Hi, I got a new Dell laptop (Precision M70). I would like to know how I can turn off the backlight of the LCD. The backlight doesn't turn off when I flip down the screen or when asked by xscreensaver. I've also tried the different sleep states without success. S1 and S2 don't seem to be supported and I get "acpi0: device_suspend failed" when I try S3 or S4.
