Help identify smoking element on 820-3115-B logic board

"My friend" peed on their laptop and I tried cleaning it with a toothbrush and 91% isopropyl alcohol. After connecting the battery, the circled component sparks/smokes. I need help identifying this components and any useful information to fixing the issue would be helpful. I included images of the blown component and the logic board before I washed it. Thanks for any help!

@chrisp5 that is a bit hard to make out. Right now it looks like C9415 which is a 4.7UF 25V 10% X5R ceramic capacitor in a 0603 package. A clearer and lighter picture should verify this.
