It's wrong on two counts, at least on my 7.0-R and your 7.2-R; you're right that acpiconf doesn't try S5, and AFAIK S4OS does not yet exist on FreeBSD, so the handbook is, er, a bit optimistic in a couple of places! (I haven't checked what's new in 8.0, but think I'd have heard if S4OS was any further along than an incomplete Google SoC project a while ago) To be fair, acpi(4) under S4 does say that S4OS isn't yet supported. Here S5 (from the power button) works fine on my Thinkpad T23; properly running shutdown scripts and synching disks before powering off cleanly. And S3 (suspend to RAM) and subsequent resume works fine either by using acpiconf -s3 or the sleep button, which is Fn-F4 here. You didn't mention whether your system works with S3 suspend/resume? So just for kicks I tried acpiconf -s4 which hard powered down, without properly shutting down or synching disks (ie dirty after reboot) which I guess is a "don't do that then!" though in theory it should check that S4bios is 1 (or S4OS has arrived!) before diving off into space. > I discovered that the motherboard is actually made by Foxconn a > 945GZ7MC.

There are some things you could try before (or while preparing to) submit a PR, in the light of scanning your posted AML. Have you tried? (from handbook): 11.16.3.5 System Powers Up After Suspend or Shutdown "First, try setting hw.acpi.disable_on_poweroff="0" in loader.conf(5). This keeps ACPI from disabling various events during the shutdown process. Some systems need this value set to 1 (the default) for the same reason. This usually fixes the problem of a system powering up spontaneously after a suspend or poweroff." And/or from acpi(4) have you tried? maybe playing with: hw.acpi.disable_on_reboot Disable ACPI during the reboot process. Most systems reboot fine with ACPI still enabled, but some require exiting to legacy mode first. Default is 0, leave ACPI enabled. hw.acpi.handle_reboot Use the ACPI Reset Register capability to reboot the system. Default is 0, use legacy reboot support. Some newer systems require use of this register, while some only work with legacy rebooting support. Now I know very little about AML, and the folks that do must be on holidays :) but starting at the end, methods PTS and WAK are clearly about suspend and wakeup, and method _PTS refers to OSFL () which returns OSVR according to OS version: if I read it right, 4 for win2k and NT, 0 for most windows versions, 2 for winME (hee) and - perhaps usefully - 3 for Linux, and 1 otherwise, with reference to: 11.16.5.1 _OS dependencies "Some AML assumes the world consists of various Windows versions. You can tell FreeBSD to claim it is any OS to see if this fixes problems you may have. An easy way to override this is to set hw.acpi.osname="Windows 2001" in /boot/loader.conf or other similar strings you find in the ASL." OSFL is called in various places as well as in _PTS (put to sleep?) so a choice may well influence other aspects of ACPI as well as sleep states. (If anyone who actually knows what they're talking about is out there, please chime in; you can see I'm paddling way out of my depth ..) cheers, Ian
