Part of the components covered by a sticker
Inside the 13" MacBook Pro with Retina display Late 2013 there is a part close to the battery with some chips that are covered with a sticker and a warning message. I guess those are related to the battery but could not find anything specific.
After a liquid spill I have cleaned the logic board but the battery is not working and I suspect it could be because it is very sticky on that part (it was Coca Cola, terrible)
Is it safe to clean that part with alcohol as I did with the rest of the components or better not to touch it in any way?
Ist dies eine gute Frage?
