Place the plastic opening tool into the edges between the front of the Chromebook and the back of it with the upper scoop of the opening tool facing upward.

Push down on the plastic opening tool to unhinge the top portion of the Chromebook from its lower portion. Opening the Chromebook all the way where the display touches the ground helps in opening up the top edge.

Use your hand to gently lift the top portion of the Chromebook from the bottom portion of it to avoid damaging the ribbon cables.
