I will start by saying that I have reset pram, nvram, and PMU. The laptop seems to not sleep at random times. I can almost always reproduce this if i simply leave it on, and unplugged from the charger and open. The screen goes dark as normal (I have it set that way) after a few minutes but the laptop never goes to sleep and eventually just runs the battery down. This seems to also happen sometimes when the laptop is shut, and I think its sleeping, it seems to run the battery down faster than it ever used to. I have an apple battery that was replaced by apple for me through the battery replacement program about 4 months ago so by all standards the battery is "new" I am running 10.4.9 on the machine listed below. What else can I try?
