Witam Kolegów
MSI GF-66
płyta: MS-15811 ver 2.8
CPU: SRKT3
GPU: GN-20-E3-A1
PCH: SRKMA
BIOS: 25L25673G
KB95480F2

Laptop trafił do mnie po zwarciu na USB3.0 (podobno)
W każdym razie laptop przy próbie włączenia pobiera 80mA na ułamek sekundy jest skok do 0,3(0,4A) ale to tak krótko, że miernik w zasilaczu nie zdąży pokazać wartości i wyłącza się.

odlutowałęm cewki CPU na cewkach zwarcia nie widzę od strony zasilania
jednakże od strony CPU mam poniżej 0,1ohm... do masy sądzę że umarł CPU ale może to normalne dla tego modelu.
Zwarcie mam zarówno na PL5,PL4,PL3,PL2 (około 0,08 ohm do masy)
I na grafice PL9,PL10,PL8, PL11 (około 0,25ohm do masy) na

Mój miernik nie pokaże dokłądnie ile ale na cpu praktycznie zwora.

Ale pytam Kolegów ile na tych cewkach do masy mniej więcej powinno być

Mam taką samą płytę na serwisie (zwarcie na zasilaniu ekranu, płyta uruchamia się na zewnętrznym monitorze) i u mnie z procesorem SRLD1 rezystancja wynosi 4,5Ω. Zatem przy takich wynikach pomiarów (poniżej 1Ω) zdecydowanie linia VCC_CORE jest zwarta.

Inne rezystancje:
- CHOKE5/6/7/8: 0,2Ω
- CHOKE1/2: 48Ω
- PL2/3: 10,5Ω
- PL9: 87,5Ω
- PL23: 13,8kΩ i rośnie dalej bardzo powoli
- PL22: >20kΩ i rośnie, czasami spada
- PL21: 1,35kΩ i rośnie dalej bardzo powoli
- PL20: 2,9kΩ i rośnie dalej bardzo powoli
- PL19: 158Ω
