Microsoft’s Surface family is notorious for its resiliency, but in 2019, the prodigal son turned back.
After iFixit’s disassembly, I found that I want to take apart the motherboard that looks at the Surface Laptop 3. I just need to screw out the four fixing screws that are distributed under the four legs. Inserting the refrigerator requires only three simple steps: removing the foot pad, unscrewing the screw, and separating the magnetic C and D faces. Finally, you don’t have to cut the Alcantara material to change parts! 
To this end, iFixit rated the repairability of the Surface Laptop 3 by 5 points (out of 10 points). For comparison, let’s review the “Glorious” record of the Surface family: the Surface Pro series received 1 point, 2 points, 1 respectively. Score, 1 point and 1 point, Surface Book scored 1 point, the same series of first and second generation Surface Laptop scored “Glory” scored 0 points.
In addition, the Surface Laptop 3 allows users to replace the M.2 2230 SSD by itself when all the components of the Macbook and the previous Surface Laptop are soldered to the motherboard. Conscience. Wait, what is M.2 2230? 
Microsoft said it is a smaller M.2 SSD than most conventional M.2 SSDs. For now, you can’t buy it anywhere, which means you can change it. But there is no place to buy it.
In fact, Panos Panay, the head of Microsoft Surface, talked about the high detachability of this machine when it released Surface Laptop 3. We don’t know if this is Microsoft’s technology upgrade, or if it changes the product design idea, anyway, if Can be further improved, I hope that Microsoft will allow users to replace the memory module by themselves.
