ok, lets see... it is supposed that once the display is on sleep also the auto-sleep function gets activated after some time if you do not enable the "prevent computer from sleeping automatically when the display is off" in System Preferences! However, this is obviously not the case. The Display goes off but the hack never enters the sleep modus. When you want to wake up the display after 5 minutes with the keyboard it does not respond! However, this strange behavior only can be witnessed when "prevent computer from sleeping automatically when the display is off" is disabled in System Preferences. Under normal working conditions ("prevent computer from sleeping automatically when the display is off" enabled), the display can turn off and it can always be activated with the keyboard. The same states for forced sleep and subsequent wake. The problem you describe above is exclusively related to the auto-sleep function which seems not to work at all. I still don't catch what you mean with computer sleep. I guess you refer to auto-sleep! The forced sleep and subsequent wake always works !!!!
