Actually, I have the same problem. I was googling for it this
afternoon and found references to acpi_video, but settting the
video.lcd0.active sysctl to =0 would output "...lcd0.active: 1 -> 1"
and consequently do nothing. LCD remains powered.

Found users reporting this problem, but no solution to it.

I'm running 5.3-BETA7 (cvsup'd yesteday).

HTH, Thanks,
