If it is implemented, where can I find them and how to use it? It's a "hardware" event. Surely ACPI isn't strictly involved. I read this as meaning that ACPI mustn't interfere with such function. Certainly my Dell Inspiron will shut off when I hold the power button down for 4 seconds without generating an ACPI event. ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
