booting. The Ignition state will be latched for 60 more seconds so that the motherboard will
have a change to come up in a clean manner.
3) Ignition=ON. Your computer will remain ON.
4) Ignition=OFF. M2-ATX waits for "OFFDELAY" in seconds (see jumper chart) and then it turns
the motherboard OFF by sending a signal to the motherboard's ON/OFF switch. Your
computer should turn off gracefully (shutdown procedure). After shutdown, 5VSB will still be
provided for another "HARDOFF" seconds. In the event where the shutdown process is
longer than "HARDOFF" (Operating System gets frozen, etc), power will be shut down hard,
turning off all power rails. During the HARDOFF procedure, the battery levels will be
constantly monitored to prevent deep discharge situations.
5) M2-ATX will go to step 1, if ignition is tuned ON again.
