Plugging in the machine was merely to simulate power restoration (a more accurate test would be to leave the DC connector attached to the laptop and cut off power to the AC plug, which sometimes creates different behaviour). I want a server to come back online unattended, so I can enjoy my vacations. :) I've only read that MacBooks overheat with the lids closed (I definitely feel the warm air being expelled near the hinge, and the area surrounding the track pad can get pretty hot), but if that's not the case, I might reconsider using them as servers.
