HP OMEN : DAG35DMBAD0
NO power ,no short ,no corrusion
Consumption : when charger plg in = 0.004 amp

Only 3/5 vl are present when charger connected..when i put my red probe at the coils of 3/5volts and power on with my power suplly it try to rise than 0v.
when try to power on using power button i note this starnge value : 3v then 0.300v then 3v !
No light at power button led

All coils resistances :
Pl 2001 =3v measured with kohm.
pl 2004 = 5v measured with kohm
pl 6001 = 49.7ohm
pl 4012 = vccsa = 24.4 ohm
pl 3001 =...

It's the main bios , we ask you for the EC bios , the 16MB chip...

This laptop won't power on , when power supply is on it takes 0.001 , button trigger on it becomes after a couple of seconds 0.061 amp..and nothing
No heating (Of COURSE) , no short to GNd at all coils present , 3/5 valw is present , 3/5 vl present.

With the power plane , at state 4 +1.8VALW and +3ALW_PCH must be present but no one due to enable signal is missing .
when button trigger on , 3v dow to zero than 3v , the super io send BTN_OUT#_R to pch but no rsmrst ..0v.
i follow his line , no short .

Good news
Can you please share the BQ voltage...

If there's no short at your motherboard , all coils are not shorted so i suggest to concentrate more at BQ24780S.
This forum is full of informations about it.
from my opinion , if i had 19v at pin 28 / 2.7v at pin 6 / 6v at pin 24 ...so i must find my 6v at pin 5 ( ACOK is pulled up to 3VL rail and not 3VALW rail in general )...and there's no short to gnd at BQ pins....so i change it simply .
ACOK must be 6V in this case get it from BQ24780_VDD

Is PR112 /PR111 populated at this motherboard !!

PR100 resistance to GND to know if there's a short at 19v rail
you can also check all colis for short

what do you mean by : when I short it out the laptop powers up....is there a display !

Many others measurements to take.
PQ101 is it OK (Diode mode)
PR100 measure with resistance mode
