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?

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.
