Witam, dostałem laptopa, który nie włącza się po zalaniu. Zalanie w okolicy złącza klawiatury.

Po podłączeniu do zasilania z wpiętą baterią (wypięte wszystkie taśmy) pobór na zasilaczu to chwilowo 0,1A i po 5 sekundach wskakuje na 1,74A, brak reakcji na włącznik.

Grzeje się rezystor zaznaczony na zdjęciu. Wymieniałem go ale nic to nie zmieniło.

Po podłączeniu zasilania bez baterii pobór na zasilaczu to 0.003A, brak reakcji na włącznik.

Pomiary cewek zaznaczyłem na zdj, tylko jedna cewka ma napięcie po podłączeniu baterii i zasilacza.

Kość BIOS brak zasilania, 8 noga 9,8kohm

Co powinienem zmierzyć dalej? Co sprawdzić?
