Which means your clip is not on good enough.
It can be a pain on some models. Make sure the clip is flush to the motherboard on all 4 sides. And tape it down securely. On some slims there is a transistor in the way and you have to shave some of the clip to make it fit. I have also used coins to make a permanent push on the clip when you put it back together.
