    When I close the lid, it takes about 30 seconds for the MBP to sleep.

    I have the early 2011 MBP with 4GB of RAM. The only app I have open is Chrome.

    My late 2008 MBP prior to this used to sleep within 5 seconds.

    Any ideas?

    Whenever the newer macs sleep, they write the contents of the ram to the hard drive as a safety precaution.

    If you want to disable the feature and have it sleep automatically, type the following in terminal:
    sudo pmset -a hibernatemode 0

    edit: Also, there will be a sleepimage file somewhere on your computer a little bit larger than the size of your ram. If you disable the safe sleep feature, you might as well delete that image to save a little bit of space. The article above goes into detail on to get rid of it.

    I recently did this on my ancient Core Duo, since it was having intermittent trouble waking up from the "3" safe sleep after reopening the lid. Now it works perfectly.

    Thanks! So if the battery runs out, it won't "resume" like it did before?

    Sometimes my MacBook Pro doesn't sleep when I close the lid. What I do it open the lid and shut it again, then it instantly goes to sleep. Try it.

    At least yours goes to sleep...mine sometimes just idles with the screen off...leading me to believe that it's on sleep mode...I've left it like this in my bag for 3-4 hours...coming back to the screaming fans and the laptop being super hot. Be glad yours isn't like mine lol.
