First of all we must extract the tray of the cards.

Remove the two Pentalobe screws (TS1), and with the aid of suction cups and a fine tine, we will uncouple all the edges of the casing, so as not to damage the casing we can change the metal plectrum with plastic ones.

We remove the four Phillips screws (PH # 00) that hold the speaker module, and with the help of a flat tool, we will detach it from the chassis.
