Prośba o identyfikację elementu o oznaczeniu 4GD.

Po wymianie wskazanego ic laptop ruszył ale działał tylko gdy usb-c było wpięte jedną stroną, obrócenie wtyku o 180 stopni powodowało przywarcie. Przy wskazanym układzie są dwie diody zabezpieczające linie komunikacyjne. Jedna z nich miała 240 ohm. Po wymianie wszystko działa jak należy.
