What are these mystery black SMDs?

My friend spilled wine on her laptop and a bit has managed to get onto the logic board. The only place that I can find where it has touched the board is directly on the SMDs circled in the link below, and maaaaybe a teensy bit on the cluster of circuits next to them. I've given the entire board an isopropyl alcohol bath and scrubbed all the corrosion off, rinsed with distilled water and one more alcohol bath before letting dry in a dehydrator. In the event that it still doesn't power up, does anyone know where I would be able to find these SMDs online, or what they even are? There are no markings except for "68 C15" printed on the top.

Is this a good question?

Should also mention that the laptop is an early 2011 macbook pro 15"

Those bigger shorted components are both capacitors and could be found online at various components sellers such as Mouser, Farnell or Digikey. Would need a wider angle picture to help you identify them exactly.

No problem! Here is a wider photo


These two are both capacitors, 68µF ±20% Molded Tantalum Polymer Capacitor 16V, 50 mOhm in a D2E-SM Case.

Just copy+paste and you'll easily get them.


thanks so much!


No problem, good luck with your repair, hope you succeed to get it back to full working order.


One more question since you seem to know a lot about the individual components you know what that black chip is directly to the right of those two capacitors, and in your opinion, do you think that would need to be replaced as well? Looking back at the picture, it looks like some electrolytic fluid managed to touch that part..
