Witam mam problem z laptopem G50-45, po wyłączeniu laptop już się nie uruchomił, przestał reagować na przycisk power. Po rozebraniu zauważyłem że jeżeli podłącze zasilacz to bardzo grzeje się układ PU401 za co on odpowiada? I co może być powodem jego uszkodzenia.

G50-45
ACLU5/ACLU6
NM-A281
Rev 1.0

Z góry dziękuję za odpowiedź i pomoc.

Podaj napięcia i rezystancję do masy z pin. 5 i 10 PU401.
Rozlutuj PJ403 i sprawdz, czy układ nadal się grzeje.
Duże prawdopodobieństwo uszkodzenia EC.
