Laptop HP 15S-FQ
MB: DA0P5HMB8E0 Rev: E
EC 5570E

Witam kolegów
Nie mogę sobie poradzić z martwym laptopem, dlatego poproszę o pomoc w diagnozie.
Zalanie było na złączu baterii, oraz płytce z włącznikiem.
Po podłączeniu zasilacza bez baterii nie mrugnie nawet dioda w gnieździe zasilania, pobór prądu jest 0,025A na przecisku jest 3,3V spada po naciśnięciu do 0V - pobór prądu bez zmian.
Na cewkach brak zaniżonych rezystancji.
PL 1051 5V
PL 1101 3,3V
PL 1011 3,1V
Gdzie dalej szukać?
