I have already confirmed the multimeter reading and it is reading correctly. It could be that the 7v is peak.
I had already checked the feedback circuit and the resistances are fine but I didn't measure the voltage because as soon as I saw 7v I immediately turned off the power.
What is the right way to measure the circuit without the risk of burning consumers? just lift the coil from the 3v line?
I have to confirm the pc8724.
Regarding frying the circuit, I tested the ground resistance on all the power rails again after turning off and they are ok but I don't know how much...

Good afternoon everybody.
I would like to ask for help identifying a problem that I will describe below.
Asus gl504gm laptop
Won't power on
When connecting a power supply to the input, it does not turn on and consumes 5mAh, but if you connect the battery, the battery voltage is present and when you press the power button, it starts without an image with:
pch- 1v
3.3vsus - 7v
5vsus - 5v

tps51285a is new
pch was changed
3.3 mosfets replaced
1.2 controller replaced as well as the respective mosfet.
No power supply has...

Hi everyone. My name is Martins.
I found this forum while looking schematics for ASUS laptop (Gu502SV).
Thank you all for the precious help.
