Specifically, it seems like my processor changes a whole lot, and I'd like to try to encourage it to change less frequently, and stay in the lower power states longer. If anyone knows, could you give me a few pointers? Or perhaps point me at some documentation? I haven't been able to find much about this specific type of need. Thanks, Lincoln
