I seem to recall hearing that you could throttle back the cpu on a powerbook to help conserve battery life. I tried a few searches but came up with nothing.

I have a 1 ghz Tibook, if you needed to know.

yes you can. It's an option in the Energy Saver control panel of System Preferences.

I see it.

Thanks for the quick response.

Does anyone know exactly how much power this saves? Isn't CPU a relatively low power draw compared to optical drives, hard drives and screens? can you increase battery life by, say, more than 10% by reducing the processor speed?

Short answer is "yes"...chip frequency is one of the big energy drains. The backlight is also a big one.

fun fact about screen backlighting...you can EASILY gain 45 minutes by turning your brightness to 1 or 2 notches
