see attachment. The first two lines are with the open lid, and the 
second two - with closed ( not sure why each line is printed twice - 
I only did cat ...LID/state once for each case );

hope this sheds some light.

Also I checked the problem with absence of AC events - acpid is not to 
blame: I stopped it and did cat /proc/acpi/event, and then 
unplugged/plugged AC, but never saw any events ( if i push lid button 
events do show up).
