For those of you with a Samsung laptop showing this problem, please see
this issue:
https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061
in particular my last two posts.
I think a kernel patch can be made to flush the events (LID, AC
plug/unplug, etc) from the Embedded Controller, at resume, in the same
way that I do it with my C program that I attached to that issue for
Samsung laptops (and maybe others with the problem).
TL;DR: If the events don't get flushed (queried), the GPE of the EC is
never triggered again (chicken and egg situation), my little program
queries the events and "unstucks" the EC immediatly.
After that, LID and AC plugged events are reported normally.

Title:
[Samsung NP530U3B-A01UK] Laptop does not suspend on lid close
Status in The Linux Kernel:
Incomplete
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I've installed Ubuntu 12.04 on my wife's laptop, (a Samsung NP530U3B), all
goes well except when I close the lid it does not suspend. I've checked the
settings and it is set to suspend on lid close, though does not. Things I've
noticed are:
1 - Clicking suspend in the power menu works fine.
2 - When I cat /proc/acpi/button/lid/LID0/state it always returns open, even
when closed, (I ran a script that looped the cat then closed the lid)
3 - Running the latest Ubuntu 12.10 alpha 2 does not work either.
4 - The latest mainstream kernel
'linux-image-3.5.0-999-generic_3.5.0-999.201207190406_i386' does not work
either.
5 - One odd thing was that after installing the latest bios on the laptop
using Windows 7, then restarting into Ubuntu worked once, then it never worked
again. I tried booting in to Windows then rebooting back in to Ubuntu to see if
that is what changed something but it did not work that time.
