With the help of a fine tool we separate the casing from the chassis around its entire contour until it is separated

We remove the protective adhesive and expose the battery connection with the help of a soldering iron, we release the soldering points that join the battery to the motherboard

We extract all the adhesives that hold the speaker cable once removed, we desolder the speaker cables located on the motherboard once they are loose, we extract the two Phillips-type screws (PH # 00) that hold the speaker and we can extract it.
