Q: MacBook Pro mid-2012 OS X thunderbolt screen won't wake up
For no apparent reason thunderbolt screen started to hang my MacBook Pro mid-2012 when I tried to wake up the screen. When I disconnect screen MacBook works fine. I unplugged the screen and left it powered off for few hours and reconnected it to a direct power socket and it woke up. Moved back to the original power socket which I've been using for years without issue and it's not working again. All connectors look fine, it doesn't ever move from my desk. I applied latest updates, tried to reset nvram which brings me to OS X utility for some reason (Cmd option P and R) after startup sound. Any suggestions would be greatly appreciated.
MacBook Pro, OS X Mountain Lion (10.8.5)
