With the screws removed, we can now go about prying the bottom case apart from the top assembly

At the non hinge side of the laptop, carefully insert a prying tool in-between the two pieces and lift up

Continue to pry up the clips on this side until the entire front is unclipped

Then move to a side, I normally use the i/o side, but either will do. Continue slowly prying up the upper piece while trying not to damage the ports

When the bottom starts to lift away, move to the other side of the laptop. Again, pry the bottom case up until it becomes loose. Take extra care around the usb c port, as it is quite delicate.

Once this is complete, you should be able to lift the back case off
