button in the settings and can therefore no longer connect my devices. Maybe someone knows a solution…

I would be glad

Perhaps the hardware is moderately switched off, by sliding switch on the front or side, or by FN + F (xx) - xx stands for F1-F12 depending on the laptop (the Bluetooth symbol should be on the F key.
