Laptop trafil do mnie z grzebanym mostem oraz biosem. PCH wymieniłem, bios podmieniłem ale niestety brak reakcji na włącznik, jest 3v na nim. Na cewkach 3v, 5v obecne, reszty brak. Nie znalazłem zwarć

Po podpięciu zasilacza pobór prądu 0,04A, lekko grzeje się pch

Rezystancja jest wysoka. Bios wymieniałem już wcześniej 2 razy, niestety ten który był raczej nie jest oryginalny. Czy masz jakiś pewny wsad do niego?

Próbowałem czyścić ME Region ale ME Analizer nie może odczytać tego pliku "Found unidentifiable Intel Engine firmware" czy jest inny sposób w tych laptopach?
