Help: HP Spectre Convertable Power IC Identification

[vexarvf1s]

I am trying to identify what I think is a buck-bost chip that creates what might be 3V
There are no markings on the board.
Any help is much appreciated.

This is the computer info:
HP Spectre X360 Convertible
Model 15-eb0043dx
Product ID: 9GB29UA#ABA
Mainboard: DA0X3BMBAF0
MB Part Number: L95650-601
MB Description: MOTHERBOARD DSC MX250 2GB i7-10510U 16GB WIN

What I have done to diagnose and testfor the problem and why I think it is this chip:
Mainboard will not POST or turn on when power button pressed.
With the power cord plugged into the computer I get a battery charging LED, Amber/Orange when power plugged in with battery.
USB voltage check shows 20V going in and 2+ Amp draw with battery plugged in.
Main Voltage rail does not look to be shorted as expected since battery looks to be charging.
Searched coil voltages and found 5V rail, but the coil/rail next to it was only giving 0.1mv
I would expect this to be my 3V rail.
Under a thermal camera I can see the chip responsible for making this rail's voltage is getting hot, unlike the 5V.
It also looks like it is trying to start, but fails then tries again. The chip heats up then cools then heats up again.
Measurements:
Coil on the output measures 0.346 in diode mode
Input voltage is 13.21V
Missing 3V on what might be gate, diode mode 0.596?
4.97 volts on what might be power good?
No voltage out.

Again I am trying to identify what I think is a buck-bost chip that creates what might be 3V
ID markings on the chip are L8=7G then P0C

Any chip with xx= is Richtek. L8= is RT6256BGQUF. QUANTA X3A DA0X3AMBAG0 schematic uses the same chip for reference.

More likely to be a load issue. Direct resistance checks sometimes are misleading, as a short can be after a diode or load switch.
