Introduction
If the motherboard for your Acer Chromebook (model C731-C8VE) is damaged, defective, or requires replacement for some other reason, this guide will help you to do so with ease.
Before removing the motherboard, you must remove cables that connect to peripheral components and the screws that hold the motherboard in place. Afterwards, removing the motherboard is as simple as lifting it out of place.
