Dell Inspiron 15 3542 i3 no power no charging no led !!!!!

Hello
I have a Dell Inspiron 3542 laptop
when it is plugged into the charger, I have no power no LED indicator nothing ... just components that heat up in the motherboard.
Maybe I have a short circuit in the motherboard.
I disassembled my laptop. I downloaded the schematic: Dell Inspiron 15-3542 Wistron Cedar 13269-1 FX3MC.
Well, when I plugged the laptop into the charger, the PU4503 IC (TPS51225RUKR-GP) heats up too much (soo hot), and PL4501 and PL4502 warm up a bit.
please help me to find the shortcut.
Thank you .

You've isolated it to a bad mainboard - which needs to be replaced.  Unless you've got several thousand dollars' worth of test/repair equipment handy,  this is a replacement - not a repair.

If you do have such equipment, and the troubleshooting skills - you can try a repair.
