Hello all, I just purchased a new MacPro 3GHz XT1900 machine. To keep things tidy in my workspace at home, I have the machine in a storage location within my desk. I noticed the computer ran pretty hot, and that the bin was getting warm. So rather than run it at all times, I thought I would put it to sleep more often than my previous computer. However, when I put the MacPro to sleep, it awakens 5 seconds later. I have the computer connected to an airport via ethernet. I turned off the settings for awakening the computer based upon administrator access. I checked the box for allowing the power button to sleep the computer. I have tried placing the computer to sleep using the power button and menu command. None of the methods results in the computer staying asleep. Appreciate any suggestions or chime-ins if you are experiencing something similar. For now, I am simply shutting the system down when I leave the desk.
