Witam,
jak w temacie - pacjent nie włącza się. Wszystkie podstawowe napięcia obecne, bateria ładowana normalnie.

BIOS przestawiony - bez zmian.

3V na włączniku obecne, po wciśnięciu spada na 0V to samo na RI501, RI502 i n1. CE21. Następny element w kolejce to KBC IT8227VG-128, czy to tu będzie problem?
