MBA Won't turn on. Completely dead. See a resistor missing inside.
Friend was about to toss a 2011 11” MBA because it was dead and they thought not worth repairing (won’t turn on and charger light also off when connected) . I opened it up and noticed there was residue on the logic board (see red square) and that this round item, which I’m guessing is a resistor, is missing (see red circle - 330). Comparing it to my MBA, which is nearly identical, I see no other missing pieces/differences.
Might anyone know what this part is/does and if replaced, could this potentially be the solution? Also, would replacing the logic board possibly get the laptop back up and running? Asking this second question because I’m wondering if I remove my logic board to test, would this be safe, or might I be risking my own as well (would only swap out to test this missing piece out).
Questa è una buona domanda?
