Thunderbolt won't wake from sleep on Mac Mini Server w/Lion 10.7.1

Hi.

I'm afraid I'm unable to offer a fix, because I need one too. 😟

I figured this thread was worth joining as my new display is showing an identical fault (intermittent power outs). Until now I've been doing force quits in order to get back where I was, but it's hardly satisfactory.

I've just set my energy settings to never sleep, in the hope that Apple get this fixed very soon. It's too soon for me to say whether this is an effective short-term solution, but further up this thread, that is suggested.

Good luck all.

yeah, choosing the never sleep option only shortens the life of your screen. makes no difference, so you're better keeping that on. The only thing that works is clicking the Auto Adjust Brightness option off. Stops all need to reboot the screen.

Thanks mate. I've reset as you recommended and will watch out for an update, to this thread or ideally, my kit!

Kind of relieved that I don't have to return the display, well, hopefully. 😐

Mac Air 1.6 GHz Intel Core i5 with Thunderbolt Display

Display often does not wake from sleep, until i reconnect the cable.

another issue is that even with the lid down on the lapton the display continues to share the screen, so the dock does not appear on the Thunderbolt

My 1yr old is climbing all over me now, so no time to write more!

For anyone interested, I clicked Auto Adjust Brightness option to 'off', as per Wazzafrog's suggestion, and haven't had the display cut out since (that's a week and some).

I think this is the fix until a formal bug fix is released.

Switching the auto brightness option off may work for those with a mac with an integrated screen or apple external display however for those with a mac mini and non apple displays this is not an option.

Mac Mini (non-server) with TB. Same issue (black screen, NB: but audio speakers working) once a day.

I'll try unchecking the "Auto Adjust Brightness" and see if it works.

A software update for Thunderbolt just got rolled out a few minutes ago!

Same here. The Thunderbolt update looks especially promising since it explicitely mentioned it fixes issues with users experiencing black screens 😁 Looks like we have our fix!

As one of the organ posters on this issue, I am with John from Maryland. My Mac mini server is now no longer timing out the display after 24 hours, using ARD and even my kids messing with my stuff!

Thanks for listening, Apple.

Even after the update I still have this problem, I'm using a VGA monitor, I tried everything, and it doesn't have the auto brightness option and definitely it's not a keyboard issue, because if I keep pressing the keys I can hear that default sound on the background. The only thing that works for me is, when it doesn't wakes, I need to unplug the thunderbolt vga adapter and plug it back, the monitor gets back to work in the same time. If anyone has any other workaround please tell me. I have the Mac Mini Mid 2011.
