I often see many business people in various places and at various times dealing with various matters on laptops. The variety of laptop models is dazzling, and the various sizes are overwhelming. However, we have to consider not only its portability, but also its size, comfort, and decent performance. There don’t seem to be many choices for such a machine. The model to be introduced below seems to give us a new perspective.

The emergence of Lenovo Yangtian M40 gives us a brand new choice. Its 21mm body is comparable to ultrabooks, and its 1.6 The overall weight of kg has certain advantages in terms of portability. In terms of configuration, Lenovo Yangtian M40 uses Intel Core i3-4030U as the processor, and is also equipped with an AMD Radeon R5 M230 independent graphics card. You can also use games to relax appropriately after business work. In addition, It also has a configuration combination of 4GB DDR3L 1600MHz memory and 500GB mechanical hard drive.

Lenovo Yangtian M40 business laptop adopts the Journal ID design, which also reminds us of the previous BOOKID design style of Lenovo U300s. They also allow the notebook to be opened and closed like flipping through a book. And then you can explore its inner depths. The top cover of Lenovo Yangtian M40 is made of metal sandblasting process, which is quite classy and effectively solves the problem of fingerprints. The brown and gray color scheme is low-key and calm. Although it looks "tacky", it is indeed very consistent with the office style of business people.

The overall thickness of Lenovo Yangtian M40 is only 21mm, which is completely comparable to ultrabooks in this regard. At the same time, the overall weight of 1.6kg is also quite good for a 14-inch notebook. If the user has the conditions to replace the mechanical hard drive with an SSD solid state drive, the Lenovo Yangtian M40 can instantly become a qualified ultrabook product. ​

Simple interior

Lenovo Yangtian M40 uses a full-size chocolate high-touch keyboard with certain keycaps The concave curvature makes it easy to fit your fingers. The surface of the keycap has been frosted, so it feels more comfortable. The wrist rest is made of metal and has a good overall feel. There is also a Mic pickup hole on the edge of the wrist rest. The integrated touch panel is embedded in it, the touch accuracy is good, and it can support multi-touch and various gesture operations.

Extreme test

We use it. Furmark copy software performs an extreme test on the Lenovo Yangtian M40. Furmark will fully operate the CPU and graphics card, the two major heating components of the machine. After 60 minutes of operation, the temperature will reach an extreme height. In order to allow everyone to more intuitively To see the heat dissipation of each machine during operation, we also used a FLUKE infrared thermal imager to observe the temperature rise at each location.

Heat dissipation test

Although Lenovo Yangtian M40 is a business notebook, we still have to test its heat dissipation. After passing the extreme copy test, we can see that Lenovo Yangtian M40 The maximum temperature in the keyboard area is about 45°C, concentrated in the middle of the keyboard area. This situation has basically fully released the performance of the graphics card and CPU, while most other temperature controls are still very good, especially the palm rest and The touch panel part is kept below 35°C.

Relatively speaking, the heat dissipation performance at the bottom of the Lenovo Yangtian M40 business laptop is better, except for the heat dissipation window part which reaches above 50°C. Most of the remaining temperatures are controlled below 35°C. Under extreme copying conditions, such temperature feedback results are considered very good. In addition, during daily use, it is difficult for users to let the whole machine reach such a high temperature.

Battery life test

In order to cater to the new Windows 8 operating system, we have also upgraded the battery life software test. The software used in the new version of MobileMark 2012 is the same as the previous version. A lot of upgrades have been made.Through the test of the new version of MobileMark, we can see that the battery life of Lenovo Yangtian M40 is 246 minutes, which is about 4 hours. The efficiency value of 96 is considered satisfactory.

Lenovo Smart Center

"Lenovo Smart Center" is a client software that integrates local and cloud platform applications and services. It aims to provide services and comprehensive solutions to the general needs of small and medium-sized enterprises, and to bring users a friendly and diverse desktop experience. "Lenovo Smart Center" is a desktop, one-stop integration of pre-installed software applications and online applications in Yangtian products. It not only has basic applications such as one-click recovery, Phone Companion, Lenovo VeriFace Pro, etc., but also includes online Business management systems such as office, accounting, and project management, as well as online training courses in IT skills, English, marketing, and professionalization.

This Lenovo Yangtian M40 is quite excellent overall and is another excellent choice for business people. Its appearance is quite satisfactory.
