How do I restore bluetooth on resume.
I'm using Fedora 23 with Gnome 3.18 on a Lenovo G50-70.

Answer 1

The problem for me was with rfkill. Rfkill is responsible for radio devices and their state on startup and battery power etc.

$ rfkill list
0: ideapad_bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: no

The trick was to edit /etc/default/tlp. I needed to set:

RESTORE_DEVICE_STATE_ON_STARTUP=1
