Deep Sleep... The default behavior of Mac OS X is to put sleeping computers in 'hardware suspend' mode, during which the RAM is still powered on. This widget allows the computer to enter 'software suspend' mode. Software suspend is a feature similar to what windows call 'hibernation': the computer consumes no power while sleeping, however the wake up process takes more time to complete.

Hibernation is made possible by the Mac OS X Tiger 10.4.3 update. This operating system version is required.

Only the computers with 'safe sleep' feature are officially supported. For now, the only computers with this feature are the Powerbook
