Asus Chromebook C300SA-DS02 Motherboard Replacement

Difficulty

Moderate

Steps

Time Required

50 - 55 minutes

Introduction

If your Asus Chromebook C300SA-DS02 motherboard breaks or becomes damaged and you need to replace it, follow this guide. You will need to remove the back cover and keyboard to access it and follow several other prerequisite guides before you begin.

Tools

Step 1

Power the laptop off and make sure the charger is unplugged before starting.
Remove the eight 8.0mm Phillips #0 screws on the bottom of the laptop.
Remove the three 6.0mm Phillips #0 screws.

I appear to have FIVE of the smaller screws. The four securing the near edge and the one in the center are smaller than the four securing the far edge and the left and right sides. Either your diagram is wrong, or someone screwed mine together incorrectly.

Mine is the same way — six long screws, five short ones. The screw paths seem to correspond accordingly.

Step 2

Open the laptop.
Using an iFixit opening tool, pry along the edges of the keyboard.
Lift the keyboard and slide it gently towards you.
Do not completely remove the keyboard. It is still connected to the back panel by a pair of ribbon cables.

Step 3

Disconnect the two ZIF connectors by prying up the locking bar with a spudger and removing the ribbon cable.

Step 4

Remove the keyboard from the laptop.

Step 5

Remove the six 5.6mm Phillips #0 screws around the battery.

Step 6

Using your thumb and index finger, pinch the multi-color cable and disconnect it from the motherboard.

A serious omission is that there is a metal clamp holding the battery connector in place that MUST be slid back in order for the connector to be lifted up and off.

Step 7

Lift the battery out of the laptop.

Step 8

Unplug the black and white cable from the motherboard.
These two wires connect to the antenna within the display assembly. The white cable is longer and connects to the bottom import.

Step 9

Peel back the tape covering the display cable.
Ease the cable towards the screen and out from the connector.

Step 10

Use a Phillips #0 driver to remove the six 5mm screws on the top right and left display hinges.

Step 11

Gently lift the display assembly up and away from the laptop.

Step 12

Use the spudger to pop the black and white coaxial WiFi cables up from the WiFi card.

Step 13

Remove the one 3.6mm Phillips #0 screw from the WiFi card.
Pull and lift the WiFi card away from the motherboard.

Step 14

Using your Phillips #0 screwdriver, unscrew three, 3.6mm screws from the silver heatsink.
Remove the heatsink from the motherboard.

Step 15

Remove the black tape from the motherboard covering the 4.2mm silver flat screw.
Using a Phillips #0 screwdriver, remove the 4.4mm screw on the right and the 4.2mm silver flat screw on the left from the motherboard.
This is a used device so the screws may be different than the original Chromebook.

Step 16

Using the black nylon spudger, unlock the black bar on the ZIF connector attached to the mid-right of the motherboard.
Remove the ribbon cable that attaches the motherboard to the daughterboard.
