There is a zigzag line across the icon & it says "Bluetooth: Not Available." Tried to restart my mac and checked the system preference but didn't work. Trying PRAM reset but shows up Disk Utility and there's maybe 4 options below (recover files from back up, reinstall OS, search online, disk repair). I'm hesitant so ended up restarting and problem still appears. What might be wrong? Please help.
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.5)
