    • Power down the Chromebook before starting the repair.

    • Opening the Chromebook voids the manufacturer warranty.

    • Flip the Chromebook so that the bottom is facing up.

    • Use a Phillips #1 screwdriver to remove the six 6.6 mm screws on the bottom.

    • Use a spudger to remove each of the 4 rubber feet.

    • Use a Phillips #1 screwdriver to remove the four additional screws under the rubber feet.

    There is also a screw under each of the 4 rubber feet that must be removed.

    Thank you for that little bit of important information. I almost torn apart the keyboard using too much force :)

    @Aaron Kurtz, I just updated the guide. I’ll see if I can add any pictures later.

    I feel like i’m doing something wrong. It’s hard to get the new keyboard pushed in. Im afraid i’m going to break it.

    I feel like I am doing something wrong. I got the keyboard off no problem. Put the replacement on and I feel like it’s going to break when I try to push it back in the frame.

    You should update the guide. As Aaron Kurtz told long time ago there are screews under the feet. It is said in the comments, but not in the guide. I’m afraid somebody may break the keyboard…

    • Flip the Chromebook back over and open the screen.

    • Wedge the plastic opening tool between the keyboard and the bottom of the Chromebook.

    • Run the plastic opening tool along the seam between the keyboard and the bottom of the Chromebook until the keyboard moves freely. Several tabs will pop out.

    • It is normal for the tabs to make a loud click when released. The corner tabs will be harder to release than the others and will make a louder click.

    • Once the keyboard is released, grab the two top corners closest to the screen and slowly lift the keyboard up.

    • Do not lift the keyboard quickly or you might break the two cables that connect the keyboard to the motherboard.

    • Disconnect the cables by lifting up the retaining flaps on the black ZIF connectors.

    • Slowly pull the cables up and out of the connectors.

    • Lift the keyboard up and off the back panel, exposing the motherboard and battery.

    Hmmm. So I found that once I had got the keyboard section off the motherboard/battery section that there was a metal plate which was holding the keyboard in place. I found a YouTube video, White Angel I think, and showed how you could get the plate off to be able to replace the keyboard.

    There are screws under the rubber pads on the bottom that need to be taken out as well. I fix these as a school where we literally have hundreds of these. There is no metal plate as described in the comment above. Rubber pads have letters and are not interchangeable with the other corners.

    Ed, he's talking about the metal plate fastened to the keyboard once you remove the palm rest assembly. You’re referring to removing the initial external bottom screws.

    White Angel shows us how to replace the keyboard in the assembly, which saves you about $20 in parts vs. buying another full palm rest assembly.

    The only issue is that she pops the plastic tabs largely holding the metal plate in place- and never repairs them. So the keyboard looks nonfastened and gerry-rigged.

    Might be worth spending the extra $20 for the full assembly in the long run.

    Cheers

    • Disconnect the speaker and battery cables from their sockets on the motherboard by using the edge of the plastic opening tool to separate the cable connectors from the sockets.

    • Pull the cables towards you and away from the sockets.

    • Wedge the plastic opening tool between the rubber foot and the bottom of the chromebook. Lift up the plastic opening tool to remove the foot. This exposes the back end of a screw holding down the motherboard.

    • Flip the laptop on its top so that the screen is facing up and the back panel is bent at a 90 degree angle. This will allow you to see both the gold nut and the screw.

    • Hold the gold nut steady with a pair of needle nose pliers.

    • While holding onto the gold nut on the motherboard, remove the 6.5 mm screw on the bottom of the chromebook by rotating the Phillips #1 screwdriver to the left.

    • You may need an extra pair of hands for this step.

The gold “nuts” as you describe them should not remain inside the machine. Those are the keyboard mounts and should have be removed when the keyboard was removed. They should have remained inside the keyboard itself.

Where is the ram stick???

The motherboards arrive with only Shopfloor diags on them. The SHIM build instructions don’t seem to work. Finding the process to complete the new installation after the hardware component seems to be impossible.
