The problem I have been faced with can be seen here :

The ASL dump of the DSDT is obtained with acpidump(8).

Once you have the patched DSDT, you may want to load it automatically
at boot time.  Put it in /boot/DSDT.aml and then add this to
loader.conf(5) :
% acpi_dsdt_load="YES"
% acpi_dsdt_name="/boot/DSDT.aml"

I hope this will help.

I don't know if this problem is FreeBSD-specific.  I have an Acer laptop
too but not the same model as yours, so you may simply not encounter
this very problem actually.
