Hi Rob, There are at least a couple features at work since the PowerBook days. Firstly, 'sleep' basically only needs power for its power management unit, Bluetooth (optional), USB bus and RAM. This is done by the mains adaptor, the main battery, or a small internal battery that lasts about 3 minutes with the basic amount of RAM. So, you can be without AC and Battery for about 3 minutes while you swap batteries, then wake up normally. Secondly, there is 'safe sleep' ('hibernation'). Mac OS X reserves a space on disk for saving your RAM. If the system foresees a depleted battery, it writes RAM to disk you do not need any power at all. Waking from safe sleep takes longer than regular sleep, since it has to read the RAM off disk first.
