A preference pane lets you either set the sleep state of your mac or dynamically sets the sleep state of your machine depending on the battery load. It’s a successor to Hibernate.prefPane.
SmartSleep lets your no>
tebook just sleep while the battery has a high level. If the battery level drops below a certain point ( default is less then 20% or 20 minutes ) it will switch to sleep and hibernate. So you have a fast sleeper while the battery is at high load and safe sleep when the battery is at risk to get depleted.
What’s New in this Version - Fixed minor issues on 10.4 - Nicer slider behaviour - Added ability to remove the sleepimage.
