I'm running -STABLE on a Latitute D800, so I can sympathise. It took a fair bit of reading and poking around, but I found this to be a good start: * Add these lines to your /etc/rc.conf file: (options are detailed in powerd(8)) powerd_enable=3D"YES" powerd_flags=3D"-a adaptive -b adaptive -p 2000" That will probably get you a long way there just by allowing the CPU to slow down during inactive periods. Don't ask me about getting the darn thing to suspend, though. Every time I've tried it has failed to come out correctly. And keep in mind that there is no suspend-to-disk support (called "Hibernation" in Windows) for FreeBSD.
