Dell G7 LA-E994P not start after water spill

[ktmmotocross]

Hello.
Have this Dell G7 LA-E994P that after water spill and cleaning did not start.
It was get to me from other shop that clean corossion, but i dont know where.

Board have 3.3V, 5V, 1.0V, 1.8V but no RAM, CPU, GPU power and on GPU coils i measure 0.2ohm to ground, but even after removing gpu coils nothing changed. power switch works ok, but i try to measure which pin on KBC is PWSW but cannot find it

Dont have schematic

0.2Ohm are very very low. You measured on which side is the short after removing the coil? What did you tried, to convert it to UMA?

Resistance to ground lower than 1 ohm is normal on VCore of NVidia 1000 series and newer. Hard to say what's actually a short to ground and what's not.

PIN127 of kbc is power sw_in and there is no power button on this kbc. You need to trace the resistor connected to pin 127 of kbc. The other side of the resistor is power button and powerbutton on this mb is powered by RTC.

Is the laptop charging the battery?

NO. have 0.2V on battery. data lines have 3.3V
