Hello Anthony,
The command can't fix it, tested with the following steps:
1. sudo /usr/bin/setpci -s 00:14 d0.w=0x01db
2. Suspend
3. Wake it up and check the BT status
The Bluetooth indicator will grey out (stays at the "OFF" state), but
rfkill show it's not blocked.
rfkill before S3:
ubuntu@201406-15271:~$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
rfkill after S3:
ubuntu@201406-15271:~$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: no
