GPU: gn20-p0-a1 (RTX3050)
EC:IT8227E-192
EC2: ITE8176FN-56A
BIOS:74m12jwsiq

Laptop po podłączaniu oryginalnej ładowarki sam się uruchamia sygnalizując diodą zasilania oraz pobiera 0,50 A, brak różnicy z RAM i bez.
Po przytrzymaniu przycisku power laptop się nie wyłącza tylko resetuje (na chwilę przygaśnie dioda power).
Po podłączeniu ładowarki 65W w gniado USB-C PD nie przełącza napięcia z 5V na 20V
Brak poprawy po dociśnięciu CPU/GPU
Napięcia na cewkach:
PL6202 - 5,1V
PL6201 - 3,4V
PL3001- 1,2V
PL5401 - 0V (bez baterii)
PL7701 - 0,762 mV
PL6601 - 1,8V

+1.8VS - obecne
+3VS - obecne
+5VS- obecne
+0.75VS obecne

Wgrywałem różne wersje BIOS i na każdej zachowuje się tak samo, jak i z wylutowaną kością BIOS.

Proszę o pomoc.
