Apple has had this feature for years on some models. At least as far
back as the first titanium PowerBooks. I'm not sure exactly how it
works; presumably there's a small battery or capacitor or something
built-in that can power the machine for a couple minutes.

I don't think the current 12" model does this, but it's an advertised
feature for the 15" and 17" models.
