For a while now I've been having issues with the Bluetooth connectivity completely disappearing. It's more than simply dropping the connection as when you look in Device Manager it tells you that the computer has NO Bluetooth facility at all - not even any hardware to run it!
This started happening after I installed various updates from HP Support Assistant. It seems to be a BIOS update which did it. When I went back and reinstalled the previous BIOS file Bluetooth is back but it often disappears again but comes back after I reinstall the BIOS file again. The most recent BIOS update sp112679 simply will not work at all as far as BT is concerned and even causes WiFi connectivity to stop working as well.
The BIOS fie which works (but keep losing BT eventually) is sp111748.
