▲ Top cover design of rhythm stripe technology
Lenovo Zhaoyang K27 screen top cover adopts black rhythmic stripe technology to avoid fingerprints, and the top cover and palm rest adopt cemented carbide. While ensuring exquisiteness and compactness, its fuselage is also stronger. The screen shaft adopts double buckle design, and the resistance of the shaft is moderate. When the screen is opened to any angle within the range of 180 degrees, it will not shake. The edge of the top cover is wrapped, which makes the screen of K27 extremely strong. No matter how hard you press the top cover of the notebook, the screen will not be affected.
▲ The maximum opening and closing of the screen can reach 180 degrees.
▲ Adopt 12.5 inch frosted screen design.
The rubber pad around the K27 screen in Zhaoyang and the folding treatment of the screen edge can ensure that the screen will not be scratched by the keyboard area to the maximum extent, and the latter can also effectively prevent the dust entering from the gap from directly adsorbing the screen when the notebook is closed. Careful friends may find that we also saw many classic ThinkPad designs on the fuselage of Zhaoyang K27. In addition to the folding design of the top cover edge, on the left side of the camera, the LED keyboard light is also retained, which makes the user more comfortable to operate at night.
▲ Classic splash-proof keyboard design
The indicators such as shortcut function keys of Zhaoyang K27 are all concentrated in the bar area above the keyboard, and the indicators of hard disk status, digital status, chassis status and hard disk status are concentrated in the middle part, and the most common system recovery function keys of Lenovo notebooks are provided, which avoids the trouble caused by software crash in any case. Function keys such as system rescue, mute and hard disk protection are designed above the keyboard.
▲ Standard fingerprint identification system
Zhaoyang K27 adopts high-touch keyboard design, which conforms to ThinkPad standard keyboard in terms of key cap shape, appropriate key distance and feel. In addition to the lack of little red dot inherent in Xiaohe, the K27 keyboard is first-class in use. In addition, the keyboard also has waterproof function. Through the design of the bottom diversion hole, users don't have to worry about the damage of the equipment caused by the beverage splashing on the keyboard, which improves the safety of the equipment and data. In addition, the fingerprint identification system on the right side of the palm rest, combined with random software, can log in through the fingerprint identification system, further improving the security of the platform.
▲ Support multi-touch
Lenovo Zhaoyang K27 has a large gap between the touchpad and palm rest, and the touch area is grainy, so you don't have to worry that your fingers will inadvertently move out of the effective operation area when operating.
▲ Port layout on both sides of the fuselage
Because the mold specification of Zhaoyang K27 is obviously smaller than the mainstream business book, it also increases the design difficulty of interface layout. Because the solution of external DVD recording drive is selected, its products provide universal interface expansion and its interface layout is reasonable. The main interfaces are designed on both sides of the fuselage, and the interfaces are loosely distributed, so it is not easy to conflict when connecting multiple peripherals at the same time.

▲ Comprehensive Office Performance Test: SYSmark 2007 Preview Edition
As a product for positioning portable business applications, the execution efficiency of Zhaoyang K27 in the daily business application environment is what users are most concerned about. We chose SYSmark 2007 Preview to consider the effect of this product in e-learning, video creation, work efficiency and 3D modeling application. Overall, the performance of Zhaoyang K27 in four common office applications is satisfactory, with a comprehensive score of over 200 points. Thanks to the good combination of processor and memory, the advantages of video creation and execution efficiency test are the most obvious.
▲ standard 14.88V/4 1Wh lithium battery.
At the beginning of the article, we have already introduced that one of the characteristics of Zhaoyang K27 notebook is to give consideration to safety and portability, and users can even choose the dual lithium battery scheme to obtain a longer service life than before. In the actual test, we chose the random standard six-cell battery of 14.88V/4 1Wh, and tested the endurance of the random battery through MobileMark 2007.
▲ Screenshot of ▲Mobilemark2007 test results.
In the test, we turn off the screen saver sleep and set the battery and system to the highest performance mode as the test basis. As can be seen from the above picture, this battery as standard in Zhaoyang K2 has been used for 269 minutes, which can basically meet the office needs of most people.
From the previous test experience, the notebook computer with integrated display will not have too high power consumption under high load environment. Considering the mold design of 12.5 inch, its internal heat dissipation space is more cramped than that of mainstream business books, so the performance of its products in heat dissipation effect deserves attention. In the test environment of 25 degrees Celsius, we chose Everest software to conduct a comprehensive baking machine test on the system. After 15 minutes' test, we use UNI-T UT7 1E intelligent digital multimeter to detect the high load power consumption of the product, and after 30 minutes, we use infrared thermometer to investigate the highest temperatures at many positions on the fuselage surface.
▲ Heat distribution on C surface of notebook fuselage
▲ Heat distribution at the bottom of notebook fuselage
▲ calorific value of fuselage outlet
From the test results, the overall power consumption of the product is not exaggerated under the processor matching of 32nm process, and the power consumption of the whole machine is only 49.4W under high load operation environment. Just because of the design of the fuselage mold and the narrow internal space, under the long-term and high-load working environment, a little heat accumulated in the middle area of the C-plane of Zhaoyang K27 notebook, and the highest temperature reached 38.4 degrees Celsius. In contrast, the heat accumulation of its bottom core components is more obvious, reaching 39.6 degrees Celsius near the air outlet of the processor. The highest temperature of the fuselage comes from the main air outlet of the processor, reaching about 50 degrees Celsius. If the surface temperature is ideal for a 12.5-inch product, because the radiator is designed on the left side of the fuselage, such heat generation has little effect on most right-handed users.
With the sudden emergence of business products for a new generation of office users, more and more manufacturers began to seek a balance between appearance, function and practical application effect, and a new generation of business notebook market gradually formed. However, product design and component performance are based on safety, portability and durability. The Zhaoyang K27 notebook we tested for you this time is a lightweight, portable, fully functional, safe and stable product. ?
