#1 MSI GF63 Thin 11UC, ms-16r61 martwy

Płyta: ms-16r61
CPU: SRKT1
GPU: GN20-P0-A1
PCH: SRKMA
KBC: ENE KB9548GF2

Laptop trafił do mnie martwy, ze zwarciem na +1.8B (PL13).
Wymieniłem most PCH, wyczyściłem ME w biosie. Rezystancja PL13 wzrosła do 1.7 kOhm.

Po podłączeniu zasilacza płyta nie reaguje na przycisk, jest martwa. Pobór prądu to 0.08A. Jedyne co się lekko nagrzewa na płycie to PCH, do 26°C.

Na kości SPI 3.3V obecne. Na przycisku power 3.3V obecne.

Pomiary:
PL9 = 3.3V
PL8 = 5V
PL13 = 1.8V
PL16= 1.8V
PL18 = 0.29V (bez baterii, z baterią 11.5V, laptop poprawnie ładuje baterię co sygnalizuje diodą)
PL2 = 1.8V
Choke2 = 0.99V
Pozostałe cewki: brak zasilania

Rezystancje:
PL9 = 2.2kΩ
PL8 = 2.5kΩ
PL13 = 1.7kΩ
PL16 = 693Ω
PL18 = 45kΩ
PL2 = 67Ω (1.8V CPU)
PL3,PL4,PL5,PL6 = 14Ω (Zasilanie CPU)
PL10,PL11 = 0.4Ω (zasilanie GPU)
Choke1 = 82Ω
Choke2 = 957Ω
PL14 = 38Ω
PL20 = 1.4kΩ
Pierwotnie myślałem, że sprzedano mi wadliwy PCH, zamówiłem więc drugą sztukę od innego dostawcy. Po wlutowaniu zachowanie płyty jest identyczne.

Proszę o pomoc w znalezieniu usterki. Nie znalazłem nigdzie schematu ani BV do tej płyty.
