Bluetooth unavailable after opened up the back

I bought an Optibay drive to install a SSD.

After putting everything back (And I'm sure that everything's backed)

No problems at all except my Bluetooth became unavailable, may I know how can I fix it ? I tried every solution posted on web including repairing disk permission, double check all the preference panes thing, logged in as root user to repair and so on.

I suspect that it's the hardware problem, but I don't know how to fix it, kindly give me few advice please.. I really appreciate it :)
