Hello everyone. I just upgraded from an old iBook G4 to a shiny new Macbook. On my old iBook I could adjust the cpu speed to a lower value to get a longer battery life (only about 20 minutes though) and/or a lower fan speed. On my new Macbook these preferences vanished from the "energy saver" options dialogue in the System Preferences. How can I enable them? Are the CHUD tools maybe of interest? Thanks!
