For my Dell's, I usually added a line into rc.suspend and rc.resume, to
toggle the acpi video sysctl. Something like:
sysctl hw.acpi.video.lcd0.active=0
in /etc/rc.suspend, and:
sysctl hw.acpi.video.lcd0.active=1
in /etc/rc.resume.
Now, if your setting is by default =0, then you probably will want to
add something like this to /etc/sysctl.conf:
hw.acpi.video.lcd0.active=1
So that on boot it gets 'enabled'.
