Default Dell Inspiron 13 5378 2-in-1 not turning on

Hi all, working on this Dell Inspiron 13 5378 2-in-1 (Logic board Starloard13_R 15296-1). I get stable 3.3v on its inductors & 5v on the other inductor. I checked the ON/OFF micro switch & it works fine & I get 3.3v on one of the pins. BIOS voltage are even good but it does not turn on & no fan spin. Re-programmed a new BIOS chip but no luck. No Liquid damage anywhere on the motherboard, all clean. Shorted the on/off pins from the main board it & still no activity. Does anyone know the cause of this, why does it not turn on? Does anyone have the Schematics for this motherboard? Thanks

Check if you have all standby power rails, check for shorts, try to hold the power button for 30 seconds see if it helps .


Is your Super IO chip okay?
Check RSMT/Reset resume if high, use the oscilloscope to check for data on the bios chip
