To begin with, we must apply heat to the back cover in order to soften the adhesive that holds it, and with the help of one or more plastic spikes we will peel off all the edges of the case.

We extract the eleven Phillips screws (PH # 00), which hold the intermediate casing that covers the motherboard area, and with the help of a flat tool we will unhook it.

We disconnect the battery to work with greater safety.

We extract the four Phillips screws (PH # 00) that hold the card reader, we extract the tray with the extraction tool, and by disconnecting the flex of the reader from the motherboard we will be able to completely remove the reader for greater comfort to remove the battery.

To detach the battery we will follow the instructions of the adhesive, first we will detach zone A from the sticker, then we will do the same with zone B, and finally we will pull zone A upwards and it will come off little by little.

We can introduce a few drops of isopropyl alcohol along the edges of the sticker once it has been removed, in order to soften the adhesive that holds it.
