Equipment: Early 2013 MacBook Pro running Mountain Lion Connected to an Apple external display.

We boot natively into Windows 7 so that we can use the full capacity of the graphics card and we use the external monitor with the lid of the MBP closed. However, when we open the MBP lid its' screen won't wake up, no matter which keys we press. We must perform a hard reboot using the power key to restore the MBP screen.

I don't know if this is related to the Thunderbolt issue but we do have ethernet connection via a Thunderbolt adapter (for connection to the Exchange server drives and network) and an external hard drive (back-up).

Is there a setting in Windows or a key stroke combination that can solve this problem.

This is a known problem with Thunderbolt. Windows doesn't officially support Thunderbird, and devices need to be turn on before Windows boots.

However, to avoid this problem, Apple has disabled sleep when Windows is booted with Thunderbird. So I'm not sure why your Mac can sleep. See this article:

Thunderbolt limitations of Mac running Windows: a feature, not a bug. Sort of.

In any case, Thunderbolt is the likely culprit.

Thanks for the feedback. Understanding that this is related to Thunderbolt helps. I don't believe we have the latest version of BootCamp installed so this may be the reason for the "wake" hang-up.
