Gently pull the heatsink up.
Take care not to lose the four cylindrical plastic spacers supporting the heatsink.
When replacing the heatsink, remember to place the spacers over the screw holes before screwing down the heatsink. It may be helpful to use tweezers to align the spacers if placing the heatsink on top shifted them.
When replacing the heatsink into the laptop, you will need to apply new thermal paste. We have a thermal paste guide that makes replacing the thermal compound easy.
If you need to remove the heatsink frequently, it is possible to replace the thermal paste with a 0.5mm thermal pad instead.
