First i am noob 
Second, i received this laptop, it was powering on but no display. I found that +1.2 v is missing. Then i found that +1.2V_S5 is shorted to ground. I removed and replaced RT8231AGQW and short was gone.
But...on PR1418 i have resistence 85 kohm and that resistor is 100 kohm. So i replaced it but again 85 kohm. Then i removed resistor and found out that resistence between those two lines (GND and +1.2V_VID) is more then 100 kohm, putting multimeter probes both way...but with resistor is 85 kohm??? how is that possible? i checked 5 times and resistors are good, outside circuit they show exactly 100 kohm.
Can someone explain to me how is this possible? thx
