Thunderbolt Display will not wake up after sleep!!!!!!

Hi there, after much exhaustion, and trial, the only thing that fixed was replacing the MacBook Air. It worked flawlessly for a year... until yesterday. I started having problems again. It seems to have something to do with the power to the Mac. Sometimes it now doesn't charge when I plug it in securely.

I wish I had better news!

Hi guys,

You should gather on this thread, as many users have the same kind of issue, not only with wake up:

Cheers.

FYI, you don't need Alfred.

Command-Option-Eject will do the same: http://support.apple.com/kb/PH11242

This update improves reliability when connecting devices to the Apple Thunderbolt Display, and addresses a rare issue that may cause the display to go black.

Thunderbolt Display Firmware Update v1.2

There's another thread about it here Thunderbolt Display "dead" after firmware upgrade to Version 1.2

This firmware update may help.... Thunderbolt Display Firmware Update v1.2

I was having a similar problem with MBP, make sure under bloothtooth advanced setting you have the "Allow Bluetooth devices to wake this computer" box checked. That resolved my issue.

Same problem, and the bluetooth setting suggestion has nothing to do with it for me.

I got the same problem with the same new mac mini server, and am using a USB keyboard,,,,

Just did it to me again. No luck. Gonna have to buy a light switch for the power outlet to keep resetting it...

This no longer works for me 😟

Just to increase the count....I am having the same problem. No wakeup, no sound, nothing...

One more, same problem here... any new suggestions?

Correction, It's doing it now, without it going to sleep. I've turned off auto brightness. Something I don't want to do.

I just updated my MAC OS to the latest 10.8.2. I dropped the resolution and turned off sleep mode. We will see if it keeps doing it.
