VAIO VJS131 Disassembly

Last August, the VAIO laptop brand officially returned to the Chinese market with the VAIO VJS131 and VAIO VJS112 launched in Tokyo on January 24, 2018. These two thin and light laptops are powered by Intel’s 8th-generation Core processors and feature an optimized cooling system. In addition, the laptops feature unique VAIO TruePerformance technology, which helps increase the TDP of Intel’s 8th-generation Core processors from 15W to 20W, thereby greatly improving processor performance.

VAIO TruePerformance is a unique innovation in the lightweight laptop market. Today, we will start tearing down the VAIO VJS131 to explore its internal design.


There is a SIM card slot at the bottom.


Remove the dustproof cover, and then the SIM card slot can be seen. The Chinese version of the laptop may not have the relevant license, so it does not support 4G.


The screws on the back cover are exposed to the air. This design is rare to see in current laptops.


Take out all the screws on the back cover and disconnect all the snap joints at the verge of the surface with the keyboard, and then this palm rest can be removed. But be careful that there is a ribbon cable connection below it.


Before we continue the disassembly, we need to turn off the switch near the wireless card to avoid an emergency happening in the later disassembly.


After removing this palm rest, we found the keyboard, touchpad, and fingerprint scanner module installed there.


The ribbon cables of the three components are integrated into one place, making it easier for the user to assemble the device.



The fingerprint scanner module can be seen on the back of the circuit.


We need to take out the circuit of the touchpad’s this part.


This is the VAIO VJS131’s internal structure.


The laptop sports a battery with a capacity of only 35Whr, resulting from space wasting. The laptop’s battery is smaller compared with other lightweight laptops. The battery is made by a Chinese manufacturer.


The laptop has a cable manager for the Wi-Fi and LCD cables, which makes its internal design tidy.


Disconnect all the ribbon cables and remove the hinge to remove the screen.


Putting the laptop’s antenna on the top of the screen brings the best effect. This is the result that VAIO gets from the professional testing environment and test instrument. That’s why the VAIO laptops’ antenna is basically placed there.


It is the battery, screen, and surface.


The loudspeaker has proper volume.


The laptop comes with a Samsung SM961 SSD.


The Wi-Fi and Bluetooth two-in-one network card is from Qualcomm, and its module number is NAF344A.

Two USB 3.0 ports and the earphone port on the left are connected by a thick ribbon cable.


The sound chip is integrated into this small circuit board.

The front of the heat dissipation fan


Remove the shield cover from the motherboard, and then the clear heat dissipation module can be seen.


Heat dissipation module


Although the VJS131’s heat dissipation module only consists of a copper pipe, its copper pipe has a large diameter. Compared with the copper pipe that traditional lightweight laptops use, the VAIO VJS131’s copper pipe is much firmer. But it would be better if the copper pipe was shorter.


The back of the heat dissipation module


The vent is thick, which contributes to the improvement of the heat dissipation efficiency.


Take out the heat dissipation module and remove all the screws that secure the motherboard, and then the whole motherboard can be removed.


We can see the special mark on the motherboard, which is covered by a heat-dissipation copper pipe. There is no electronic component. This design effectively guarantees the stability of the motherboard’s work.


The part on the right is directly connected to the motherboard without other ribbon cable connections, allowing it to work stably for a long time.


The power button over the VGA port is not separated from the motherboard.


The back of the motherboard


The back cover uses nylon and fiberglass, which improves its size stability and gives it better heat resistance and higher impact strength. Besides, the back cover adds fire retardant, which makes it less possible to burn under high-temperature conditions.

 


Summary
After the disassembly of the VAIO VJS131, we found that there was nothing special in its internal design. But, the laptop uses high-quality material and has good workmanship in some parts. As a matter of fact, the VAIO TruePerformance technology has opened the Intel eight-generation Core i5 processor’s performance and enabled it to exceed the Core i7 processor’s performance. However, the laptop has poor space utilization of its internal structure.
