What you're looking for is what's typically deep sleep in the Mac world and hybrid sleep in Windows and is the default way Macs behave. Trouble is that unless you really work at it (and some luck seems to be involved also since it works for some and doesn't for others) and you make hibernate work enabling deep sleep wouldn't accomplish anything. Otherwise the hibernate file created is junk and won't work. Problem is even if you got it working, then could automagically delete the sleepimage upon waking, you'd still be using up that 1G of SSD
space each time you slept.
Which means you wouldn't be accomplishing what you say is important in your first post in this thread and not used up that 1G of SSD
So just set the hibernate mode as above, delete the imaage file and use just sleep and never sleep so long the battery dies
Or live with loosing the 1G of SSD
space and make real hibernate work. Once you've got that you can then choose to hybrid sleep or just sleep.
