Q: thunderbolt display won't wake up!

I bought the first version of the MBP Retina and I'm loving it! So what better companion to use than the 27" Thunderbolt Display...

 

So I've been using it since the first day I got my MBP Retina. Everyday when I leave work, I log-out from my computer, and when I get in in the morning, I just move my mouse and both my displays wake up. This has never been a problem until this morning.

 

I have tried unplugging the power, doing a power cycle, disconnecting all USB devices from the Thunderbolt, etc. Nothing works.

 

Does anyone have an idea?

MacBook Pro with Retina display, OS X Mountain Lion (10.8)

    I have a related problem:

    My thunderbolt display is connected to a Retina iMac.

    When the iMac sleeps and wakes the Thunderbolt comes back on if it had been on. If the iMac is restarted the Thunderbolt display won't come on. The solution of me has been to disconnect the Thunderbolt display, restart the iMac and then connect the thunderbolt display. It will immediately come back on. It seems to me this started with El Cap.

    At any rate I wish restarting the iMac didn't require disconnecting and reconnecting the thunderbolt. The iMac must be off when the Thunderbolt is disconnected. Sleep wake fine, restart disconnect the Thunderbolt first. Reconnect Thunderbolt after restart then all OK.
