Don't fluff it

After fitting more memory and an SSD in Isobel's laptop we were disappointed to see that it was turning itself off after a while. This was an overheating issue caused by the dreaded fluff in the fan.
Big fingers, poor light and the wrong glasses meant getting at the fluff wasn't as stress-free as it could have been. But I got at it in the end. I had the usual one screw left over. I think they breed when out of captivity.
