It might be helpful to mention your windowing
system, but I doubt that it will make a lot of difference.

Most likely, FreeBSD doesn't "grok" your system's
ACPI.  What does "uname -a" say? (Let's establish
your OS version first).

Do you have any references to "ACPI" in your system's
boot message?  (you can look in /var/run/dmesg.boot).

What does kldstat(8) show?  Is "acpi.ko" loaded?

It is quite possible, if you are running a relatively
recent release on an older machine, that ACPI support
is intentionally disabled for your motherboard because
FreeBSD considers the system's BIOS/ACPI to be
"broken".  If this is the case, I'm not sure if the
situation can be corrected, or not.  The good news:
sometimes it is possible to tell the system what kind
of ACPI support you need, and have it loaded at
boot-time; the bad news: some motherboards/BIOS
will never be supported, there simply won't be
enough programmer time to devote to all the
whims of every chipset designer who's been allowed
to release a product.
