#1 Lenovo V310-15ISK nie działają gniazda USB

Płyta główna DA0LV6MB6F0 rev:F nie działa gniazdo USB 2.0 natomiast gniazdo USB 3.0 jedno działa a drugie nie zawsze.
Znalazłem przywarcie na szynie D+ lub D- przy gnieździe USB 2.0 jest tam 66Ω.
Niestety nie udało mi się znaleźć schematu i nie wiem czy szyna danych idzie od razu do mostu czy przechodzi przez jakiś element. Może ktoś z was miał podobny problem?

Hello!
The USB data lines goes straight to the PCH part of the APU hybrid almost for sure.
99% it is bad APU hybrid.

To be 100% sure you should remove the APU from the board and check the resistances on USB data lines again without APU chip.
