Just recently it had started to freeze or just display a black screen after being used of a while. I could hear the fan running but it seemed to get very hot. So I dismantled it and inspected the fan. The air outlets the fan through a sort of mesh that is about 10mm in depth. On this mesh I found about 5mm of dust blocking it. Cleaned it off, reassembled the laptop and hey presto a new lease of life.
Wonder how many laptops get binned because the fan needs cleaning?
