    • Use the point of your spudger to pry up the heatsink shield from its clips on the motherboard at these spots:

    • The bottom left corner, just below the white arrow

    • The bottom middle, just to the left of the QR code

    • The bottom right, just above the white arrow

    • The white arrows indicate preferred prying locations. However, prying between the shield and the motherboard at these spots risks damaging small components.

    • Use your Phillips screwdriver to remove the four 3 mm screws securing the heatsink.

    • During reassembly, tighten these screws in an X-pattern. For example, begin with the top right, then bottom left, top left, and finally bottom right to evenly compress the thermal paste.

    • Pry the heatsink from the thermal paste bonding it to the CPU.

    • Depending on the age of your laptop, this might require some force. If it feels stuck, gently rotate it back and forth.

    • Remove the heatsink.

    • During reassembly, clean the old thermal paste from the CPU and the heatsink (if you're reusing it) and apply new thermal paste before installing your heatsink.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
