Ubuntu Desktop 20.04 does not see the built-in Bluetooth adapter (Asus X54C laptop) - what to do?

Question

Bluetooth

I recently switched to Ubuntu, under Windows the adapter worked fine.

And under Ubuntu, it tells me that "the adapter is turned off" - but how to turn it on? )) it seems to be non-switchable))

In general, I have no idea which side to take.

Google mumbles something indistinct)))

Help, huh? )

upd.: googled this:
