I removed hibernation, and deleted the 4GB file from my MBA, is it possible to get it back? I want to see if it saves any battery by having it go into hibernation instead of just sleep.
Got a tip for us?

It won't change your battery life. Once the MBA writes the sleepimage, it goes into the exact same sleep mode it goes into right now. The sleepimage is really only for when it runs out of power, or goes into deep sleep mode just before running out of power.
You could set your Macbook Air to hibernate only. In this mode it writes the contents of the ram to the disk then turns off the system. Then when you press the power button to turn it back on, it'll read in the disc contents and put you back to where you where. It uses no battery life in hibernation only mode.
How long does it take to come out? Where can I enable this as well? I will run :
sudo pmset hibernatemode 1
to turn it back on, but how do I tell the MBA to hibernate with 15 minutes of inactivity and not just sleep?
