#1 Dell XPS 15 7590 brak reakcji na power


by PitD 14 May 2024, 11:49
Laptop Dell XPS 15 7590
Platforma: Compal EDP51/EDB51 LA-H331

Brak reakcji na power
Na cewce PL 400 72Ω
Po podaniu z zasilacza serwisowego 3.3V pobór 0.24A
Czy na PU400 pin 12 powinno być 12.6V czy całe napiecie zasilania?

Po pozostawnieniu na dłuższą chwilę zasilacza grzeje sie PCH.
Czyżby do wymiany?

Bazując na schemacie, powinno być tu napięcie, występujące na stykach baterii - wartość zależna od tego, czy komputer pracuje z baterii, czy jest podłączony do ładowarki.

Zdecydowanie nisko jak na tę linię zasilania. Niestety, wygląda to na uszkodzony PCH.
