HP ProBook 4321s used the LED as the screen backlight, screen brightness, life and energy efficiency has improved. The caveat here is that the essential difference between the LED backlight and the LED screen. LED backlighting is a traditional backlight upgrade, but the screen itself still does not change, not the true sense of the LED screen. For consumers, buy notebook, also requires a clear understanding of this difference between the two, to avoid can not be business tamper with the concept.
Of course, although the use of LED backlight, but the benefits of our previous mention. With the HP ProBook 4321s angular mold design, the thickness of the screen is equally satisfactory.
The same with most notebooks, the HP ProBook 4321s is also top of the screen with a camera device. The special the Fengyun camera not only provides 2 million effective shooting pixels, and also supports face recognition technology. Users can pre-set the function, without a password can be opened only through their own facial contours encrypt the laptop's operating system security better.
The ProBook 4321s screen hinge is very worthy of our praise, embedded sinking of the shaft structure in order to save the body space played a very good help. The balanced shaft damping force operation requires only the user with one hand can be completed to open the screen.
Compared to most consumer products, notebook keyboard base surface seems simple and clear. Can see that in addition to the round power switch is located above the keyboard, the middle part of, the 4321s and did not design any shortcut keys, but all by the FN key combination shortcut functions. Power around the baffle surface mesh texture decoration.
The reason why in the beginning of the article mentioned the HP ProBook s series laptop is more like a business, consumer cross-border products, on the one hand, it is because it is equipped with discrete graphics performance is relatively balanced, the other is because it has such as chocolate keyboard kind of consumer notebook design. The advantages of chocolate keyboard without more, often stay long fingernails of female users should be said with deep feeling. In keyboard design, the 4321s performance is quite satisfactory.
Mentioned in the HP ProBook 4321s (HP ProBook 4321s battery) many consumer notebook design, and can not truly become a home laptop, biometric fingerprint reader in the palm rest part of the fuselage on the right to prove it came from a good description of this product. No doubt, the floating chocolate keyboard, fashion color are so vague thought that HP really consider to be the ProBook divided into the consumer product line, but the processing is in the details, but that the front of this laptop indeed from the commercial family.
In addition, in the right palm rest part, in addition to the biometric fingerprint reader, we can see many familiar Logo labeling. Energy Star, legitimate authority, the Windows 7 support for the ATI discrete graphics and the latest Intel Core i5 processor identification, are sufficient to show that this laptop will bring a good performance.
In the palm rest part of the fuselage on the left, one can be torn off the grid using the schematic that HP ProBoook 4321s touchpad support two touch technology. Through this technology, users can two fingers on the touch pad for a series of actions to achieve Web page drag and drop, picture rotation, zoom in operation. In actual use, we found that its sensitivity has yet to be improved, but the functionality provided is very convenient.
Finally, let us look at the notebook interface number and distribution. As a business notebook, HP ProBook 4321s offers a very comprehensive and rich interfaces. The picture above to see the left side of the fuselage not only has VGA, RJ-45, USB 2.0 common interfaces, but also placed a common consumer products-definition HDMI digital interface as well as commercial products indispensable to the E- SATA interface.
The right side of the fuselage, in order to provide ample room for mouse operation to the user, HP just added two USB 2.0 ports, the other part by the DVD burner filled. It can be said that the interface layout is quite reasonable.
Of course, the reasonable layout is much more than that. In the body in front of the left side of the 4321s to provide a set of audio input and output interface and a multi-card reader. The user does not need to worry about the external headphone cable is not long enough, but can also facilitate the realization of the digital deposit card will plug.
Although molds are subject to change, but compared to the HP ProBook 4321s to enhance the hardware configuration is more obvious. So after a few pages of this evaluation, we will focus on the performance test. Order, we are still used in practice, the overall test first, followed by a separate test of the major hardware.
First, let's look at the notebook on the specific hardware configuration. The same with all the new Core products, the ProBook 4321s also equipped with a standard Intel HM57 chipset, 4400mAh Li-ion ProBook 4321s Battery, use i5-520M processor, built-in Southbridge chips, support for DDR3 memory with Intel integrated graphics.
As a 13-inch product, its portability compared to 14 inches or higher specification product is undoubtedly the advantage is obvious. Although the machine in the weight and body thickness has yet to be improved, but taking into account is equipped with Intel's mid-range processor and discrete graphics, we do not need its too harsh in this regard. On the other hand, under the fine craftsmanship and stylish appearance, the 4321s are still able to have a more powerful performance also allows us to see a new trend of the development of business notebooks, and that is good enough for the crowd of all-round, balanced and broad.
