Startup/shutdown conditions from the IGNITION signal :
1. IGNITION startup signal must be valid during 10 sec. (anti noise protection).
2. IGNITION shutdown – IGNITION signal must be inactive during 5 minutes, then PIC
controller initiate Power Button signal (OS must be set to shutdown from the Power
Button). It generate Main Button shutdown event and then goes to complete power
off.

is disconnected from the power source.
The system can be switched off from:
1. Power IGNITION OFF signal.
2. ACPI OS shutdown
3. Power Button - generate ACPI event (OS Dependent)
