Is there a way to set a MacBook Pro (10.8.2) to go into normal sleep when I close the case but then switch to hibernation after, say, 15 minutes? It's clearly capable of going from sleep to hibernate when the battery runs low, but I haven't been able to find out if that behavior can be triggered by anything else.
Background: I need to use Filevault encryption, and my understanding is that it doesn't provide much protection if the computer is stolen while in normal sleep mode. To remedy this I've set it to hibernate instead of sleeping and enabled the
DestroyFVKeyOnStandby option. But this is very inconvenient when I just want to put it on standby for a few minutes (e.g., put it in my bag, walk to a meeting upstairs, open it back up).
