I have it on my T30 and I have seen others with different brands and models report it. I don't have a fix at this time. (Since I don't work on ACPI code, I won't be finding it,) The work-around is to use apm and not ACPI. To switch to APM, edit /boot/loader.conf and add: apm_load="YES" Edit /boot/device.hints and add: hint.acpi.0.disabled="1" and change the value of hint.apm.0.disabled to "0" Make sure that your rc.conf contains: apm_enable="YES" Once that is done, you should be able to turn off the back-light any way you could under V4. Hopefully APM will continue to mature and these issues will get settled over a bit of time. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
