hi, i have issue with laptop ,power button 2.6v on coil 3.3v alw 0,7v on 5 alw 0v ,LDO is present 3v and 5v en 3v, +3VPCU_KBC is present ..I change new multicontroller same ..I could not flash multicontroller by vertyannov programmer ,also old one and new one..Maybe multicontroller new is fault,or I miss something more?Pch is 0.20ohm ..Thanks in advance

Очень низкое сопротивление на питании PCH.
это не нормально, искать причину

Что-то должно греться...

No,short at all,I inject voltage,on lab power supply 20v 0.1A

on PCH is 0.60 ohm ,i dont have 3 alw and 5w no short i change RT6575D sp_on is present +3vpcu is present..

check Y2 32.768KHz. check all PL and write here Ω, check LDO3 & LDO5

I dont have oscilloscope i cant test frequency

Very strange,I have on coil 3.3alw(0.7v) but on power button 2.6v +0.7v=3.3v ,like liking voltage ,I can't understand why,I change multiconntroler..
