Witam

Płyta z Asus-a GL553VD startuje bez obrazu. Nie nie ma napięć na VGA NVIDIA. Brak sygnału AON_PWR_EN -> VGA_PWR_EN. Sygnał ten wystawiany jest przez PCH (sygnał załącza napięcie +1.8V i dalej przetwornice dla grafiki nvidia). Na płycie wymieniany był KBC (przelutowany z innej płyty - nie jestem pewny czy na 100% sprawny) + charger po tych podmianach płyta startuje jak wyżej. Pytanie do osób, które znają tą platformę czy PCH generuje sygnał AON_PWR_EN na podstawie sygnałów z KBC czy z innych źródeł. Zastanawiam się nad podmianą PCH druga opcja to wymiana i programowanie KBC.
