Under "Energy Saver" you can choose "Better Energy Savings", "Normal", and "Better Performance". As you pick each of these options, the only visible change is the computer sleep timer and the display sleep timer. Does anything else change? The main thing I'm wondering about is the difference between Normal and Better Performance. According to this screen, the main difference is that in Normal mode, the computer will go to sleep in 15 minutes. In Better Performance it'll never go to sleep. Is the better performance truly just related to the amount of time it takes to wake up the computer, or is there something more going on, such as CPU speed? If it's more, can anyone quantify exactly what changes? I've searched around for this, but I haven't found the specific answer; I've mostly found comparisons between multiple computers (heh). Posting in the MBP forum because I have a MBP. I assume that'd change the exact speed values, if they are changed.
