Note* - Our previous top covers (a.k.a LCD Assembly) came preinstalled with everything such as a new camera, left/right metal hinges, wifi wires, LCD cable, etc. This time around the top covers for the 3100 non-touch only include the wifi wires. So, therefore, if you find a 3100 non-touch Chromebook with damage to the top cover, you will need to transfer the old top cover parts to the new top cover. This guide will show you the steps I like to take, but you can always go about the steps the way you see fit.
