Flip the laptop over and open the screen.
Gently pry the keyboard and trackpad panel away from the bottom housing using a plastic opening tool.
Once completely separated, do not immediately pull the panel completely away from the bottom housing. There are wires that are still connecting the panel to the rest of the internals of the Chromebook.

Has anyone gone through the experience of replacing JUST the keyboard? It looks like they are available as a separate component, e.g. https://www.ebay.com/itm/New-for-Lenovo-... but I haven’t found a tutorial on removing the keyboard from its bezel. Thanks!
