You may need to edit some of your ACPI settings in sysctl: http://www.freebsd.org/doc/en_US.ISO...cpi-debug.html + http://www.freebsd.org/doc/en_US.ISO...ng-sysctl.html

You could also try depressing the power button after halting the system in order to manually turn it off.

According to here the ACPI is fully supported on your laptop, so it should work. I imagine you are seeing a System halted message and when the laptop stops working. Have a look at /boot/loader.conf, there is an acpi line that disables throttling, maybe that could help. Besides, it is very strange it does not work out of the box.

Yes, it is strange. Actually, it is _somewhat_ similar to a minor bug I have with my IBM Netvisa desktop machine. If I run $ shutdown -h now or whatnot, the system runs through the shutdown process, but fails to actually power down the system. Pressing the power button, on the other hand, initiates the same sequence but also powers the system down.

I guess that means it's worth investigating different methods for shutting the system down -- if one doesn't work, another one might.

I Tried messing around with /boot/loader.conf, still it doesn't work, and I found this thread about add a "hw.acpi.disable_on_poweroff=0" in sysctl, I've tried added to "/ect/sysctl.conf" and still no luck

in "#sysctl hw.acpi" still not showing up the "hw.acpi.disable_on_power=0", does anyone know how to add those line into sysctl? and does anyone have anymore solution for my problem?

I want to declare, up front, that I've never edited sysctl myself before, and am far from being any kind of expert. I'd really recommend that you run:

Code:

$ man sysctl

... and consult the documentation closely (in addition to the section of the FreeBSD handbook I linked to earlier). The format for writing to a sysctl variable is as follows:

Return the Value of the Variable

Code:

$ sysctl -a | grep ttl
net.inet.ip.ttl: 64

Modify the Value

Code:

$ sysctl -w net.inet.ip.ttl=100
net.inet.ip.ttl: 64 -> 100

Return the New Value

Code:

$ sysctl net.inet.ip.ttl
net.inet.ip.ttl: 100
