    Asus G752VT Touchpad cap heated up and smoked, is it fine to keep using motherboard?

    A badly damaged 80C 30V cable for the touchpad heated up a capacitor on the motherboard and it got red and smoked. I tested the touch pad with a different cable and it still worked. Laptop is a Asus ROG G752VT, if anyone has an idea what these caps are I'm willing to reflow some new ones since I have a reflow hot air gun and a little bit of experience. The schematics are next to impossible to find so im not sure what caps would be needed to be replaced.

    Cable that was damaged and caused voltage spike

    Caps that got burnt a little, the smaller cap wasnt reading anything in diode mode and the bigger cap was reading .223

          I don't know what size you need, but anything with 0.1uf / 100nf will do which is over 20v

            Heres another side picture, shows a better angle. They seem to be two different types

              Likely burnt the inductor not the capacitor.

                Should I leave it as is?
