▲Zhao Yang K49A review
Zhao Yang series of notebooks are further expanding the application of the notebook crowd to a wider range of areas, in the original some of the main industry (education, finance, information, government) outside of the medical, scientific research, and even the military and other enterprises are the current Zhao Yang series of products to serve the object.
What is the difference between Zhaoyang K series and E series?
Zhao Yang notebook now has two series K series and E series, K series is relatively more high-end, with carbon fiber skin shell, can support up to 8GB DDR3 1600 memory, optional mSATA 16GB SSD, built-in Intel wireless card, can realize Widi technology, built-in professional-grade NVIDIA NVS5400M 128-bit discrete graphics, Bluetooth, Bluetooth, and so on. 128-bit discrete graphics, Bluetooth 4.0 with APS hard disk protection technology, screen protection rubber ring and more.
What are the improvements of the Zhaoyang K49A over its predecessor, the K47A?
The K49A not only distinguishes itself from its predecessor in appearance, becoming more introverted and robust. The K49A has also been significantly upgraded in terms of configuration, with the third-generation ivyBridge series of processors and the 7 series of PCHs fully enabled, which improves performance while increasing power consumption control and expansion capabilities.

Zhaoyang K49A machine design
Lenovo Zhaoyang series of notebook design simple and tough, all-black body to give a feeling of maturity and steadiness, with a hint of ThinkPad's shadow, especially the design of the top cover, the adoption of carbon fiber + skin-like coating are look upscale.
The Zhaoyang series is not equipped with a roll cage, but the top cover of the Zhaoyang K49A is still excellent, using carbon fiber material, the surface has a skin-like coating, when we press the top cover with our hands, the top cover deformation is relatively small, which can play a good role in protecting the screen.
▲The palm rest is made of hard engineering plastic
The palm rest of the K49A and the D-side are made of engineering plastic, which is still very good, not easy to leave fingerprints, and it can reduce the heat conduction, so that it won't be obviously warmed up after using it for a long time. We can see that the palm rest of the Zhaoyang K49A has a large angle of inclination to the keyboard (both at the joints between the keyboard and palm rest and at the outer edges of the palm rest), which seems to be like a wave holding up the center part of the palm rest, and the palms of your hands will just be in this area when you're actually using it, with a natural downward tilt and a very snug fit.

Interface: full USB3.0 power configuration
After looking at the shell and palm rest design of the ZHAOYANG K49A, let's take a look at the product's interface design in a circle around it.
▲Zhao Yang K49A two sides of the interface
Zhao Yang K49A rear only a power connector. The main ports are concentrated on the left and right sides of the body. In terms of interface configuration, the business book Zhaoyang K49A do very well: VGA, HDMI, optical drive
, network interface, burner a lot. Here alone, Zhaoyang K49A USB3.0 interface is mainly set up on the left side, which frees up the right side of the USB2.0 is more suitable for low-speed devices such as mouse and keyboard. The interface layout is more reasonable.
▲Zhao Yang K49A interface spacing moderate
In the interface spacing test, the ZHAOYANG K49A fully reflects the design strength of the business book, all interfaces are spaced just right, VGA, RJ45, HDMI, USB3.0 can be inserted at the same time without conflict, to ensure that the maximization of the use of external devices. The right side of the interface is the same, compared to the left side of the layout is more relaxed.
Exterior: moderate size and weight
As a mature and robust business notebook, the shape and size of the Zhaoyang K49A is relatively moderate.
▲14-inch matte screen
The Zhaoyang K49A doesn't get an upgrade on the display screen, which still features a 14-inch matte 1366?768 resolution screen. Of course we've previously looked at the fact that the screen bezel on the Zhaoyang K49A is still very removable, meaning that if you want a higher resolution screen you just need to order it, or replace it yourself.
▲Zhao Yang K49 size measurement
After measuring the length and width of the ZHAOYANG K49A: 33.9?23.3cm, the thickness is 29.91x33.14mm, which is the middle size in the mainstream audio/video gaming notebook. Bare weight: 2.215Kg, travel weight: 2.660Kg. spindle using zinc metal, strong anti-corrosion rust, spindle maximum opening angle of 180 degrees.

Detailed design:
After seeing all the appearance of the ZHAOYANG K49A, let's open its top cover to see the control area. The first thing you see is the keyboard area, the Zhaoyang series still continues the classic X-shaped structure of the keycaps, the key range is long, rebound strong, feel good. As you can see from the layout below, the K49A is a 14-inch body but is not equipped with a small keyboard area.
▲Zhao Yang K49A's keyboard close-up
Located around the keyboard are several hard switches, such as power on, one-key rescue, one-key mute, and APS hard disk protection buttons, which seem to be very streamlined, but are really useful, and one of the more distinctive features is the APS hard disk protection switch, which allows the user to call out the management interface and set the hard disk protection level and response time. This ensures data security to a great extent.
▲Keyboard LEDs and more
Just like the ThinkPad, the Lenovo Zhaoyang K series doesn't have keyboard backlighting, but a single LED overhead light is more than enough to keep up with the darkness. In fact, I've always felt that backlighting is not very good, and can easily cause visual pollution, and this top light is much better, not only can you see the keyboard, and occasionally take some small information can also help to illuminate a little more practical.
