Hello, this is my firt time opened any/my mbp, am not expert, just curious and have some questions about the logic board and thermal paste. The model I was checking the tutorial from ifixit and cant find information about those components on circle symbols. Heat sink tutorial say only about the green symbol, i think it's the processor ? And how about the others, they have a protect case, which i got no lucky to remove them - got one striped screw -, so i dont know if they came with thermal paste and if need to replace too. Questions What is those components with circle symbols, they need thermal paste? There is any manual to know what is each component on this logic board A1278? The protect cape from circle symbols have the same screw as keyboard ? For replace. For this kind of striped screw - really small - what is the recommend way to removed it? Thanks all o/ Just for who will open someday your mbp and is checking this, please, dont buy poor tools and have sure to the model of the screw you need to remove, before buying your replace components, make sure to have a nice tool set.
