Wake Up Your Mac Faster

What would really be nice is being allowed to say: Suspend to RAM if battery left > n% else, suspend to RAM and disk. That way, you get the best of both worlds.

    Yes, indeed, SmartSleep works great. It gives you a pref pane interface for toggling between sleep, hibernate and 'smart sleep' -- which hibernates if the battery is low, but sleeps otherwise. I've been using it for the past ~6 months. Without it, my MacBook would take nearly two minutes of disk activity before sleeping; now, it's sleeping happily within 5 seconds.

  I believe that's already the default behavior of OS X. It will put the computer to sleep (ACPI S3), and start dumping contents to hard disk. If the battery dies or is removed between waking, it will read it in from disk. I'm not 100% positive on this, but I do recall reading a similar description.

This is actually putting your Mac to sleep, not wakng it up, faster. It's going to wake up fast as long as you are reading from RAM. This "hack" makes it sleep faster by skipping the write to disk.

There is a reason it's called "Safe Sleep". If you have forgotten to save files or a number of other thing and get powerloss RAM only suspends are gone. That could really suck. Personally I can live with the extra small delay. I've toyed with these settings before. Suspend only to disk is too unstable because it's trying to write to disk while you are moving the laptop around closing it/picking it up/etc RAM only sucks when you loose power. I'm happy to stick with the default. I would like it if someone wrote something that suspended to RAM and then copied to disk when the tilt monitored guaranteed it was safe and then turned off the computer. When traveling the power suck from powered suspend is really annoying.
