From following this list, it sounds like ACPI in FreeBSD is horribly broken on the vast majority of modern laptops. I am fortunate enough not to own modern laptops. :-) On my Toshiba Satellite 1605, ACPI suspend (to RAM and to disk) works flawlessly. It's worth noting that ACPI suspend-to-disk is several times faster than APM suspend-to-disk. This machine now runs Gentoo, however, because of the lurking M5237 USB bug (which I've finally gotten offers for help on, six months later, but can't have the downtime required to reinstall the OS twice to test). On my IBM Thinkpad 755CX, APM suspend (to RAM and to disk) also works flawlessly, and is much faster than the Satellite since it's maxed out with 40MB of RAM. :-) I recently picked up an HP Pavilion N5290 (like the other two, it died and was discarded by someone who couldn't solder); it's running Gentoo by default after my issues with USB on the Satellite, so I can't comment there. Hardware suspend doesn't work -at- -all- on it in Linux, but software suspend in their kernel does. You just have to manually patch your kernel to do it. Whee. -Cliff L. Biffle
