Jetson TK1 does not booting up

Hi all,

I went through some of the topics in this forum and Found a clue on resetting the power state after a few hours is following

Basically the 0.014F capacitor is keeping +2.5V_AON_RTC signal high for hours to keep PMIC’s AC_OK (pin to indicate that the AC adaptor is present) high when cord is plugged out.

And also, I tried various jumper configurations in the Front panel J1A1 headers and

Noticed if I short circuit the 2nd and 5th header (GRN_PWRLED & blue color ground pin), TK1 startup without any issue.

But I’m not sure keeping that jumper forever could cause other problems?
