Quality - General Tests

General quality control testing for all models*

All VAIO devices are strictly quality-tested so our users can have a smooth and safe laptop experience anytime anywhere. Through simulations of every possible scenario when using the device, dozens of stringent inspections are carried out to ensure the quality of our products.

VAIO abrasive test

Pursuit of a durable laptop
Everyday use causes normal wear and tear of the rubber feet and the bottom surface of a laptop. During the test, a 3kg weight is placed onto the VAIO laptop and rubbed against the laptop surface. No excessive abrasion is spotted.

VAIO drop test

Withstands the impact of falling – the quest for durability
Laptops are subject to huge impacts when dropped from a work surface. Proper protection to the motherboard and the screen can minimize the risk of losing important data. Testing shows that VAIO laptops can still boot normally after extreme impact.

VAIO dust resistance test

All ports and vents are dust-proof
Dust is the main cause of the drop in laptop performance. Poor ventilation due to dust accumulating around ports and openings may cause the device to overheat. To ensure that dust will not affect the operation of VAIO laptops, we use our self-developed device to test our product where it is placed in a dust-filled environment. The simulation shows that VAIO laptop can operate normally under such circumstances. We have also made changes to the design of the parts of which dust easily accumulates, maximizing the device’s dust-proof ability.

Ensures radiation level is safe
All electronic devices emit electromagnetic radiation that may have a certain impact on the human body and other electronic devices. While each country has its own specific radiation emission limit, we design and manufacture VAIO laptops in accordance with the regulations of the countries of sale. We measure our laptops’ radiation level of in a specially designed room where special materials are used to absorb the radiation emitted. We also test the strength of the signal received by the built-in wireless card antenna inside the VAIO laptop. The laptop is affixed on a test bench that rotates in all directions to assess the signal reception while fully considering the influence of the surrounding environment.

VAIO anti-static test

Protected from static electricity.
Static electricity can cause serious harm to laptops. In the static electricity testing, an electrostatic generator is used to emit static electricity to an operating VAIO laptop in order to determine whether it will cause any damages or malfunctions. Static electricity is ubiquitous, especially in winter and drier seasons when people often experience static electricity shocks. Therefore, we have improved the laptop design to tackle such a problem. During the electrostatic discharge test, we simulate different scenarios where the user uses a VAIO laptop while statically charged, including touching the screen, the laptop surface, the keyboard and the gap between the buttons. We also inspect the laptop components that are sensitive to static electricity, such as the chips on the mainboard and the USB ports, for further improvement, enhancing the stability of VAIO laptops.

VAIO screen pressure test

Durable screen after extreme compression
Mishandling of the screen may happen anywhere, anytime, and many people grab the screen directly when carrying the laptop. The screen is a vital part of the VAIO laptop and once it is damaged, the device may not work properly. As a result, two kinds of pressure test are carried out to help improve the design of the screen: one is to use a hydraulic press to apply force to directly onto the screen, while the other is to apply force at a point in different positions of the screen.

VAIO vibration test

Durable after severe vibrations
Laptops experience all kinds of vibrations and drops during transportation, especially for frequent commuters. In the vibration test, VAIO laptop is affixed on a test bench and undergoes severe vibration over a period of time. The testing simulates various vibration scenarios such as in a subway/car, when idling, and when packing. Dents and damages found on different components are analyzed for further design improvements, increasing the shock resistance of VAIO laptops.

VAIO impact test

Survives large impacts
Both shocks and drops will have huge impacts on laptops. In the impact test, we analyze the damages to the motherboard, hard disk and other components caused by direct impact. Potential issues are identified and reported to the development team for further analysis and improvement. Our goal is to ensure that all components are strong and durable.

VAIO hinge durability test

Durable hinge that withstands repeated opening and closing
Opening and closing the lid are evitable every time when using a laptop and demand high standards of the hinge between the screen and the body. We test the hinge’s durability by repeatedly open and close the lid for the number of times that equals years of the opening and closing action, so a strong and durable hinge can be selected. Additionally, wires connected to the screen are hidden inside the hinge. Therefore, the laptop is on during the test as to verify whether the wires will break due to repeated opening and closing.



※ Quality tests are carried out in specific environments based on VAIO’s regulations. The product’s quality tests do not guarantee that it is free from any damage or malfunction, nor do they guarantee the safety of the data in the SSD.
