Hi:

If there is no Bluetooth device manager category in your notebook, most likely the BT was turned off during the upgrade to W10.

W10 automatically installs the Bluetooth driver.

To turn the Bluetooth on, you can do the following...

Make a bootable Ubuntu installer (Ubuntu Desktop).

https://ubuntu.com/download

Boot from the Ubuntu installer and select the option to Try Ubuntu without installing.

Then there is a setting to turn on the Bluetooth.  Turn the Bluetooth on, and now you can exit out of Ubuntu.

When you restart the PC, W10 should install the Bluetooth driver and you should be good to go.

Ubuntu did not work

Then most likely two things are possible...

1.  Your notebook did not come with built in Bluetooth networking.  A few 8440p's didn't.

2.  The HP Bluetooth module died on you.

If Ubuntu didn't find a Bluetooth device to turn on, then I don't have any other suggestions for you to try, because I know it works if the BT radio is functional and was turned off in the HP wireless assistant or HP connection manager software.

Go into your notebook's BIOS and see that the Bluetooth device is turned on in the BIOS (enabled).

The only other thing you can do would be to reinstall W7, use the HP wireless assistant or connection manager to turn on the Bluetooth, then once the BT is turned on, uninstall the HP wireless assistant or connection manager software, restart the PC, verify the Bluetooth radio is still turned on, and then upgrade back to W10.
