#1 dell 3721- nie zawsze się uruchamia

Płyta: LA-9105P laptop czasami się nie uruchomi pobierając 200mA i grzeje się mosfet PQ101 po ponownym włączeniu płyta się uruchamia poprawnie.
Podmieniłem mosfet lecz problem dalej pozostał. Znalazłem podejrzany kondensator lecz po wymianie dalej jest problem. Nie wiem jak namierzyć uszkodzony element, ma ktoś jakiś pomysł?
