Being a bit late... From my experience, the windows guest does
recognize ACPI signal when one of two conditions are met: the signal
was sent *twice* in a short period, or you had issued C-A-D on the
standard input before. I do not understand why the Microsoft did
things exactly this way, but that`s how it works (or may work).
