SmartSleep: It’s a prefrance pane that will dynamically set the sleep state of your machine –
SmartSleep let’s you select each select sleep state. Additionaly the new SmartSleep state lets your notebook 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 the best of both worlds.
I just installed it, and it is very smart (ha!). SmartSleep recognized that I had changed my sleep mode to “0”. I set it to “SmartSleep” mode and actually the MBP sleeps even quicker than before. Consistently in about 4 to 5 seconds instead of 9 to 10.
(Much thanks to all of you who pointed this out to me.)
