Hello damir,
Please kindly check if your BIOS has been updated, and install bluetooth driver again.

Dear Blake, I thoroughly checked and updated everything I could possibly find. Including of course BIOS and Bluetooth drivers.
It didn't help. Nothing did. Not even reinstalling the Windows! I've spent tens of hours.
But you know what eventually did?
I inserted USB BT dongle which was immediately recognized by Windows via generic Bluetooth driver. Bluetooth icon appeared in device manager.
I waited for few minutes for generic drivers to finish installing.
Turned off my laptop.
Removed the USB dongle.
Turned on my laptop.
Done.
