Model : Lenovo Ideapad 320
Board id : DG425 DG525 DG725 NM-B321 Rev 1.0 2017-03-14
Laptop came with blown mosfet PQ2203. I replace with good mosfet. Now laptop is on but no display. There is no voltages on PL2201 and PL2202. EC_VR_ON has 3.3V. All other coils have proper voltages. Resistance between PQ2203 mosfet pin 1 and pin 4 has 5.5 Ohm. Is layer problem?
