    • Before starting this procedure, you should disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide to disable Auto Boot.

    • If your MacBook is running Big Sur v11.1 or later, disabling Auto Boot may not work. You can proceed normally, but make sure to disconnect the battery as soon as you're inside.

    • Completely power off and unplug your MacBook before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 driver to remove the following screws:

    • Two 7.9 mm screws

    • Two 7.3 mm screws

    • Six 2.6 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your MacBook.

结论

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

Ich hatte einen Wasserschaden und seit diesem funktionieren die Lautsprecher nicht mehr. Es kommt kein Ton raus aus beiden Seiten. Zunächst hörte ich noch das Neustartgeräusch. Nachdem ich aber den dann Laptop auseinandergebaut, getrocknet und wieder zusammengebaut hatte kein Ton mehr. Die Lautsprecher selbst wurde allerdings nicht wirklich nass. Kann die Audioplatine hier die Ursache sein und ein Austausch helfen? Die anderen Funktionen, wie Touch-ID, die über die Audioplatine laufen, funktionieren allerdings noch. Gibt es sonst noch ein einzelnes Bauteil oder Kabel, welches dafür verantwortlich sein könnte?
Ich gehe davon aus, dass die Lautsprecher an sich noch intakt sind.

Richard,
Entschuldigen Sie zunächst mein schlechtes Deutsch. Es lohnt sich wahrscheinlich, die Audioplatine auszubauen und anschließend zu reinigen. Verwenden Sie zum Reinigen der Anschlüsse >90% Isopropylalkohol und eine weiche Bürste wie eine Zahnbürste. Auf sichtbare Korrosion prüfen. Konzentrierte sich der Wasserschaden auf die Nähe der Audioplatine? Ich glaube nicht, dass Wasser den Lautsprechern Schaden zufügen würde, es sei denn, sie würden in Wasser getaucht, oder dass das Wasser speziell ihren Stecker beschädigt hätte. Viel Glück bei deiner Reparatur. Ich bin gespannt, ob Sie das Problem lösen.
