Czołem,

Płyta jak w temacie. Pytanie mam do bardziej doświadczonych kolegów: Czy powyższa platforma włącza się bez sprawnej baterii? W komputerze na pewno uszkodzona jest bateria. W obsadzie płyty brak PU44C1 (+3D3V_VDD_DCIN). Przy zasilaniu z gniazda DCIN1 PU4301 otwarty, PU4415 zamknięty (przewodzi przez diodę) zatem +SDC_IN i 20VDCBATOUT obecne. Przetwornica PL4401 nie działa, brak również ACOK z ISL9538CH (układ podmieniany). Płyta uruchamia się normalnie po zwarciu S-D na PU4403, uruchamia się również normalnie po podaniu napięcia 11V na zaciski baterii, jednak DCIN pozostaje nie obciążony (ok - brak komunikacji z baterią uniemożliwia włączenie ładowania) Wg. schematu (ściągnięty z forum) do pracy konieczne jest 3D3V_AUX_S5 generowane przez PU4501, ale do jego pracy potrzebne 19V_DCBATOUT.

Pozdrawiam
Piotrek

Co do usterki, to nie pomogę, ale z całą pewnością mogę potwierdzić, że działa bez baterii.
