I started having this on my SAMSUNG NP530U3C-A05EE machine this September (or at least I did not notice it before, although I had been using it with Quantal since June). Decided to upgrade to Saucy, however this did not fix the issue for me. No ACPI event is triggered after connecting/disconnecting the AC cable and/or closing the laptop lid.
Booted into Windows to see if there is a BIOS update avaible, as suggested by someone here, alas nothing has been provided by SAMSUNG so far. (And I do not believe it will be.)
