The bug is still present in NP900X3E-A02US, BIOS version P07AKB.
Resetting with a pin fixes the problem for the short period, usually until charger is plugged a few times.
Comparing the dmidecode output in the "fixed" and "broken" states shows only one line difference:

"Fixed":
Wake-up Type: Power Switch

"Broken":
Wake-up Type: Other

My sister has an NP900X3C with windows 7 installed, and that machine has no problems with lid or charger events. I suspect windows samsung drivers somehow reset some internal switch after system wakeup. I could do some tests on windows machine, but I just don't know how to debug system drivers.
