Asus x450cc rev 2.0 no vcore voltages

[kalilinux25]

The laptop turns on led lights up but fan is not spining and no display checking on the graphics chip its getting hot on turn on so the board is starting but the processor is not getting voltages..


How can i fix this motherboard when it doesent have any vcore voltages ?
I dont have any reading in PL8004 +VGFX_CORE
and PL8001 +VCORE


Idont have any reading araud the PL8200 +VTT_CPU



I donthave any reading in SL5801 +1.8V PWRGD

if only +VGFX_CORE +VCORE missing flsh Bios with a working one first back up your Old one

Asus schematic very rare even when available we get problem since them have no label component on PCB.

Newest Quanta seem following them whose no labelling (apple, asus and samsung).

if u dont have schematic u must find vcore mosfets and trace its gate pins to driver ic

What is the resistance on coils to ground?
Lift the pads up and check again.
See if there's a short or only no output.

Short or no output.
If The chipset its dead thee still needs to be voltage on coils.
If there is non then is shirted or it doesn't output.

Ohms on coils

Thanks the problem was solve when I've change the vcore ic chip that supply power to the gpu and cpu thanks to all

Very good.
But you still need to understand the no voltage on coils vs shorted coils.
It's fast and life changing.
