When Choosing Commercial PC, enterprise customers usually formulate different inspection standards and purchasing strategies, hoping to choose professional and reliable productivity tools to maintain or promote the healthy development of enterprises. Among them, laptop protection is a very demanding feature. ThinkPad has always been stable and durable as its main selling point. The newly launched ThinkPad L470 business notebook brings this protective feature to the extreme. It is a customizable commercial PC solution tailored for large customers of enterprises. What kind of protection capability can this ThinkPad L470 achieve? This time, we sent it to Huabi Laboratory in Suzhou, and carried out the limit test of military standard. Can it pass the strict military protection performance? Let's take a look at the test results.
Notebook properties
ThinkPad L470 is inherited from the classic product appearance of ThinkPad Classic family. The professional and rigorous black business image has a very high degree of recognition.
Skin-like tactile matte paint is used on the surface, which can effectively prevent fingerprints and scratches while ensuring smooth texture. The metal fuselage ensures the strength of the whole machine, so that it suffers from impact and other external forces.
ThinkPad's classic little red dot design and superb keyboard feel are its charm. On this basis, ThinkPad L470 also adds the function of dust and splash prevention, which makes it more comfortable to use.
In the internal structure design, ThinkPad L470 also inherits the professional and reliable quality of ThinkPad series, adding APS hard disk protection, Eagle wing fan, diversion hole and other classical design elements. According to official accounts, ThinkPad L470 Business also passed 12 rigorous U.S. Military Standard Tests to maximize the protection of property and data security in daily use.
This time, we sent it to Huabi Laboratory in Suzhou and put ThinkPad L470 in the experimental cabin for GB/T 9813.2-2016 standard test to verify whether its extreme performance is really so strong.
Notebook Name: ThinkPad L470

Test conditions
For business notebooks, customers often face a variety of environments, especially for large business customers, because the people dealing with are scattered around the world, different geographical environments and bumps on the road are unavoidable, sometimes even in some extreme environments to use notebooks. This project is divided into three categories, all of which are standard control tests for different use environments and conditions. The test method refers to "GB/T 9813.2-2016 Computer General Specification Part II Portable Microcomputer", and notebooks that can run normally under the following icon standards are qualified products.
The following are the detailed test conditions and testing environment.
Low temperature test
The low-temperature test includes two projects, one is the low-temperature work test for the use of conditions, and the other is the low-temperature transport test for transport conditions, in order to test the adaptability of notebooks to low-temperature environment.
Hot test
The high temperature test also includes two projects, one is the high temperature work test for the use condition, and the other is the high temperature transport test for the transportation condition, in order to detect the actual performance of notebooks in the high temperature environment.
Resonance test
Resonance test is aimed at the notebook's adaptability to environmental sound and turbulent environment - as we all know, resonance will cause serious damage to notebooks, and qualified products can obviously be better used.
In this vibration test, the resonance frequency and the endurance of the notebook are tested. The endurance test is divided into two test schemes: fixed frequency test and sweep frequency test. The following are the test methods and standards of the resonance test.
Interpretation of test results and data
Low temperature environmental testing
Low temperature operation test
Cryogenic work may not be common to some people, but it's a daily necessity for others. Whether it's a person who goes to the polar regions or a business person who often travels to and from the cold regions, it's very important for them to be able to work normally in a cryogenic environment. This ThinkPad L470 is available in the It has also performed its duties perfectly in the low temperature work test.
ThinkPad L470 completed the test well in low temperature environment. From the test report, it can be seen that after two hours of low temperature working process, ThinkPad L470 can still operate and work normally, which is very meaningful for business people who often travel in cold areas - can work in harsh environment. Regular operation not only ensures the smooth progress of work, but also ensures data security in computers.
Low temperature transport test
However, people may also have doubts that the laptop in the boot state is itself a heater. If I shut down and carry it out, will I encounter the situation that it "never returns"?
It's also no need to worry about it. Our ThinkPad L470 performed equally well in the freezing test of minus 20 degrees. After 16 hours of ultra-low temperature test, the ThinkPad L470 can still run for 2 hours without any malfunction (of course, it won't work in two hours), which is enough. It shows that the product design of ThinkPad L470 fully takes into account the adaptation to harsh environment and has made good results.
Summary
Although low temperature environment is not very common in our daily use, but ThinkPad L470 can adapt to this rigorous environmental testing at least shows that its low temperature tolerance is still worth affirming. It can be imagined that in less severe cold environment, it will not have any unusual performance, it can be reassuring to everyone. It's used.
High temperature environment test
High temperature operation test
Comparing with the less common low-temperature working environment, high-temperature work is often our daily life. The comfortable environment in the office is not always accompanying us. The hot backpack environment and strong sunshine may cause electronic products to malfunction (yes, I'm talking about a bad summer). ) what is the performance of ThinkPad L470 in high temperature environment?
After working for two hours in a high temperature of 35 degrees Celsius, ThinkPad L470 also operated normally without any abnormalities.
High temperature transport test
The 55-degree high-temperature transport test is much more rigorous, and after 16 hours of closed "baking" test, ThinkPad L470 returned as if it had been in hell safely.
The high temperature of 55 degrees in real life basically means that the notebook is tightly wrapped and thrown into a freight truck at will. Generally speaking, if it's your own notebook, the owner will be distressed, but ThinkPad L470 has withstood such a "baking test" and has not been running for two hours. The adaptability of the environment to environmental problems is obvious.
Heat dissipation
In our previous tests, the test prototype has also achieved good heat dissipation performance after running for 1 hour, 46 minutes and 26 seconds under full CPU load. It can be seen that the ThinkPad L470 is more flexible in terms of temperature tolerance.
Summary: ThinkPad L470 not only withstands the low temperature baptism of minus 20 degrees Celsius, but also withstands the high temperature shock of up to 55 degrees Celsius. It can be said that it basically covers the temperature environment that everyone may encounter. Such tolerance performance is very affirmative. As a business notebook, ThinkPad L470 for The adaptability of the whole environment guarantees the smooth progress of the work to the greatest extent. It is a rare and valuable quality.
Resonance test
The final test project is resonance testing. In our daily life, we will not only face complex sound environment, but also complex bumpy journeys - and their common danger is vibration. Vibration at a specific frequency may cause resonance of notebook components, thus destroying the internal physical structure of the notebook. Therefore, resonance testing is also necessary for this commercial notebook.
定頻測試過程會持續30分鐘，而掃頻則會各進行5次
The purpose of vibration test is to simulate a series of vibration phenomena and test whether the product can withstand the test of vibration environment during transportation or use in its life cycle.
