I think Vista has a feature where it saves the RAM contents to disk and gets
into sleep (not hibernate) mode. If battery lasts enough to keep the RAM
alive, it will be fast to get out of sleep mode, unlike hibernation. If it
doesn't, you have the data saved to disk anyway, unlike sleep.

Or, maybe, the feature was that when it's running low on battery, it wakes
up, saves RAM to disk, and hibernates.

I don't remember the details.
