What is the resistance to GND Bios pin8, what voltage is missing on the coils when you power the MB

Re: HP Notebook - 15-ay019ca

i have 19v, 3.14v near battery charger, 3.2v on power switch, all other volts are missing

Re: HP Notebook - 15-ay019ca

the resistance to GND Bios pin8 = 10.6 ohm

The resistance is very low, try to find why.

Check SIO pin 110 75 37 112 is the +3/+5 VALW line is ok ?

Re: HP Notebook - 15-ay019ca

pin 110 75 37 112 are all 3.2v

Re: HP Notebook - 15-ay019ca

+3/+5 VALW line is ok ?and EC_RSMRST# before you press the power button after you press the power button Voltage?

With this resistance, chances of pch being bad is very high.
