SafeSleep ... Mac OS X 10.4 improved a little-known feature of Mac OS X; in a low-power situation the contents of memory will be saved to the hard drive and the computer will shut down. On other Operating Systems this is a standard feature known as Hibernation or Suspend-to-disk.

SafeSleep lets you quickly and easily put your laptop into this sleep mode on demand. I have been using it for several months without any problems. But note that this usage of the functionality is not officially supported by Apple.
Requirements
Intel/PPC, PowerBook, iBook, MacBook, and Mac OS X 10.4 or later

It would be nice to know exactly what commands this utility runs. This would be a great solution for our users, but not something we can consider before knowing exactly how it works.

It does work. But, once it is used, regular Sleep command from Apple Menu no longer functions for regular Sleep, it only works for hibernation. How do I disable this to get back to regular Sleep? Apparently this is possible, but even though I select regular Sleep from within the application, it still hibernates when I select Sleep from the Apple Menu.

Sounds like you've selected "Always Use Safe Sleep"

To turn this off, select "Only Safe Sleep in Emergencies" (which is the default behavior for machines that ship with safe sleep enabled) or "Disable Safe Sleep"

Works perfect on my Core 2 Duo MBP w/ 3GB. Thanks for contributing this.

Works beautifully on my 17" PB...nice job!

I had given up the idea of hibernating my PB when I read a while ago it wasn't compatible...I guess they were wrong...Thanks!

This doesn't appear to work on my 2.66 GHz Mac Pro. Selecting "Safe Sleep Now" causes the machine to go into normal sleep - no difference.

It does that for my mac, also. I thought it might have been my mac, since this computer is four years old already.

Worked flawlessly on my 2.0 GHz Core Duo iMac. I have 2 gigs of ram in my machine, so a little sluggish going into and coming out of hibernation, but functioned perfectly otherwise. Compared to just booting up normally, I think it was about twice as slow, but if you tack on the time it would take to start-up all the applications one had running, it's probably a bit faster in the long run.

Quite the interesting (hidden) MacOSX feature. I know it's kind-of silly to use it on a desktop machine, but I still think it's pretty cool. Gives a glimpse at what the performance and methodology behind any future flash-equiped Apple notebooks might look like.

why is it silly to use on a desktop? it's a great place to use it. just as you said, you can deep sleep, save energy, reduce noise, without closing your apps and files.

I tryed on PowerBook G4 12in (867MHz).
"Safe Sleep Now" is good performance.
But choiced "Always use Safe Sleep" is not performance.
Because normal start up , when not wakeup at low battery auto sleep.
And Safe Sleep(ing) time is not GUI presence.
I feel good features, but more up stability,
