Is anyone else experiencing this problem?? I don't remember exactly when this started, perhaps after 10.4.3, but it seems that my PowerBook doesn't go to sleep when the power adapter is connected anymore. Now I have checked in the energy saver preferences for all of this. But what happens is I am at work and I check something on my computer and then I leave, only to come back and find my computer still awake. Because it is awake the whole time, and having to power the screen and do processes and stuff, it is also fairly warm. Is anyone else having these problems??
