To start we must apply heat to the back shell, in order to soften the adhesive that holds it, and with the help of a thin enough metal tool, we will open a small one through which we will introduce a plastic spike, with which it will be less likely damage the case, and we will take off all the edges.

We remove the seventeen Phillips screws (PH # 00) that hold the intermediate casing, remove the card tray, and with the help of a fine tool we will unhook the sides of the casing making soft levers all around it.

We disconnect the battery to work with greater security.

We disconnect the bridge flex from the motherboard and the auxiliary, and with the help of a flat tool, we will take it off and remove it.

And finally, with the help of the stickers that surround the battery, we will take it off.
