I'm seeing the exact same behaviour as Alistair on an NP530U3B. The curious thing is that after pressing the magic reset button all works well for a while. Under Linux the lid switch works, the laptop sleeps just fine and nothing I can do seems to break it.

A day or two later, it mysteriously stops generating ACPI events (according to acpi_listen) and it take a press of the reset button to get it all working. Really hard to debug and although this behaviour is consistent, I can't quickly reproduce.
