Mostly for my own reference, since someone asked me recently and I didn't remember :-P

To mess with the hibernation / sleep settings on the macbook, you have to manually change your power management options using pmset.

To force hibernation instead of sleep, use the following command:
% sudo pmset -a hibernatemode 1

To switch back, just set hibernatemode to 0 instead, and you should be set.

Whoa, pmset lets you do all sorts of neat things. I just turned on autorestart for my desktop.

Hibernation is known as "safe sleep" in the mac world. Essentially, when you hibernate, you are writing out the contents of your memory to disk before going to sleep. Thus, its less likely that, say, if your battery decides its got to discharge right now, you will be forced into a hard reset.

You're restoring your memory state from disk when you wake up, so it takes significantly longer on wake from hibernate vs. wake from sleep. I tend to turn hibernate on when I know that I'm probably going to be shutting my computer down for a while or its low on power.

Have you found out how to shut off or otherwise control the infernal pulsing that all Mac laptops have while they're asleep? Nobody seems to know.

I'm pretty sure turning on hibernate also turns off the pulsing.
