Requirements:

A soft underground
– You could use a towel

A container to put the screws in
– Make sure you don’t lose the screws

Daughterboard power button with LED
Screwdriver
Spudger (or a similar plastic tool)
Thermal paste with a spatula
Metal cleaner
Wet wipes
Microfiber cleaning cloth

Put the laptop upside down on a soft underground.

This is needed to prevent scratches on the laptop’s screen lid. Then, remove all the screws with the screwdriver.

Take the spudger and put it between the bottom case and the hinge.

Gently apply pressure to the hinge. Do this on both sides. You can then carefully remove the bottom case entirely.

Disconnect the battery temporarily.

This is a security measure to avoid short circuits.

It is highly recommended to do this step.

Unplug the heatsink cables.

Remove the heatsink screws. The screws that are marked with the numbers 1 and 2 stay in place, while the other screws go out entirely.

Carefully lift the heatsink at both sides. This can be a bit stiff because of the sticky thermal paste.

Remove its four screws.

There is no glue under the battery, so you can just take it out after removing the screws.

Use the micro screw driver to press in the keyboard screw fit, while the laptop is on its side.

The keyboard will pop out on the top.

Use your fingers to further remove the keyboard from the chassis, while the laptop is in its normal orientation.

Remove the 2 clables that holds the keybord.

Disconnect the cable shown in the image.

Disconnect the cable at the top left (camera and microphone) and the two white cables that are blue at the end.

Disconnect the cable for the screen (top right) and disconnect the CMOS cable (bottom left).

Remove the two power button daughterboard screws and disconnect the FFC cable.

Remove the power button daughterboard itself and replace it with the new one.

Reconnect the FFC cable and use the two screws to make sure that the power button daughterboard stays in its place.

Install the new motherboard while making sure that all the cables are visible.

Now connect all cables to the motherboard. Remember that there is one more FFC cable on the other side.

Reconnect all the other cables that you have removed in step 8

Place it into the right position.

Mount the screws back in place by using the screwdriver.

Remove the termal paste with the spatula

wipe the rest of the termal paste off with a cleaning wipe

Use a cloth and spray metal cleaner on it to clean it thoroughly.

Put some thermal paste on the spatula.

Spread it out on the CPU (and NVIDIA GPU, if present) evenly.

Make sure that you no longer see the mirroring effect of the CPU (and NVIDIA GPU, if present).

Carefully place the heatsink back in its original position.

Make sure that you don’t move the heatsink after putting it back in place.

Install and tighten the heatsink screws and reconnect the heatsink cables.

Reconnect the cables shown in the image.

Reconnect the cable you removed earlier (top left).

Make sure that there is soft material on the palm rest part. This will prevent scratches.

Put the keyboard upside down on this soft material to easily attach the keyboard cables to the motherboard.

Put the keyboard in its correct position.

Make sure that you put the bottom side in its place first by shifting it to the bottom.

Press the keyboard on all sides, reconnect the battery cable and the CMOS cable

Install the bottom case by placing it back in the right position.

Gently press the part on all sides.

Make sure that the bottom case fits snugly on all sides.

Use the screwdriver to install the screws back in place.

This was the final step, you are ready to use your laptop again.

Well done!
