Q:

Auto-start after power off in nvidia TK1 board

I'm trying to make my Nvidia board (TK1) to boot automatically. i.e., when the power goes off and comes back again i want the board to power up automatically. I have tried the Nvidia forum and found a way to do it, but it works only when i manually pull the charger pin from the jack in the board and re-insert it. When the AC power is turned off (without pulling the plug from the board) and turned on again the board doesn't boot up automatically.
I want to know if it is possible to make a automatic switch circuit that would do the job of push button(which will replace the ON switch)
Note: I was also suggested to use a relay to make the button work, coz of it's bulkiness i cannot use it. 

A:

I have finally found the Answer to do this - use a comparator IC (typically a IC that would generate a reset if the input goes below a certain level). Found one in TI(TPS3700) - just the right one.
