After remove the screws that secure the back cover, carefully release all the snaps along the edge of the screen to separate the screen from the housing. Before remove the screen you need to disconnect two cables first.
When you split the screen assembly, the internal structure of the Miix 520 is unobstructed.
The two cables on the back of the screen are the display cable and the touch cable, and their circuit board is located in the lower right corner of the screen.
The layout of the cooling modules is quite satisfactory, but there is a considerable spatial surplus around the battery. The volume of the loudspeaker is also not large, which is the most obvious problem of the internal structure of Miix 520.
In addition, the two copper tubes used only a fan to be responsible for the heat dissipation. And a copper tube is passed directly above the SSD, so that the temperature of the copper tube is bound to raise the temperature of the SSD.
Under the battery we can see the contact of the magnetic keyboard, which is connected to the main board through a cable. Only five contacts can complete the signal transmission of the keyboard and the touch board at the same time. It is still amazing.
Unscrew the five fixing screws around the cooling module to remove the cooling module.
The back of the heat sink, you can see the bottom of the copper tube is actually covered with black insulating paper, which can prevent the copper heat conduction to the SSD.
The Lenovo Miix 520 comes with a Samsung 256GB PM961 PCIe NVMe M.2 SSD.
On the right side of the machine, there are two cables connecting the button on the right and the fingerprint recognition module respectively. The design of separation from the main board is beneficial to the convenience of maintenance.
The bottom case is also made of magnesium aluminum alloy with high strength. In addition, the antenna is also placed on the top of the machine to maximize the intensity of the signal reception and transmission intensity.
From the disassembly point of view, Miix 520 interior design is good, the maintenance is not difficult, and its internal space utilization also needs to be improved.
