10.4: Enable safe sleep on some older Macs
Authored by: xavierbdm on Nov 19, '05 07:36:26AM

Safe sleep does not what you say it does.
Setting up safe sleep on a machine, means that EACH time your laptop goes to sleep it will save the RAM to disk, EVERY time.
It is meant as a safeguard.
That is why you can pull out the battery and the power cord of a laptop that has the feature activated (but was put in sleep the "normal" way), and get it to wake up afterwards.
The laptop never wakes up to save RAM to disk when battery is low.
(that would be relying on battery having enough back-up juice left to actually do that. It is the Windows implementation. Clumsy, unefficient and dangerous too -imagine if the laptop is being bounced in a bag while waking up to enter hibernation-)
