Notebook Channel on November 23rd Speaking of gaming notebooks, Lenovo’s “tough little y” is a household name. In 2009, Lenovo bought out all of NVIDIA's GeForce GT 130M graphics cards and used them in the IdeaPad Y450. Its avant-garde design and unique and powerful gaming performance made the Y450 in short supply from the day it was released, and the "strong little y" became an instant hit. . In the middle of this year, Lenovo launched Y480, Xiaoy's orthodox fourth-generation product. This machine is excellent in terms of appearance design, workmanship, and performance, and is better than similar models. However, its strength is not obvious enough. So, the fourth-generation complementary work of Xiaoy, Y400 is here!
Domineering muscle car style Lenovo y400n appearance display
Overall appearance
Through the detailed unboxing pictures shown to you yesterday, I believe you already have a general understanding of the appearance of y400n. As a newly named product, Lenovo y400n naturally has a certain gap with Y480 in terms of appearance. It not only removes the classic orange screen border, but also introduces the wrapped A and D surfaces of the U series, and carries out surface modification. The carbon fiber-like treatment looks more like a modified muscle car, full of strength.
Interface part
Compared with Y480, the interface of Lenovo y400n has been reduced, but fortunately it has introduced USB shutdown charging function and supports optical drive insertion and removal, which is more practical. The left side of the Y400 fuselage provides power supply, VGA, network cable, HDMI high-definition output andOne USB3.0; on the right side is a 3.5mm headphone/microphone jack, two USB2.0 (yellow port supports shutdown charging function), and UltraBay pluggable DVD burner drive.
Body weight
In terms of weight, Lenovo y400n weighs 2.475Kg with battery and 2.960Kg with power adapter. It is heavier than a game notebook of the same size. It is recommended to use Backpack carry.
Details: The keyboard is outstanding but the screen is a bit regrettable
Screen details
In terms of screen, Lenovo y400n notebook still uses a 14-inch mirror screen, and the resolution remains the same. At 1366×768, there are no surprises. The screen material is ordinary TN, and the picture quality is basically satisfactory.
JBL speakers
As a new member of the sturdy little y, Y400 continues to use JBL speakers. It performs well in treble and reproduces accurately. In terms of bass, thanks to the support of a built-in subwoofer, the sound depth is quite good and the performance is excellent.
Control feel
The y400n notebook is equipped with Lenovo’s most classic high-touch keyboard. The chocolate keycaps adopt a black and red two-color design, which looks very bright and has a certain curvature, which can be used It fits perfectly on your fingertips and feels comfortable to the touch. The key travel is long, the press is crisp and clear, the force feedback is just right, and the feel is outstanding, even better than business notebooks that focus on quality.
Battery information
Lenovo y400n comes standard with a six-cell battery with a capacity of up to 72Wh, which is much higher than the standard of about 50Wh for mainstream 14-inch notebooks. But if you take into account the configuration of the y400n, which does not come with a core graphics card and has the option of a second independent graphics card, the power consumption of the whole machine is not low, and 72Wh of power is very necessary.
Summary of this chapter:
As a member of the "strong family", Lenovo y400n inherits the most classic and practical design elements of Xiao y, including JBL high-quality speakers, which feel great. Called the industry's first high-touch chiclet keyboard, these make y400n more comfortable to use. But what is more regrettable is that the screen part of the phone has not been upgraded and remains at the mainstream level.
