Question Lenovo 300e Chromebook - Mouse is gone

[BWhitney]

I have several Lenovo 300e Chromebooks with issues. Currently, the mouse is not showing on several.

I have:

1. Restarted
2. Powerwashed
3. Hooked an external mouse and it works fine.
4. Looked in the Chromesettings, but Mouse/touchpad does not appear.

Please help
