I was playing on my five year old ps3 40g and it gave out on me. Started to show the yellow light when I reset it. So I found to repair kit.
Started off bad because my smart cover had melted to the play station to it self. So I had to cut the edge of the cover to free it. But from there it went fast.
The step on ifixit are for a 60g ps3 and my 40g has less parts and different layout. So take good notes on the screws
