I'm somewhat of a minimalist and don't use X11. I've disabled the bluetooth adapter, but frequently use my wireless adapter (intel pro/2200bg). Does anyone have any suggestions that could potentially extend my battery life?

Have you tried reducing HZ to 100 (put kern.hz="100" in /boot/loader.conf and reboot)? Are you running powerd? Look into "sysctl hw.acpi" and "sysctl debug.cpufreq"....

Thanks for the ideas Chuck. I lowered kern.hz to 100 as you suggested (does this affect the kernel's ability to track time in milliseconds? ie. if I want to run a benchmark using the 'time' utility?). And the output of the two sysctl queries is posted here:

I'm not very familiar with acpi, so if you see anything that could be optimized, I'd appreciate the feedback.
