Steps

Time Required

Introduction

The purpose of this guide is to demonstrate how to replace the daughterboard of the Acer Chromebook CB0311-1H-C1MX. The daughterboard is a smaller circuit board that acts as an extension of the motherboard. It has two separate sections: one is connected to the motherboard by a cable, and one is hidden under the left hinge.

If the device is experiencing issues with network connection, audio processing, or USB port connection, the daughterboard may need replacement.

Tools

Step 1

Using a JIS #1 screwdriver, remove eleven 6.6 mm screws from the back cover.

Step 2

Beginning at the hinges, use an iFixit Opening Tool to pry open the back case.
Continue using the iFixit Opening Tool around the entire edge of the case.

Step 3

Using a JIS #1 screwdriver, remove all four 4.8 mm screws holding the battery in place.

Step 4

Gently push on either side of the silver connector so that it no longer covers the battery cable.
Disconnect the battery cable by pulling it straight out.
This component is called the Flat Topped Connector.
