From Tech Tails reader Paul K.
“Hi Matt! I was reading Tech Tails and I have a solution to the problem you describe in your article ‘Let it Sleep.’ I used to be annoyed having to wait some seconds before my MacBook Pro would go to sleep until I found a preference pane called “Smart Sleep” which depending on the state of charge of a MacBook’s battery will trigger only sleep, deep sleep, or both (which is what the machine usually does: goes to sleep, but writes the content of ram onto HD, so that if the power runs out, in can be restored).
I have it set so that if my battery is more than 35% charged, closing the lid will instantly put the computer to sleep without taking the seconds to prepare deep sleep. In my case, the computer is sleeping by the time the lid touches the frame. I hope this helps you, and if you like it, maybe you can share it with other readers.
Cheers, Paul”
