Based on the notes[1] I took, check the contents of /proc/acpi/wakeup
and look for something like "LID".  If nothing maps to the lid, then I
think it's either a hardware limitation or a kernel ACPI bug.  If it is
listed, but not marked "enabled", this is a software error (though I'm
not sure where exactly).
