Does your board work without R5193?
If yes, you may live as is.
But test it few days, sleeping, suspend, restarts...
Board is heavily liquid damaged, im working on replacing all that has corrosion and is not working, however when diagnosing R5193 came right off and the pads are gone, so no real way of knowing if thats the exact problem.
