Some month ago I bought a laptop (not new). It got very hot so I opened up to see if there was some dust. Deep inside I found what I think is called a heatspreader (a thing of metall). I think it's supposed to be located on top of the CPU. What am I supposed to do? How do I get it back where it should be? I don't think it will stick only by putting it on top.
The component I thought was the CPU instead was something else. Maybe the southbridge or northbridge. So it's not that serious but I will try to put it back.
The cpu looks fine but I wonder one thing. The thing that is located over the cpu, graphic proceessor and some other thing that looks similar. It has a thick soft blue layer for the two other component but not for the processor. The processor has only a metal area to be touched by. Shouldn't the processor also have one of these blue things? There is a third blue thing on another place, quite near the processor that touches two small black boxes. I wonder if this blue thing instead should be over the processor? It could explain why it gets so warm.
I glued the heatsink where it belongs. After some searching I found that there was nothing wrong with how the CPU was connected but I putted some thermal compound (AS5) on it hoping it gets at least a little cooler. I haven't used it much since I did this so I'm not sure if the thermal compound did help but at least the computer seems to work as good as before I took it apart.
