Witam, mam problem z Lenovo 5 15ACH6H, który po podpięciu oryginalnego zasilacza i przyciśnięciu przycisku POWER zaświeca diodę POWER ale nie wyświetla obrazu. Brak większości napięć na cewkach po włączeniu POWER:

Poboru prądu nie mam na razie jak zmierzyć ponieważ na moim zasilaczu laboratoryjnym jest całkowity brak reakcji i brak poboru prądu - podejrzewam, że tu jest wina mojego adaptera. Czy można w jakiś sposób uruchomić tę płytę przy pomocy zasilacza laboratoryjnego np. wlutować dzielnik napięcia do pinu ID gniazda zasilacza?

Pomiędzy masę a środkowy pin (ID) wlutuj rezystor 4,7kΩ - to powinno zasymulować zasilacz 230W.
