Written in the front: a few days ago to help sister clean up the laptop and print "old books of records - HP HP Pavilion g4", many friends reminded me that I should buy a new sister directly However, the thing of a thousand oceans is sent for delivery? The old computer can also use the ash to clean it. Later, after seeing the activities of the Xiaoxin Air 12 laptops on the public beta page, they took care to write a public test plan to see if they could send one to the sister. . . Originally prepared to be a denominator, because there are only 3 units, and the Aunt has gathered a lot of professional computer talent here. The probability of success of my ordinary digital fan is too low. Later, in the torrential rain on July 20th, I received a surprise message from the aunt and I was happy to jump. This is where De Se is finished. Here we talk about the text of the operation. Explain, I am just an ordinary computer digital enthusiasts, computer evaluation is not as good as those big gods, not satisfactory place, please also a lot of excuse me. According to the public measurement plan, the following contents are divided into: out of the box and appearance, notebook introduction, performance testing, use experience, simple dismantling, public measurement summary six parts, please choose the entrance. One, out of the box and appearance Out of the box there is nothing to look good, the aunt's "threshold value" seal is still domineering, the last move it Here we take a look at the details of the small new Air 12, the overall workmanship is very good, is definitely the finest entry notebook. A-side and D-side are all made of alloy material, so the combination of notebooks is very texture in your hand. A surface only has a lenovo logo, very simple The D-side is also simple because it uses a built-in battery and a fanless design. The palmrest is surrounded by a curved design that is even thinner in the hand. B surface shape design can not be said to be a failure, this frame is too touching. There are only two reasons why I can think of such a design: 1, technical considerations, in the premise of a 12-inch screen, in order to arrange a larger number of keyboards and increase the body space to place parts, had to increase the border; 2 Marketing considerations. Air 13 is also released. The latter's frame is a bit more beautiful. In order to differentiate with Air 13 in designing a B-side that is not very good-looking. . . The frame and the hinge below are made of plastic and should be for wireless signal transmission. There is a ring of black hard plastic between the frame and the shell to avoid direct contact between the B surface and the C surface. The right side of the camera is an indicator light that turns on when the camera is turned on, always reminding the user that the camera is on. . . Partially forced lower shaft In addition to the power button, keyboard keys, and touchpad, the rest of the C surface is also metal, and it is also a simple design. In order to compress the overall thickness, the keystrokes of the keyboard keys are short and the feel is a bit harsh. If you type for a long time, you will feel uncomfortable and you should not even think about playing games. Touchpad size, feel OK, support win10 most gestures, do not understand win10 touchpad gestures can click this link to ask the mother The maximum angle at which the screen can be opened The left side of the fuselage has a restart jack and a USB2.0 interface Right side of the fuselage from left to right is a key recovery jack, headphone microphone combo jack, USB3.0 interface, Type-c interface, power interface. The fuselage does not have any video output port and network cable interface, users with the need can buy the relevant Type-c adapter. Two USB ports may not be sufficient in some cases, so use Bluetooth as much as possible to choose a Bluetooth, you can save a USB interface Small new Air 12 main thin, in the end how thin it? Take a dime coin for reference Finally look at the power adapter, fairly compact Second, the introduction of small new Air 12 Xiaoxin Air 12 is Lenovo’s latest lightweight, stylish, long battery life, and cloud storage. It is suitable for handling lightly used portable laptops such as documents, audio and video entertainment, and browsing webpages. The performance of the netbook is stronger. It is suitable for people who have high portability, high facial value, and insensitivity to hardware performance, such as frequent business people. Lenovo invited Luhan to do endorsements and it must have also targeted the target market for young people (sisters) who do not have high hardware performance requirements, such as freshman freshmen. This is the main force for buying laptops in the summer. Since the main game is thin and there is no cooling fan, the hardware performance must be compromised. Let's take a look at the official data. The most critical CPU details are as follows: Use CPU-Z to see more detailed data The CPU performance section does not have any highlights, and is consistent with the positioning, does not support 4 generations of memory is a pity. The graphics card is not bad, as long as you don't play 3D games, you can meet most of your daily applications. The 4.5W TDP is the latest black technology, which is the basis for notebook manufacturers to make fanless products. There is not much to say about other hardware. Solid-state drives are standard on portable products. The 16:10 IPS display is a bright spot. It is more comfortable to use than the normal 16:9 screen. . . Third, performance testing Small new Air 12 positioning entertainment office, performance is not a selling point, this part is only a simple software running points and game testing. Non-professionals engaged in these for the first time. The test results are for reference only. (I believe that few people who really want to buy this notebook can understand the running points.) Let's take a look at SSD performance. The SSD of this machine comes from Lite-On. Based on the SATA interface, the performance is generally acceptable. Master Lu has always been disgusted by professionals, but the most common people still use it, more or less a little reference value I don’t know much about the scores of the following two professional test softwares. Professionals should let go of the bricks in their hands. Let’s have something to say. PCMARK 8 (Test version downloaded on Steam. Test scores can only be displayed on web pages) CINEBENCH R15 Although the small new Air 12 is not suitable for playing games, I still installed two games that are not so high in hardware requirements. After all, the gaming experience is more intuitive than the running points. The test results are even better than expected (I haven't played any of the two games. The League of Legends uses a novice teaching map, and the FPS may be lower in the network). League of Legends: Smooth running at 1920,1200 resolution with medium-high quality (game default), FPS between 40-60 Pass FireWire: The highest picture quality of 1080P can run smoothly, FPS has a maximum of 85, a minimum of 50, and most of the time is between 60-70. Fourth, use experience After using these days, the overall performance of the Xiaoxin Air 12 did not disappoint me: it was very thin and light, and it wouldn't cause much burden to carry with you; the battery life was good, and you could watch 5 hours of continuous 720P online video (80% brightness ) Although it did not reach the same level as an Apple laptop, it was sufficient for most occasions; there was no fan design and no mechanical noise; higher facial values ​​were also pleasing to the eye. . . Of course, the disadvantages are: The screen shaft damping is slightly larger, one hand to open the screen is slightly more difficult; mirror screen is easy to reflect; the keyboard feels not very good, not suitable for long input text; interface is less, use adapter will increase The extra cost will affect the portability; the position of the charging indicator light is not very good, and the charging status cannot be seen after closing the screen. The speakers of the small new Air 12 need to be mentioned separately. The sense of hearing is higher than expected. The medium and high frequency is clear and bright, and the volume is enough for everyday use. However, subject to the limitations of the ultra-thin body, the low frequency is obviously insufficient, and overall it is still good. Here are a few details that we are more concerned about Screen display effect: The display effect of the small new Air 12 display is good, the following is the actual performance, the first is the comparison with my desktop monitor (21.5 inches, 19201080, IPS) (beauty pictures found on the hummingbird, feel the display color contrast Portrait skin is the most obvious). The first one does not see much difference, but in fact the screen of the new Air 12 should be warmer. When the brightness is adjusted to the maximum brightness, the screen of the small new Air 12 is brighter than the desktop monitor, so the difference is not obvious. I calibrated the white balance with a white background cloth when I took the product detail picture above, and slightly yellowed the white background when I looked at those pictures on the Little New Air 12 It is obvious that the brightness of the small new Air 12 screen is adjusted to be the same as the desktop monitor. The most difficult thing to do when shooting a computer screen is Moorish. The top two images are almost invisible after the thumbnail, and Moleprint is particularly noticeable when you individually shoot the small new Air 12 screen. I have almost no post-experience experience, and I had no choice but to find a way to solve the problem in advance - the camera is at a 45-degree angle with the screen when taking a picture. Looking at the actual display effect, such a color performance should be in the upper middle level in all notebooks, and few in the same price notebook can surpass it. The small new Air 12 screen size is 12.2 inches, 1920x1200 resolution, in the monitor is definitely a high score screen. The advantage of the high score screen is that the display is fine, and more details can be displayed when watching a picture video. But in many cases, the high score screen will cause inconvenience to the user, the most prominent is the small text display, when the display ratio is 100%, it is simply to look at the blinking rhythm, so the machine factory default is 125% of the display ratio. WIN10's current support for high score screen is still not very good, 125% of the display ratio under a lot of interface display is not perfect, and some are still 100% watching effort, and some although it is enlarged but it looks vague. Browsing the webpage is also the same problem. 100% of the text is too small. If you zoom in, the image on the webpage will also be zoomed in, but it will become blurred. Personally feel that in the environment does not support the high score screen, this size screen with a resolution of 1440x900 would be better. Thermal performance: For a fanless notebook, heat dissipation is a concern. Thanks to the ultra-low power design of the Core M3-6Y30, the cooling of the new Air 12 is not bad, and it can be used casually without fear of overheating. The fanless design avoids the trouble of entering the ash, as long as the hardware is no problem can be maintenance-free for life. Body heat data, please see the following table, C surface, D surface temperature are measured with the highest temperature gun temperature parts, CPU core temperature is seen from Master Lu. Some time ago many aunt fans have bought this kind of temperature gun, a variety of installed machines, notebooks drying single, seemingly ran 1070, 1080 public test to go. The red box on the figure above shows the main heating parts. The temperature of the bottom frame of the B side is basically not affected by the load. It has been about 40 degrees. It should be caused by the display screen driving circuit heating. The temperature near the top right corner of the keyboard on the C side is higher, but no heat is felt in other places. The temperature of the black tape sticking to the D surface is the highest. According to the instructions of the temperature gun, the direct measurement of the metal surface has a large error, and it is best to stick it with a black tape. No heat is felt in other parts. The standby temperature in the form refers to the temperature at which no software is turned on after the power is turned on; the light use refers to the hanging of QQ, and the writing of this test on the Aunt Zhang website, driving a web page that is playing video, a spreadsheet; full load It is the temperature stress test of Master Lu; the League of Legends is the temperature of a medium-high quality game with a resolution of 1920,1200. From this, it seems that the Xiaoxin Air 12 has little heat when it is on standby or when it is used lightly. Even if it is put on the leg, it will not cause too much discomfort. Full use such as playing games when the heat is a little larger, the temperature of the hot parts of the hand touch is slightly higher, but far from the hot point. My residence has no air-conditioning, and the room temperature is close to 30 degrees. It would be even better if the air-conditioning house or the winter heat sink performs better. Lenovo cloud disk is also a key selling point for manufacturers, and the actual experience is not bad. The cloud disk is displayed as a disk in the system After opening, there are 4 folders for music, pictures, documents, and videos by default. Users can also add folders. Adding files to the cloud disk is the same as the local folder. Copy and paste it directly. After the file is put in, there is a sign indicating that it is synchronizing with the cloud, and the check mark is synchronized. Synchronization speed is fast, and unexpectedly fast. The bandwidth of my residence is 50M. This speed has exceeded the theoretical value. I do not know what accelerating technology Lenovo uses. Look at the cloud interface It should be noted that the cloud disk file will occupy the local hard disk space, and how many files in the cloud disk will occupy the local hard disk storage. Fifth, simple dismantling On July 27, Xiaomi released a laptop. When she was shocked, she took a look at the relevant information online and inadvertently saw the detailed dismantling of the Xiaoxin Air 12 in Zhongguancun. The professional work is indeed beautiful, I will not make a fuss, open the back cover simply show it The small new Air 12D shell does not have any buckles. Unscrew the 11 screws you see and you can easily remove it. This angle can be seen that the edge of the D shell is bent inwards, which is both beautiful and can increase the strength Take away the D-shell and look at the internal structure. It looks very simple, all kinds of originals are neatly arranged, and there are very few flying lines. It is a large-scale plant design, with internal and external repairs. The battery takes up most of the space, with three-quarters of the visual inspection. The main board is a small box, placed in the upper left corner, so the entire body's heat is also concentrated in that area D shell inside, you can see the speaker openings do dust treatment, four foot pads are hot melt stuck in the shell, that layer of black plastic should increase the shell heat absorption efficiency Simply look at other details From this we can see that the motherboard is reserved for 4G data interface, but the wifi version is not installed The following free space should be reserved for 4G network cards Sixth, all test summary Lenovo's new Air 12 is a well-crafted, lightweight and portable laptop with a beautiful appearance. Its 2999 pricing in the same configuration product is not high, coupled with excellent display, pre-installed genuine office software, very cost-effective. Comparing with the just-released millet Air 12.5" notebook computer, the conscientious enterprise of Meidi who feels firm also has a conscience in the motherland. So what's worth buying for this laptop? It depends on your budget and needs. The following people can use the Lenovo Xiaoxin Air 12 as an alternative when buying a laptop: 1, people who do not have high hardware performance requirements, such as students, hands of all ages. Usually chatting QQ, checking information, writing papers, visiting Taobao, watching videos, watching news, watching stocks are enough, and the price of 2999 will not have much financial burden; 2. People who carry laptops with them will not be burdened with the thin and light New Air 12 and can even be put into larger briefcases. Sufficient battery life can be guaranteed to be displayed at any time for customers, write contracts, send e-mails; 3, frequent travel or go out to play the crowd, the small new Air 12 can be used to relieve boredom in the free time, will not take up much space in the suitcase. Its excellent display screen is the most suitable for viewing photos on the road. It is also easy to modify the picture. 4, the pursuit of forcing people, the value of the new small Air 12 and workmanship to meet you! The key is not expensive! Thanks to Zhang Da Ma!
