Insert the iFixit opening tool in between the back panel and the rest of the laptop.

With the iFixit opening tool, lift the panel from the laptop body. Work your way around the device creating separation with the tool.

Once there is enough separation between the back panel and the device, gently pull off the back panel with your hands and completely remove it.

Make sure to use a plastic tool, not a metal one, so that you don't scratch the panel.
