I have a long standing issue with a 30" cinema display plugged into a closed MBP.  I have display sleep set to 15 minutes, and the display does indeed go black after 15 minutes.  However, in less than a second after blacking out, the display comes back on.  The display is connected to a USB Apple extended keyboard, 2 Griffin PowerMates, and a Wacom Intuous tablet.  There's also an Apple BT trackpad.


This used to happen with a 2008 MBP and now it's happening with a rMBP that was built from scratch (i.e., nothing was copied over from the old MBP).


Any ideas on what could be causing the instant re-awakening?
