    Hey guys, when my MacBook Pro (2.16Ghz merom) goes to 0% battery it doesn't automatically go to sleep anymore - it just turns off.

    Can anyone give me help?

    recalibrate battery?

    1. Charge battery fully.
    2. check if you have enough disk space for sleepimage
    (> 4 GB should is OK)
    3. reset PRAM:
    4. recalibrate battery (if necessary):

    Check if there are no devices (especially bluetooth) that can wake your computer.
    - turn off bluetooth
    - disconnect external harddrives
    - turn off airport

    After resetting PRAM and recalibrating you battery, let me know if it has helped.

    Also, checking disk permissions and running cron tasks seems like a good idea. Onyx can do both maintenance tasks.

    Hope this helps.

    All the best,
