Witam

Mam laptopa jak w temacie. Laptop nie reaguje na wlacznik. Napięcie na właczniku 3.3V po naciśnięciu 0V. Obecne napiecie na n.8 Winboard

25Q64JVIQ (U366) -> 3.3V na drugiej kości Winboard 25Q128JVPQ (U365) -> 0V. Przy podłaczeniu zasilania raz mignie dioda na CapsLocku.

Rezystancja na cewkach:
L66320 -> 6,4Ω
L66310 -> 6,4Ω
L60500 -> 77Ω
L60000 -> 110ΩK
L60300 -> 173Ω

Proszę o pomoc w diagnozie płyty...

Hello!
What does "ΩK" mean? Does it mean ohm (Ω) or kilo ohm (kΩ)?
