Hi Derek

Yes, it seems I do have a problem. But it just got deeper. Now, I deleted the 
LID script, and copied the contents over to the powerbutton's script. Now, 
when I close the LID and OPEN, the computer does not sleep at all. It still 
dims the screen though, even though it has no script ran when it triggers the 
event. (Maybe it is a sign of a working APM???)
 Now, when I press the power button, the computer des go to sleep just fine. 
But for waking it up, I still need to close and open the lid. (Usually press 
the little lid pin only. I am guessing an event has to pass by, to wake the 
laptop up. If I press any buttons, it wont do anything. Only the lid wakes it 
up. However, when I shut down, it still goes to suspend twice. I have no clue 
what so ever.

I was trying everything possible,  believe me. From KDE, then using the power 
button (when it had the original script), and also from console using "halt" 
or "shutdown -h now" but all came back with the same results. Even if I stop 
acpid before shutdown, it still does the same deal. It makes me believe that 
while I used the lidbtn.sh for suspend on lid event, it recorded a bunch of 
events, and tries to catch up, and it has two chances upon rebooting, so it 
uses two suspends, and maybe once it goes away from cache, it will stop doing 
that? I think I at least suspended with the lid button 20 times if not more. 
That means it has about 20 events recorded in the cache that has not been 
executed yet. But shouldn't that clear when I reboot? I even removed the 
battery for a while, but it kept doing it.

Do you have any idea, where to go from here? i dont even use the lid anymore, 
but it's still suspending.
