Description Manu Thambi 2004-10-14 23:41:43 UTC 
Distribution: Fedora Core 2  
Hardware Environment: Dell Inspiron 4000 laptop 
Software Environment: doesn't matter 
Problem Description: When changing the system state to S3, it suspends but the 
screen is left on. I think the backlight fails to turn off. The laptop wakes 
up from sleep properly. The same behaviour is shown whether we do this from X 
windows or the console. 
Also, while in X, "xset dpms force off" works correctly and turns off the 
display. 
 
Steps to reproduce: 
boot the system. 
echo mem > /sys/power/state
