Einleitung

This is a guide to replace a faulty motherboard in an Acer Chromebook CB3-431-C5EX laptop. You will need a Phillips #0 screwdriver, iFixit opening tool, Tweezers, and a Heat gun. Be cautious when removing the motherboard because of having to handle wires.

    • Working on your device while it is turned on may result in electric shock. Make sure to shut down and unplug your device before you begin.

    • Turn device over so the bottom panel is facing you.

    • Remove the eight 4mm Phillips #0 screws.

    • Remove the two 6mm Phillips #0 screws.

    There are two tabs on the battery opposite the connector side that need to be inserted into the retention slots or the battery won’t sit flat. Need to do this before reinserting the battery screws.

    Also, I found that #00 Phillips works best on the 4mm screws.
