It acts just like pushing the power button on the PC which puts the PC in hibernate mode, which takes around 30 secs on every PC I have ever had.
It sends the signal to shut down the PC within 5 secs, the PC is the thing that takes 30 secs to shut down.
Maybe some confusion we are not talking about XP's time to hibernate once button or pulse is issued we mean 5 seconds delay from PSU to issue pulse and then XP responds taking proper action. Some people and I have seen this from my unit takes as much as 30 seconds for the pulse or button push to occur from the M4. Normally the PSU delays 5 seconds before issuing the power pulse as part of the manufacture spec I assume to allow you to cycle the cars ignition and give the engine time to start. Same occurs on 12v off, it delays 5 sec then pulses mother board just like you pushed the switch. Then if set to minibox recommendation P1 it will wait 30 and power of the 5 volt rail which is always running on the PC normally with an ATX PSU. Not an issue in your house but would be a battery killer for your car.
All my previous version of their product work like this. Ign ON 5 sec later pulse form PSU and PC returns from Hibernation or shutdown. Then IGN off 5 sec later PC begins Hibernates or shutdown depending on how Power Mngmt in XP is set. I have never used any devise other than the M2 or M1 ATX. The PSU is supposed to be intelligent and offer this protection on its own. If you are still showing a 5V output after 30 sec with IGN off and the PSU set as to P1 as per documentation then your PSU is not working right.
XP's time to hibernate depends on how much resources you are using when requested, ram and swap the more you have the longer to write to a file. Also how fast your drive is a slower IDE will take longer to hibernate versus a faster SATA.
