Nie wiem jak jest na tej płycie, dla pewności zabezpiecz oryginalny wsad.

PU5 wymieniony, KBC wymieniony.
KBC zaprogramowany wsadem z backupu i innym wsadem.
Nic to nie dało, płyta cały czas zachowuje się tak samo :(

Podłącz zasilacz i podaj na n.5 PU5 3V z zasilacza serwisowego prąd ustaw na 50mA, sprawdź jaki będzie pobór.

Na głównym zasilaniu nic z prądem się nie dzieje, natomiast na n.5 mam 50mA, 1.6V i wykryte przeciążenie.
