If the I/O board for your Acer Chromebook (model C731-C8VE) is damaged, defective or generally needs a replacement, this guide is here to help you.

In order to remove the I/O board you must first remove the ribbon cable and the screw that is connected to the I/O board. After this is completed you should be able to gently slide the I/O board out and replace it.

You will of course need to ensure that your laptop is completely powered off and not connected to a source of power to avoid risk of electrocution or other injury.
