Use an iFixit opening tool or nylon spudger to separate the case from the device.

Place the tip of the opening tool in the seam between the front and back case and slide it around the perimeter of the device to release the clips holding it together.

Use opening picks in the space to prevent the clips from reattaching.

Remove the back casing from your Chromebook.

Reminder: please use something plastic or silicone-based to pry the case off of the laptop. Using metal could damage the insides of something as delicate as your laptop.
