I have recently installed Ubuntu 14.04 LTS on a Compaq Presario C504EA (wiping off the old Windows Vista install), and I am trying to enable Bluetooth.
I have had a look on rfkill list all, the results are:
0: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
When you open System Settings | Bluetooth, it says Bluetooth is disabled, whether Bluetooth is switched to on or off.
Edit: the results of uname -a; dmesg | egrep -i 'blue|firm'
