    I love that the new MBs and MBPs allow for hibernation, but there is one feature that I can't seem to find any reference to. Is it possible to set up (or hack) Safe Sleep to allow the computer to hibernate after it has been sleeping for a certain amount of time?

    I like that the computer will deep sleep if the battery is nearly dead, but I want it to deep sleep after 30 minutes or something, not after 2 days when the battery level is so low the computer can't sustain power to the RAM.

    Are there any applications available to modify this? I'm going to be getting a new MBP in the next week or so :) and I want to make it as perfect as possible.

    I'm pretty sure all intel-based macs go into a hibernation once its white LED starts the glowing "sleeping" gesture.

    You can test this by closing the lid, wait about 10 seconds, take out the battery, put it back in, open it back up and push power.

    PowerPC macs (old ones) cannot do this.

    Oh really? I didn't know that, I thought that when you closed the lid it went into a regular sleep, and then had a capacitor that lasted maybe a minute max without the battery in order to facilitate someone wishing to pop in a new battery while running their computer. One learns something new every day, i suppose.

    There is no way to 'turn on' Safe Sleep... it is on by default.

    When you sleep your computer, it dumps out the RAM state to disk, so that if you /do/ lose power for whatever reason while it is sleeping, you boot straight back up to where you were.

    Huh, I did not know that. I thought it just stopped the hard drive from spinning and used up only enough battery life to keep the RAM active. Well, this sounds cooler anyway.

    That is what sleep does. :)

    Safe sleep makes sure your data is safe while the computer is sleeping. :)
