Witam, mam płytę główną od ASROCK Q1900-ITX R1.04. Bardzo proszę o pomoc w identyfikacji elementów zaznaczonych na czerwono. Oba elementy są takie same i na obu jest uszkodzenie ale mimo to odczytałem coś w stylu g4e0G ale nie wiem co to jest i czy poprawnie odczytałem.
Gdyby ktoś posiadał jakiś schemat/boardview byłbym wdzięczny.
Pozdrawiam

Q748 = Q814 = QM2423K (P-MOSFET). Jeśli oba zostały uszkodzone, to do sprawdzenia headery USB1_2 oraz USB3_1_2, a także gniazda i kable, które są do tych headerów podłączone (pod kątem zwarć pinów).
