HP OMEN AX236TX DAG35DMBAD0 rev NO power no light.
Hi ,
This is another laptop with same problem in which there is no Power to the system while when checked for first two mosfet switching (19v rail area).
I am getting 18.2 volts at the gate of first mosfet PQ1002 and it is a P-channel mosfet.
PQ1002 first mosfet:
pins 1,2,3=19volts , pin4=18.2 volts , pin5,6,7,8=19volts
PQ1002 gate is controlled by PQ1004 voltage divider circuit , if we calculate for voltage at gate of PQ1002 it should be around 15volts (due resistors 220K,1M) but i am getting 18 volts.
PQ1003 second mosfet:
pin 1 ,2 ,3=0 volts , pin 4= 0 ,
