I run 5.3-RELEASE on a ThinkPad X31. Using ACPI, with acpi_video loaded at boot time (as verified by kldstat), I find no dmesg output for the acpi_video driver; it would seem the driver cannot attach on the X31. I believe I need acpi_video so that my backlight turns off when I suspend; at present, when I transition to state S3, the machine suspends successfully (no disk noise; "moon" icon illuminated), and while the image on the display is blanked, the power-hungry backlight remains on. Has anyone with an X31 (or other ThinkPad) found a fix or workaround? Thanks, -Brad, bkarp@cs.cmu.edu
