Can you fix this please? After using the “Safe Sleep Now” option, your program doesn’t set the old hibernate mode correctly, it stays at 1, although it should be 3 in my case.

On the PowerBook and MacBook Pro this functionality is enabled by default for certain situations (battery swapping is one). However, my SafeSleep script lets you put your system into suspend-to-disk on demand, just putting the system to "sleep" only does a suspend-to-RAM by default. Use the "Always use Safe Sleep" option if you want the system to go directly into safe sleep when you put the system to sleep. The links provided go into depth about the differences between them, and the comments on those articles cover the questions and confusion people have had with this feature. Tomis Responds

I've been using software suspend (just another name for it) for about 18 months on both an AlBook and a MBP and I just pop into Terminal and input sudo pmset -a hibernatemode 1 And it works just fine.

sudo pmset -a hibernatemode 1

And it works just fine. Am I missing something?

Just drop it on ScriptEditor.app and you'll get the complete source code along with a nice little header and comments. I figured other coders would like to know how it works as well. But really the hard work was done by the guys at the URLs I cited. I just wrote a nice AppleScript to wrap up the terminal commands. If you use any of this in your project then, at the very least, cite those URLs so others can learn how the underlying system works. Thanks! Tomis Responds

This halts processing and other energy draining procedures but it still takes up battery life. With SafeSleep the system will suspend-to-disk. Eating up as much power as if it were completely shut down. The upshot is in battery savings, the downside is it takes longer to suspend/resume from disk than to ram. Considering SafeSleep works by using built-in system commands, simply enables a feature that is already present but hardly used, and doesn't involve "hacking" the system in any way, I seriously doubt it would void the AppleCare warranty. And I can't imagine any issues it could cause that the normal trouble-shooting procedures wouldn't fix. But you'd definitely want to read through the AppleCare agreement thoroughly to be sure.

Also if Apple doesn't support it as such, does that mean they could refuse Applecare service if they find it on your system? Thanks. How does SafeSleep relate (or not relate?) to closing the lid?
