So when suspended, it's possible that the laptop will wake up during transport

When the lid is closed, the power button should be disabled as an ACPI wake up

I obviously forgot to mention that the laptop was a Dell Latitude D420
Is this even possible? It's also probably better to do this from HAL since you
want all the quirks in one central place...
The power button doesn't do anything when the lid is closed. Fixed in hardware!
