When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

The connection between the battery and motherboard is a group of four wires in black housing that can be found near the top middle of the device. Using a plastic spudger or a flat, slim tool, lift the black connector housing upwards to disconnect it.
