Speaking of black and silver laptop , a variety of models may appear in your mind, but what about white? I believe that all viewers will be stunned for at least a few seconds, and after a while, they can only tell the sporadic models. Yes, not only in the laptop field, but also in the entire consumer digital field, white is a very rare color scheme. Although manufacturers also know consumers' love for white, due to problems such as craftsmanship, cost, etc., few manufacturers are willing to make white products. Even if they are made, they are basically "special editions" and "limited editions", or they are not able to grab them, or they are much more expensive than ordinary editions.
But this one in my hand is definitely an exception. The whole body is white, both the middle frame and the screen bezel are white. With such a design, it is not a limited edition, but an ordinary mass-produced model. This appearance is really a glance, and I don’t know how many people have hit the nail on the head.
Without further ado, let’s take a closer look at this one, dynabook EX40L-J.
Let’s first check the configuration of my test machine:
CPU: Intel Core i5-1135G7
GPU: Intel Iris Xe core graphics card
Memory: 16GB DDR4 3200MHz
Solid state: 512GB SSD
1. Appearance is justice!
When friends or acquaintances around me want me to recommend a laptop to them, the products I recommend are laptops with relatively high appearance. Although hardware and performance are a very important indicator for buying a laptop, for daily office needs, based on the current hardware level, no matter how good the performance adjustment is, there is no obvious difference in actual use, and "good-looking" and "pleasant" are more intuitive and are a very important attribute.
When I first saw the dynabook EX40L-J, I was very surprised by its white design. To put it simply, as long as it can be white, it will be white. The screen frame, the middle frame of the body, the entire D-side, and even every keycap of the keyboard, the screen axis, the foot pad at the bottom, and even the area of the physical anti-peeping camera are white. The white is really too thorough.

This design is almost extinct. The white body has extremely high requirements for the process, such as color difference problems. In such a large body of laptops, it is very difficult to maintain the unity of "white" visually. The dynabook EX40L-J can do this, which is definitely strong enough.

The position in the middle of the A-side is the dynabook mirror LOGO on the carved surface. Usually, the notebooks with office attributes often will not have any decoration on the A-side, and most of them are a plane. However, this EX40L-J has a small protrusion near the axis of the A-side. The middle protrusion dissipates to both sides, adding a bit of three-dimensional feeling without being abrupt. And compared with the entire plane, this small protrusion has a much higher requirement for the process, and the cost of opening the mold will naturally increase.
screen surface is designed with a narrow bezel. According to the information given by the official, the borders on the left and right sides are 6.4mm, the screen-to-body ratio is 81%, a 14-inch IPS screen, a resolution of 1080P, and an anti-peep camera above the screen, supporting face recognition technology. The screen axis can rotate 180 degrees, and the screen display can be flipped using CRTL+ALT+up/down arrow keys. You can quickly display the screen content to colleagues during meetings and discussions, without having to squeeze together awkwardly.

Seeing the C side, the first thing that caught your eye was this pure white keyboard. The pure white keycap looked beautiful in an instant, but as soon as you touch it... the plastic feel was heavier. Fortunately, the key stroke was longer and the typing felt good. The power button is located in the upper right corner of the C plane, independent of the keyboard area, avoiding accidental touch. If the power button is also white, it would be even better. The area where the touchpad can be pressed is relatively large, the touch feels smoother, and there is a fingerprint recognition area in the upper left corner.There is an independent area in the lower right corner of the
C side. On it is a dynabook brand nameplate with white as the background. The words on it are gray, striving not to affect the unity of white. The same situation also appears on the border below the screen. The
D surface is also worth mentioning. On the right is the fan air inlet, and on the left is a small window. After opening this small window, there is the area where the memory stick is located. If the user wants to install/upgrade the memory stick, he does not have to remove the entire bottom shell, but unscrew a screw to complete the memory replacement.

Finally, let’s take a look at the interface situation. On the left side of the body are a power interface, two Thunderbolt 4 interfaces, one HDMI 2.0 interface, one USB 3.2 interface, and one 3.5mm audio interface; on the right side of the body are a network cable interface, one USB 3.2 interface, and one MicroSD card reader. Such a richness of interfaces is a routine operation of Japanese manufacturers, especially thin and light laptops and network cable interfaces, which is really rare; compared with many single Type-C or single lightning interface models, the dual lightning 4 interface can simultaneously power the notebook + expand the screen or transmit data, which is convenient and practical.

dynabook EX40L-J is equipped with i5-1135G7 processor, 10nm process, four cores and eight threads, basic frequency 2.4GHz, maximum turbo frequency 4.2GHz, 8MB three-spatio, and is currently a very mainstream processor.

Although my test prototype only has 8GB of single-channel memory, the theoretical performance score of this i5-1135G7 is not at a disadvantage compared to other thin and thin items, which means that its performance release should be very good. So I checked its power consumption settings. The power consumption of PL2 is as high as 64W and the PL1 is as high as 28W. This really surprised me for a thin and thin item for office work. After all, there are many business tests. Due to its own positioning issues, I won’t care much about performance. However, this dynabook EX40L-J has the desire to roast it quickly and see if it can be maintained at 28W.
Stress FPU mode used in AIDA 64 system stability test, the test time is 30 minutes, the CPU power consumption is 28W, the temperature is about 89 degrees, and the entire core frequency fluctuates between 2.9GH and 3.2GHz, which can indeed maintain high power consumption at 28W. It is rare for business instinct to have such performance.

3, battery life test
Business users often need to travel frequently and go out for public use. It is common for office work without power, so this product needs to work hard on battery management. First of all, the dynabook EX40L-J is equipped with a 53WH battery, and the system is built-in battery management software. Unlike other products, it may only have one energy-saving mode to turn on or off. dynabook EX40L-J can also adjust the energy saving level by itself, affecting the display brightness of the screen, the time to turn off the hard disk, the time to turn off the display screen, and the time when the computer enters sleep. It can also display the power consumption of the entire machine at all times.
In addition to this function, the peak power transfer function is also a very interesting function. You can manually select the time you use your computer. The system will automatically optimize the battery power and balance the power consumption needs during peak power consumption. In terms of battery life test, PCMARK 10 is used for testing, Wi-Fi is connected throughout the whole process, and the energy-saving mode is turned on. The final battery life is 10 and a half hours, and the battery life is at the current mainstream level.

4, summary
this dynabook EX40-J gives. What impressed me most is that it has an all-white body, which is extremely rare in the current laptop market. It is difficult to find products with similar designs, and its appearance is unparalleled. Its performance surprised me even more. The business capital also has a full power consumption of 28W, which is really rare, and it has done a good job in battery management and interface ease of use. Overall, the dynabook EX40-J is a very innovative business masterpiece suitable for young white-collar workers.
