Bardzo bym prosił o pomoc w ustaleniu usterki z laptopem jak w temacie. Płyta NM-C931 z procesorem i7-10610U, 16GB RAM wlutowanu + pusty slot, dołożony modem lte. Laptop zawiesza się po uruchomieniu systemu windows lub też podczas uruchamiania. Zdarza się, że brak obrazu ale rzadko. Podmieniane były dyski i instalowane systemy na nowo. Dzieje się tak w każdej konfiguracji sama bateria, bateria + zasilacz, sam zasilacz

Hello!
Is this measurement correct? Please, check it.

If the measurement is fine, remove this coil from the board and measure the resistances to ground on both pads on the place of this coil.
