Lenovo IP3 NM-D471 No power
This board has no power. I have 20v on PQ5400 pin 5678. ACDRV on Pin 4 = 0V. Tested change charging ic BQ24780s, no result. Try change PQ5400 and PQ5401 also same. try bypass PQ5400 and working find. i got the power and laptop turn on fine. No short circuit find.
28 VCC = 20v
24 REGN = 6v
6 ACDET = 2.6v
5 ACOK = 0v
For ACOK, can i get it directly from REGN pin on charging ic? On the schematic, PR5436 and PR5437 has no component attached. so if i put 2 100k resistor to get 3v acok. does its ok? or maybe i should check other component?
